ABSTRACT:
A variable electronic component in the nature of a trimmer capacitor for use in a subminiature electronic circuit is adapted to provide a desired wide range of impedance characteristics. The variable electronic component is constructed of a sealed housing having an impedance varying piston driven by a screw supporting a non-axially extending tab or threaded member. The piston includes a cylindrical member which, through conjoining with a cylindrical member of dielectric material, provides a varied range of capacitance to the trimmer capacitor.
