ATC, the industry leader, offers new improved ESR/ESL performance
for the 100 C Series RF Capacitors. This high Q multilayer capacitor
is ultra-stable under high RF current and voltage applications. High
density Porcelain construction provides a rugged, hermetic package.
ATC offers an encapsulation option for applications requiring extend-
ed protection against arc-over and corona.
Typical functional applications: Bypass, Coupling, Tuning, Impedance
Matching and DC Blocking.
Typical circuit applications: VHF/UHF RF Power Amplifiers, Antenna
Tuning, Plasma Chambers and Medical (MRI coils).
*For leaded styles only.
