CRANE POLYFLON - RP-VC18-22 - Capacitor.

HV/RF Capacitor - Non-Magnetic. High Voltage. High Power. High "a" Screwdriver Adjust Rotating Piston Series

PTFE anode and mount surfaces are metalized with electrodeposited copper. Polyflon's proprietary plating process eliminates the possibility of air being trapped between the PTFE and copper interface which could break down under voltage stress.

The invention relates to variable capacitors suitable for high frequency, high voltage, low loss applications. The capacitor is formed of at least two sections or elements which are relatively movable to achieve selective capacitance variation. The capacitor sections or elements each comprise a metallic layer, serving as an electrode, secured to a layer of dielectric material with the layers of dielectric material being of generally equal thickness and in contiguous slidable contact to form the variable capacitor.

Capacitance: 0.8-18pF

Voltage: 1KV, Peak test volts: 2KV.

Current: 1.7Amp.

Adjustable.

Housing: Teflon (PTFE) and Silver Plated.

Dimensions: 0.421" D x 1.436" high.
