EMI LEADED FILTERS
FEED-THRU CAPACITORS
SUBMINIATURE
DF220, DF221(H), DF430, TF240(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.
