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 ºC and voltages to 4000 Vdc.

Exceptionally low ESR and superior thermal qualities

set the MCH/MCHN chip capacitors apart from

ordinary RF capacitors.
