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. �������������������������������������� � No thermal cracking FR4 compatible and wave solderable Extremely high Q above 50 MHz 300 250 Nonmagnetic option available 200 Ultra stable: no change with (t), (V) and (f) 150 Excellent for tuning and impedance matching 100 High flashover level 50 Withstands 2 mm bend test 25 0 Better than porcelain Applications Specifications Wave Solder Profile Reflow Solder Profile • MRI Coils Pre-heat 220 ~260 ºC 30 • • • • • • • Soldering RF Ablation CoolingSystems 300 Transmitters 250 RF Generators 200 10 sec. max.
