Types MCH and MCHN Multilayer High RF Power Capacitors
2500 & 4000 Volt RF Capacitors for Medical Imaging Coils, Plasma Generators,
VHF/UHF Power Amplifiers and Antenna Tuning with Nonmagnetic Option
The flexible aluminum silicate dielectric eliminates
cracking and permits soldering to 260 C. These high
voltage, RF capacitors need no voltage derating at
temperatures up to 125 C and voltages to 4000 Vdc.
Exceptionally low ESR and superior thermal qualities
set the MCH/MCHN chip capacitors apart from
ordinary RF capacitors.
