This ferrite bead generates a high impedance which at high frequencies mainly consists of a resistance element. The BLM series is effective in circuits without stable ground lines because the BLM series does not need a connection to ground. Chip sizes of.6.3,..5,.6.8, 2..25, and 4.5.6mm are cataloged. (The BLA series of array type chip ferrite beads is also cataloged.) The nickel barrier structure of the external electrodes provides excellent solder heat resistance.!features The BLM series comprises the series (for digital interface), the A series (for standard), the B series (for high speed signal), the P series (for large current), and the H/E series (for GHz range noise suppression).. BLM series For Digital Interface The BLM series can be used in Digital Interface. esistance of BLM series especially grows in the lower frequency range. Therefore BLM series is less effective for digital signal waveform at low frequency range and can suppress the ringing. 2. BLMA series For Standard The BLMA series generates an impedance from the relatively low frequencies. Therefore the BLMA series is effective in noise suppression in the wide frequency range (3MHz several hundred MHz). 3. BLMB series For High Speed Signal The BLMB series can minimize attenuation of the signal waveform due to its sharp impedance characteristics. Various impedances are available to match signal frequency. 4. BLMP series For Large Current The BLMP series can be used in high current circuits due to its low DC resistance. It can match power lines to a maximum of 6A DC (BLM4P). 5. BLM8H/E series For GHz ange Noise Suppression The BLM8H/E series has a modified internal electrode structure that minimizes stray capacitance and increases the effective frequency range.

28 !Note C3E9.pdf Features (BLM_B Series) The chip ferrite bead BLM series comprises ferrite beads in the shape of a chip. This ferrite bead generates a high impedance which at high frequencies mainly consists of a resistance element. The BLM series is effective in circuits without stable ground lines because the BLM series does not need a connection to ground. The nickel barrier structure of the external electrodes provides excellent solder heat resistance. The BLM_B series can minimize attenuation of the signal waveform due to its sharp impedance characteristics. Various impedances are available to match signal frequency.

Equivalent Circuit Features (BLM8H series). BLM8H series is realized high impedance at GHz and suitable for noise suppression from 5MHz to GHz range. The impedance value of HG/HDtype is about three times as large as that of A/Btype at GHz, though the impedance characteristic of HG/HDtype is similar to Atype at MHz or less. 2. HGtype is effective in noise suppression in wide frequency range (several MHz to several GHz). HB/HDtype for highspeed signal line provides a sharper rolloff after the cut off frequency. HKtype for digital interface is effective in suppressing the ringing because resistance especially grows in the lower frequency. 3. The magnetic shielded structure minimizes crosstalk.

135 !Note C3E9.pdf EMIFILr (Soldering and Mounting). Standard Land Pattern Dimensions The capacitor type Chip EMIFILr (NFp series) / Chip EMIGUADr (VFM series) suppress noise by conducting the highfrequency noise element to ground. Therefore, to obtain maximum performance from these filters, the ground pattern should be made as large as possible during the PCB design stage. As shown in the right, one side of the PCB is used for chip mounting, and the other is used for grounding. Small diameter feedthrough holes are then used to connect the grounds on each side of the PCB. This reduces the highfrequency impedance of the grounding and maximizes the filter's performance.

Solder Paste Printing and Adhesive Application When reflow soldering the chip EMI suppression filter, the printing must be conducted in accordance with the following cream solder printing conditions. If too much solder is applied, the chip will be prone to damage by mechanical and thermal stress from the PCB and may crack. In contrast, if too little solder is applied, there is the potential that the termination strength will be insufficient, creating the potential for detachment. Standard land dimensions should be used for resist and copper foil patterns. When flow soldering the EMI suppression filter, apply the adhesive in accordance with the following conditions. If too much adhesive is applied, then it may overflow into the land or termination areas and yield poor solderability. In contrast, if insufficient adhesive is applied, or if the adhesive is not sufficiently hardened, then the chip may become detached during flow soldering process.

Using THE block type EMIFILr effectively The block type EMIFILr effectively prevents unwanted reflections and external noise from entering the equipment circuitry and power lines by grounding all the high frequency components which make up the noise. Therefore, if grouding is improperly done, the filters may be unable to achieve the performance they are capable of. To prevent this, be sure to observe the following instructions. () When designing the P.C. board, use all the available grounding terminals, and arrange the grounding circuit so that the area of the foil for the grounding circuit is maximized. (2) Minimize the distance between the P.C. board ground and the filter's grounding plate. Use throughhole P.C. boards. (3) Whichever P.C. board is used, push the filter into the P.C. board up to the terminal roots. (4) Do not connect PSG to CG by any other means except through the filter. (See the item. TEMINAL LAYOUT) [P.C.B. BOAD PATTENS] Use a bilateral P.C. board. Insert the BN into the P.C.board until the root of the terminal is secured. then solder.

158 !Note C3E9.pdf Noise Suppression Principles by DC EMIFILr. Function of DC EMI Suppression Filters DC EMI suppression filters absorb and eliminate high frequency noise which may produce electromagnetic interference in PC board circuits. These filters are used in secondary circuits, and are small in size and light in weight, which further enhances their excellent noise suppression functions. Chip and adhesive type filters can be mounted on PC boards automatically. These filters are effective in the suppression of radiation noise in computers, peripheral equipment, and digital circuit application equipment (including various types of microcomputer application equipment), and function to suppress noise in audio/visual equipment, which uses digital memory chips and DSP. These filters are also effective for improving the noise immunity of equipment used in noisy environments (such as electronic equipment for automobiles). 2. Noise Filter Suppression Principles Generally, noise problems occur when the noise source and electronic equipment sensitive to the influence of noise are located in close proximity to one another. In such situations, as shown in Figure at right, noise is conducted through a conductor, which produces an inductive field around the noise source. To overcome such noise problems, it is preferable to reduce the amount of noise generated by the noise source or improve the noise resistance of adjacent equipment. In order to satisfy equipment performance specifications and eliminate noise effectively at the same time, however, it is customary to reduce the amount of noise generated by the noise source, if it can't be eliminated altogether.

Configuration of EMI Suppression Filters (DC) DC EMI suppression filters are used to suppress noise produced by conductors. Noise radiation can be suppressed, if it is eliminated with a filter in advance. Generally, such noise suppression is achieved with DC EMI suppression filters, according to the capacitive and inductive frequency characteristics of the respective conductors in the circuit. Filters of this kind can be roughly divided into those : () employing a capacitor, (2) employing an inductor, (3) employing a capacitor and inductor combination. Continued on the following page. 57

159 !Note C3E9.pdf Noise Suppression Principles by DC EMIFILr Continued from the preceding page. 4. Capacitive Noise Suppression When a capacitor is connected (bypass capacitor) to ground from a noisy signal line or power line, the circuit impedance decreases as the frequency increases. Since noise is a high frequency phenomenon, it flows to ground if a capacitor has been connected to ground, thereby making it possible to eliminate noise. (See Fig.) EMI suppression filters employing a capacitor in this way are used to eliminate this type of noise. [Capacitive Noise Suppression] Noise+Signal/DC Power Noise = 2πfc Signal/DC Power f : Frequency c : Capacitance Value 5. High frequency Capacitor Characteristics Used for EMI Suppression Filters Even generalpurpose capacitors can be used for noise suppression. However, since noise has an extremely high frequency range, generalpurpose capacitors may not function as effective bypass capacitors, due to the large residual inductance built into the capacitor. All the capacitors used in MUATA's EMI suppression filters employ a 3 terminal structure or thrutype structure, which functions effectively even at high frequencies, thereby minimizing the influence of residual inductance. Consequently, an effective filter circuit can be formed even at frequencies exceeding GHz.

Inductive Noise Suppression When an inductor is inserted in series in a noise producing circuit (See Fig.), its impedance increases with frequency. In this configuration it is possible to attenuate and eliminate noise components (high frequency components). The MUATA EMI suppression filter functions in this way. [Inductive Noise Suppression] Noise+Signal/DC Power Noise = 2πfL Signal/DC Power f : Frequency L : Capacitance Value Continued on the following page. 58

160 !Note C3E9.pdf Noise Suppression Principles by DC EMIFILr Continued from the preceding page. 7. Characteristics of Inductors Used in EMI Suppression Filters Generalpurpose inductors also function to suppress noise when configured in series with a noise producing circuit. However, when generalpurpose inductors are used, resonance may result in peripheral circuits, signal wave forms may become distorted, and satisfactory impedance may not be obtained at noise frequencies (due to insufficient high frequency impedance characteristics). The inductors used for MUATA's EMI suppression filters are designed to function nearly as a resistor at noise frequencies, which greatly reduces the possibility of resonance and leaves signal wave forms undistorted. And since sufficient impedance is obtained for frequencies ranging to hundreds of MHz, these specifically designed inductors operate effectively to suppress highfrequency noise. (See Fig.) [Equivalent Circuit] (esistance element becomes dominant at high frequency.) [Example of impedance frequency characteristics of inductor type EMIFILr] Impedance [Ω] BL2N2.5 (f) Frequency [MHz] 8. CapacitiveInductive EMI Suppression Filters If capacitive and inductive suppression characteristics are combined, it is possible to configure a much higher performance filter. In signal circuit applications where this combination is applied, noise suppression effects which have little influence on the signal wave form become possible. This type of filter is also effective in the suppression of highspeed signal circuit noise. When used in DC power circuits, capacitiveinductive filters prevent resonance from occurring in peripheral circuits, thus making it possible to achieve significant noise suppression under normal service conditions. 9. Other EMI Suppression Filters In addition to the capacitiveinductive filter, MUATA also has an EMI suppression filter (EMIGUADr) combining a capacitor with a varistor, useful for surge absorption; and a common mode choke coil effective, for common mode noise suppression. MUATA also has a range of builtin filter connectors which greatly reduce filter mounting space requirements. Continued on the following page. 59

161 !Note C3E9.pdf Noise Suppression Principles by DC EMIFILr Continued from the preceding page.. Expressing EMI Suppression Filter Effects EMI Suppression Filter effects are expressed in terms of the insertion loss measured in the circuit, normally specified in MILSTD 22A. As shown in the 5Ω impedance circuit in the Figure at right, insertion loss is represented by the logarithmic ratio of the circuit output voltage with and without a filter in the circuit, which is multiplied by 2 and expressed in db. Therefore, an insertion loss of 2dB indicates an output voltage ratio (B/C) of /, and an insertion loss of 4dB indicates an output voltage ratio (B/C) of /.
