This midget variable condenser capacitor is designed for precise RF tuning and frequency adjustment in compact vintage receiver circuits and test gear. Manufactured with interleaved aluminum plates on a low-loss insulation base, this unit provides smooth capacitance variation across its rotation angle. As an air-dielectric tuning capacitor, its electrical capacitance range (pF) is governed by plate surface area and mesh spacing rather than a fixed DC resistance rating. The 1/4-inch round shaft measures 5/8 inch in length, making it compatible with standard setscrew control knobs and dial drives.
