Richardson RFPD Variable Capacitor 47273

Giga-Trims® are tiny trimmer capacitors which provide a straight-forward technique for fine RF and microwave circuits by eliminating time consuming methods of abrasive trimming, cut and try adjustment techniques, and interchange of fixed capacitors. The design evolved from the need for a virtually indestructible miniature trimmer with superior electrical characteristics. Giga-Trim® capacitors withstand the rigors of soldering heat, excessive tuning and rough handling. As a result of the excellent dielectric and insulation properties of the sapphire housing, high breakdown voltage is achieved. Incorporating the patented self-locking constant torque drive mechanism which eliminates the need for external bushing slots, the new Giga-Trim® offers many improvements: a fixed length, increased Q, essentially zero tuning noise and reduced susceptibility to solder flux intrusion during installation. A variety of mounting styles is available for vertical, printed circuit, panel, cavity and strip-line applications.
