EMI SUPPRESSION FILTERS
DISC-TYPE
DS310/H, DST310/H & DSS310/H Series
®
Disc-type EMIFIL DS310, DST310 and DSS310 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.
