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.

Bending Test:
Mount the capacitor as shown at right and
press the ram bar until a 2.0 mm deflection is
achieved. There will be no visual damage and
the capacitors will meet the limits of methods JIS
