RF Power Pot Capacitors

for Dielectric Heating Equipment, R16 HQ Ceramic Dielectric

MATERIAL

Capacitor elements made from class 1 ceramic dielectric

with noble metal electrodes.

Connection terminals:



made from copper / brass, silver plated.

FINISH

Capacitor body completely protective lacquered.

These capacitors feature umbrella-shaped insulation rims

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.

FEATURES

These capacitors feature a Q-factor of greater than 10 000

which makes them ideal in operating frequency range from

0.1 MHz up to 30 MHz where high voltages and currents are

present. The TDZ model can be used as replacements for

fixed vacuum capacitors. The construction gives these

capacitors an advantage over fixed vacuum capacitors

because there is no possibility of vacuum deterioration.

APPLICATIONS

Dielectric heating equipments in industrial segment.
