Approvals
Feedthrough filters offer a high insertion loss across a
broad band of frequencies from a few tens of kHz up
to the GHz region. In general, feedthrough filters offer
a higher level of EMI suppression than feedthrough
capacitors of the same current rating. This is
particularly relevant to applications where source
impedance is smaller than 50 Ω. Different versions are
available offering a wide selection on operating
currents and performance levels. AC feedthrough
filters are designed and approved for up to 300 VAC
50/60 Hz operation.
