EMI SUPPRESSION FILTERS DISC-TYPE DS31/H, DST31/H & DSS31/H Series Disc-type EMIFIL DS31, DST31 and DSS31 are T-type EMI suppression filters. The disc-type EMIFIL increases the self-resonant frequency of the capacitor by attaching two lead wires to one of the electrodes of the capacitor and increases the insertion loss by adding inductance to the lead in the DST and DSS types only. Frequencies to be suppressed can be selected by choosing the capacitance. They are also recommended for use as by-pass capacitors.

EMI SUPPRESSION FILTERS VARISTOR-CAPACITOR DSS71 Series The DSS71 uses a capacitor element which provides the varistor function. This varistor-capacitor not only works as a bypass capacitor but also lets high-voltage surges flow to ground. The varistor-capacitor used in the DSS71 has a 3-lead structure, so that its high frequency functions are substantially better than those of conventional capacitors. Furthermore, it is combined with ferrite bead to form a T-shaped filter circuit that most effectively suppresses EMI. The DSS71 efficiently removes fast-rising transients and high-frequency EMI above 5 or 6 MHz which conventional capacitors and varistor-capacitors are incapable of removing. Varistor-capacitors are used even where conventional EMI-filters fail. They are self-healing and effective in circuits having 5-6V impulses.

EMI SUPPRESSION FILTERS VARISTOR-CAPACITORS 3-TERMINAL STRUCTURE Appearance 12-22 223S M Ferrite bead: Absorbs high-frequency noise. Symbol NOISE ABSORPTION EFFECT OF VARISTOR-CAPACITOR DSS71 Series SCALE: 2V/Div. 1NS/Div. Varistor: Bypasses high-voltage surges to ground in order to protect circuits. Capacitor: Bypasses high-frequency noise. Waveform when a Varistor-Capacitor is not used (surge from a noise simulator). The reason the 3-terminal structure provides excellent high frequency characteristics. Bypass capacitors should logically be able to remove more noise as frequency increases. In actual fact, the electrodes and lead wires of the capacitor have series inductance as shown in Fig. 3, and this causes an LC resonance when the frequency is between 1MHz and 5MHz. As a result, when the frequency is higher than the self-resonance frequency, the noise suppression capability of the bypass capacitor is drastically reduced because the capacitor functions as inductor. To solve this problem, the DSS series has one side of the capacitor electrodes connected to two lead wires. This eliminates the series inductance to the capacitor. Furthermore, a ferrite bead is attached to each lead wire to form a T-shaped filter, thus providing efficient noise suppression. Varistor-Capacitor is used to suppress the surge shown below 12-22 223S Waveform after the noise passes through a Varistor-Capacitor. Protection of circuitry is achieved. M Conventional 2-Lead Capacitor 3-Lead Capacitor (DSS Series) The Varistor-Capacitor is capable of removing even 12V surges and will withstand 2V impulses.

EMI SUPPRESSION FILTERS BLOCK FILTERS FEATURES The EMIFIL BNP2 incorporates feed-thru type barrier layer capacitors in Pi circuits, obtaining significantly large insertion losses over an extremely wide frequency range from 15MHz up to 1GHz. The cut-off frequency is designed to be at several MHz, which is ideal for eliminating noise from any circuit in which the signal frequency and the noise frequency are relatively close together. BNP2/4 Series Block-type BNP2 filters completely eliminate noise from extremely wide frequency bands. The BNP2 is ideal for eliminating noise in logic signal circuits and is designed to perform superbly through the use of through-type barrier layer capacitors, and bead inductors. Each block contains a number of compact EMI suppression filters. In addition, the input/output terminals and the grounding terminal are aligned in the same direction, thus permitting fast and easy assembly on any type of PC board. APPLICATIONS Noise elimination from signal lines and DC power sources in engine control units, digital equipment and computer terminals. Since all noise in parallel signal lines can be eliminated by one filter block, minimum board space is utilized. There are no connections in the feed-thru current circuits, thus ensuring highly reliable performance. Both the input/output terminals and the grounding terminal are aligned in the same direction, permitting fast and easy installation on any type of PC board.
