RF Power Pot Capacitors
for Dielectric Heating Equipment, R16 HQ Ceramic Dielectric
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.
