The exible 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.
Applications
• MRI Coils
• RF Ablation Systems
• Transmitters
• RF Generators
• Antenna Tuning
• Lasers
• RF Power Ampliers
• MRI Generators
