RF Barrel / Doorknob Capacitor

Morgan Technical Ceramics Electroceramics (MTC Electroceramics) is an international manufacturer of advanced ceramic materials and components. MTC Electroceramics's Capacitor Division specialises in the development and production of dielectric and ferroelectric materials and components. The ceramic materials used in the above range are Type 1 dielectrics, these materials have very low dielectric loss and linear temperature coefficient of capacitance which make them ideally suitable for high power application where minimum capacitance change is required.

Features

Low dielectric loss resulting in low self heating.
Linear temperature coefficient.
Small size.
High Voltage / High Reactive Power Rating.

Applications include

Radio Broadcast Transmitters.
Antenna units.
Filter, bypass and coupling circuits in the frequency range 50kHz to 100MHz.
