2 This is the PDF file of catalog No.CE. No.CE.pdf MUATA entered the suppression filter field at an early stage in response to serious problems stemming from electromagnetic interference between electronic equipment. These pioneering efforts in the filter field resulted in the development and worldwide marketing of the EMI Suppression Filter (EMIFIL ). In 979, MUATA successfully developed an onboard type EMIFIL, thereby realizing a solution to PC board noise suppression. In 98, the EMIFIL class of onboard filters ware further developed to produce a chipbased EMI suppression filter, thus substantially improving noise suppression in compact electronic equipment. Based on more than thirty years of ceramic dielectric and ferrite technology experience, MUATA's full range of highperformance EMIFIL serve to overcome and control all types of electronicequipment noise problems. Further, MUATA's various noise suppression circuits, designed for the diversified needs of the electronic industry, offer great advantages in the pursuit of noisefree equipment, etc. Currently, MUATA is completing a system for the analysis and solution of noise problems. For the finest in noise suppression components, boards, and related equipment contact the nearest MUATA sales office.!about OPEATING CONDITION Noise suppression levels resulting from MUATA's EMI suppression filters (EMIFIL ) may vary, depending on the circuits and ICs used, type of noise, mounting pattern, lead wire length, mounting location, and other operating conditions. Be sure to check and confirm, in advance, the noise suppression effect of each filter, in actual circuit, etc., before applying the filter in a commercialpurpose equipment design. EMIFIL for both DC and AC power supplies, and thrutype EMI suppression filters for highfrequency equipment (thrutype EMIFIL ) are available. For details, contact the nearest MUATA sales office.

7 This is the PDF file of catalog No.CE. No.CE.pdf Typical Application of EMI Suppression Filter (EMIFIL ) for DC line The main applications of EMIFIL for DC lines are as follows: Descriptions of these applications are based on standard digital PC board. Typical applications of EMIFIL in PC boards can be divided into four types:. Elimination of non desirable harmonics in high speed signal lines High speed clock signals, for example, contain higher level harmonic components, which can cause noise. These higher harmonics are reduced to within acceptable range by EMIFIL. For relatively low noise levels, chip ferrite bead inductors and chip solid EMIFIL (terminal capacitors) are used; for high level noise applications, signal line EMIFIL are used.. Elimination of noise in DC power supplies DC power supplies utilize high frequency current in converting AC power to DC power, etc., and these currents may cause noise. Since DC power supplies are designed to supply only DC current, the current flow is larger than that on the signal lines, which can cause DC resistance. Therefore, in such situations, EMIFIL having a wider noise suppression band and larger current capacity are used. For relatively low noise suppression, chip ferrite bead inductors and chip solid EMIFIL (terminal capacitors) are used; blocktype, DC power supply EMIFIL are used to suppress higher level noise.. Noise suppression in I/O cables Some I/O cables, when connected to PC boards, act as an excellent antenna, which can radiate noise and induce noise through coupling. To prevent this, EMIFIL are used at the connection point between the I/O cable and PC board to prevent noise from being introduced into the board. For relatively low level noise suppression, chip ferrite bead inductors are used; for high noise suppression, chip solid EMIFIL (terminal capacitors) are used. At high speed signal line connection points, signal line EMIFIL are used.. High voltage surge countermeasures EMIGUAD filters, which also have a surge absorbing function (using a varistor), are effective in preventing both higher harmonic noise and high voltage surges (such as electrostatic discharges) from interfering with PC board operation. As a countermeasure against noise radiation stemming from highspeed bus lines. For the prevention of cable noise radiation, including radiation from highspeed I/O lines.

Solder Paste Printing and Adhesive Application When reflow soldering the chip EMI suppression filter,/chip varistor, the printing must be conducted in accordance with the following cream solder printing conditions. If too much solder is applied, the chip will prone to be damaged 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/chip Varistor, apply the adhesive in accordance with the following conditions.

Enables simultaneous EMI suppression and surge protection The EMIGUAD VF, DSS76, and DSS7 series EMI suppression filters incorporate capacitors that have a varistor function to enable simultaneous EMI noise suppression and surge protection functions. These varistorenabled capacitors act not only as bypass capacitors against noise but also as surge protectors that route most of the surge current from high voltage power surges to ground to protect the circuits. Furthermore, the threeterminal structure provides excellent performance characteristics in the highfrequency range, making these filters effective against highfrequency noise and short risetime surges which are difficult to combat with ordinary capacitors and varistors.

No.CE.pdf Method of using the BNP and BN filter blocks, and applications.!using EMIFIL EFFECTIVELY The block type EMIFIL 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.. Minimize the distance between the P.C. board ground and the filter's grounding plate. Use of throughhole P.C. boards.. Whichever P.C. board is used, push the filter into the P.C. board up to the terminal roots.. Do not connect PSG to CG by any other means except through the filter.!application "Suppression of DC side ripple of the switching power supply Switching Power Supply BN +V CG "When BN is not used ( High frequency noise, max..v, can be seen. ) +.Vaa µs/div.v/div "When BN is used Noise can be almost ( suppressed by BN. ) +.Vaa µs/div.v/div!pat NUMBEING (Please specify the part number when ordering.)

No.CE.pdf EMI SUPPESSION FILTE DC Common Mode Choke Coil PLT/PLT9H Series Compact, Light Weight, Common Mode Choke Coil for DC Power Supplies for Common Mode Noise Suppression for Several MHz to Several Hundred MHz The PLT/PLT9H series DC common mode choke coils are EMI suppression filters that are effective against the common mode noise that can cause radiative noise in power supply lines and interface lines. PLT Unlike capacitorbased filters, these choke coils do not require a grounding terminal, making them applicable in situations where a stable ground cannot be obtained. PLT9H!FEATUES. The high degree of coupling enables effective suppression of common mode noise without appreciably altering the normal mode signal waveforms even when the signal and noise frequencies are close to each other..
