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. 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 C 30 * * * * * * * Soldering RF Ablation CoolingSystems 300 Transmitters 250 RF Generators 200 10 sec. max.
