High Voltage Disc Capacitors, 20 kVDC
Screw Mounting, Class 2 Ceramic
MATERIAL
Capacitor elements made from class 2 ceramic dielectric
with noble metal electrodes.
Connection terminals: Thread terminal, brass, silver plated
Allowable torque: 5.0 Nm (44 lbf · in)
FINISH
The capacitor body of the HPD type is completely protective
lacquered. The HPC type feature a coating made from
silicone elastomer to minimize the adverse effect of
moisture, dust and other impurities in the working
environment.
MARKING
Capacitance value and tolerance, manufacturer logo.
FEATURES
• High reliability
• Wide range of capacitance values
APPLICATIONS
HPC and HPD high voltage capacitors made from
class 2-ceramic dielectric can be used as coupling and
bypass capacitors where low power ratings are required and
larger capacitance changes with temperature can be
tolerated.

MOUNTING GUIDELINES
• Avoid installation in which too much torque is applied to the capacitor elements. Screw torque limit must be 5.0 Nm (44 lbf · in.)
• Do not use screws whose thread is longer than specified in the datasheet
• The capacitor elements must not be used as a mechanical support for other devices or components
