Approvals
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 performance
levels. AC feedthrough capacitors are designed and
approved for up to 300 VAC 50/60 Hz operation.
