RF Power Pot Capacitors

for Coupling Purposes, Class 1 Ceramic Dielectric

MATERIAL

Capacitor elements made from class 1 ceramic dielectric

with noble metal electrodes.

Connection terminals of the inner electrode and the case

which covers the outer electrode terminal made from

copper / brass, silver plated.

FINISH

The ceramic capacitor element is housed in a rugged

silver-plated copper case. The electrical terminations are

made directly to the noble metal electrodes utilizing special

soldering techniques. This method of attachment provides a

strong, rigid connection of unsurpassed reliability. The TDFZ

types feature an umbrella-shaped coating rim made from

silicone elastomer to minimize the adverse effects of

moisture, dust and other impurities in the working

environment and to improve the characteristics of the

electrical field.

MARKING

Type designator, capacitance value and tolerance, rated

peak voltage, ceramic material code, production date code,

manufacturer logo.

ACCESSORIES ADDED

These pot capacitors are supplied with the necessary nuts,

screws and washers to make the connection to both

electrode terminals.

FEATURES

The ceramic capacitor is housed in a rugged silver plated

copper

case.

This

construction

allows

additional

“Beltcontacting” 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

electrode.

APPLICATIONS

Filter, bypass and coupling circuits were high voltage ratings

are required.
