Pot Capacitors for Coupling Purposes
MODEL:
The ceramic capacitor element is housed in a rugged silver
plated copper can. This construction allows additional “Belt-
contacting” of the outer electrode terminal over the copper
can shaft.
The results are short conduction paths with low impedance
and low inductance as well as protection of the outer noble
metal electrode.
FINISH:
Insulating rim protected with silicone rubber.
MATERIAL:
Capacitor elements made from Class 1 ceramic dielectric
with noble metal electrodes.
Connection terminals of the inner electrode and outer
electrode’s covering can made from copper/brass, silver
plated.
MARKING:
Type designator, Capacitance value and tolerance, Rated
voltage (peak value), Production date code, Ceramic
material code, DRALORIC Logo, Serial number.
