6 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.

11 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.

12 EMI SUPPRESSION FILTERS VARISTOR-CAPACITORS 3-TERMINAL STRUCTURE Appearance S 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 S 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.

15 EMI SUPPRESSION FILTERS BLOCK FILTERS USING THE BNX SERIES EFFECTIVELY The block type filter 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. To maximize performance, proper grounding is required. To insure proper grounding, observe the following points: When designing the PC board, use all the available grounding terminals and arrange the circuit to maximize the area of the ground pattern. APPLICATION BNX2/3/5 Series Minimize the distance between the PC board ground and the filter s grounding plate. Insert the filter into the PC board up to the terminal roots.

18 FEED-THRU CAPACITORS SUBMINIATURE DF22, DF221(H), DF43, TF24(H) & DF331(H) Series Since the input and output terminals of these feed-thru capacitors are isolated and the inductance on the grounded side is very small, they can be used effectively to very high frequencies. These devices are suitable for suppression of radiation from TV tuners, car radios, car stereos and transmission devices and provide enhanced protection from external noise sources. These subminiature feed-thrus, which may be incorporated in 2.54mm pitch connectors, are ideal for miniature electronic equipment. FEATURES The use of barrier layer capacitors has resulted in smaller size and larger capacity than possible with conventional capacitors. The nickel alloy electrode is resistant to soldering heat and is free from migration in high humidity environments. Compact electronic devices can be achieved by incorporating this capacitor with a 2.54mm pitch packaging density such as installation in connectors. Simple construction allows mass production assembly techniques. DF43 Mounting Hole DF ±.2 D D. 2.4 max. 1. ±.1 D. Mounting Hole 2.15 ± ±.2 D. 2.7 ±.2 D. 2.5 ±.2 D D. 2.5 ±.3 3. ±.2 D..7 ±.3 2. ±.1 D.
