AC Feedthrough Capacitor
Approvalsn IEC/EN 60384-14 approval
n Rated currents from 10 to 200A
n 5kV pulse test capability
n Class Y2 capacitor
Typical applications
Feedthrough capacitors offer a high insertion
loss across a broad band of frequencies from
a few tens of kHz up to the GHz region. The
construction of feedthrough capacitors cause
a better suppression performance over a much
wider frequency range than a conventional
two-wire capacitor of equivalent value.
Different versions are available offering a
wide selection on operating currents and per-
formance levels. AC feedthrough capacitors
are designed and approved for up to 300VAC
50/60Hz operation.
n Very low internal series inductance.
n Very high self-resonant frequency.
n Self-healing dielectric.
n High quality and reliability.
n Through-bulkhead mounting.
n Anti-twist protection.
n Custom-specific or dual-versions on
request.
n Power line filter for 110/240VAC power
lines
n Increasing system and information security
n Power supplies
n Switching and cellular equipment
n Computer servers
n UPS power supplies
n Medical equipment
n Shielded rooms
