RF Power Feed-Through Capacitors

with Mounting Tags, Class 1 Ceramic

MATERIAL

Capacitor elements made from class 1 ceramic dielectric

with noble metal electrodes.

Connection terminals:



made from copper / brass, silver plated.

For higher feed-through current, an additional feed-through

conductor must be provided.

FINISH

Capacitor body completely protective lacquered.



The contoured insulating rims are additionally glazed.

MARKING

Type designator, capacitance value and tolerance, rated

peak voltage, ceramic material code, production date code,
