Vishay Draloric
RF Power Barrel 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 TOSZ model can be used as replacement for
fixed vacuum capacitors. The construction gives the
capacitors an advantage over fixed vacuum capacitors,
because there is no possibility of vacuum deterioration.
