RF Power Plate Capacitors for Higher Voltages
Class 1 Ceramic
FEATURES
• Low losses
• High reliability
• High voltage ratings
APPLICATIONS
These high technology are designed for usage in high
frequency heating and welding equipment were high voltage
ratings are required. The insulation rim made from silicone
rubber minimize the adverse effects of moisture, dust, and
other impurities in the working environment.
MATERIAL
Capacitor elements made from Class 1 ceramic dielectric
with noble metal electrodes.
Flexible connection terminals copper/brass, silver plated, to
allow for series and parallel interconnection
MARKING
Type designator, capacitance value and tolerance, rated RF
voltage, production date code, ceramic material code,
manufacturer logo.
FINISH
Noble metal electrodes and terminals are protective
lacquered.
The PEF 220 type features an insulating rim made from
silicone elastomer to minimize the adverse effects of
moisture, dustand other impurities in the working
environment and to improve the characteristics of the
electrical field.
