ATC’s 800 C Series offers superb performance in demanding high
RF power applications requiring consistent and reliable operation.
The combination of highly conductive metal electrode systems,
optimized case geometries, and proprietary dielectrics, yields the
lowest ESR. ATC’s new NPO low loss rugged dielectrics are
designed to provide superior heat transfer in high RF power
applications. Ultra-low ESR and superior thermal performance
insure that the 800 C Series products are your best choice for high
RF power applications from VHF through microwave frequencies.
Typical functional applications: Bypass, Coupling, Tuning, Impedance
Matching and DC Blocking.
Typical circuit applications: HF/RF Power Amplifiers, Transmitters,
Antenna Tuning, Plasma Chambers and Medical (MRI coils).
