MODEL:
These capacitors feature a Q-Factor greater than 10 000
which makes them ideal in operating frequency ranges from
0.1 MHz up to 30 MHz where high voltages and currents are
present.
Solid cylindric brass terminals (50.8 mm/2” diameter) allow
plug-in compatible fuse clip mounting for vacuum capacitor
replacement. (Model TDFZ 125236).
FINISH:
Noble metal electrodes completely lacquered. Contoured
rim protected with silicone rubber.
MARKING:
Type designator, Capacitance value and tolerance, Rated
voltage (peak value), Production date code, Ceramic
material code, DRALORIC Logo, Serial number.
MATERIAL:
Capacitor elements made from Class 1 ”High Q” ceramic
dielectric with noble metal electrodes.
Connection terminals: Copper/brass, silver plated.
