Trimmer

538 Series Trimmer Capacitor

USONIX’s 538 Series featured on this page is miniaturized for

today’s circuitry. All ceramic construction with optically flat inter-

faces provides tuning smoothness not obtainable with compression

type trimmers.

The silver electrodes are intimately bonded to the top surfaces of

the base and rotor. The terminals and other metal parts are nonfer-

rous and silver-plated to provide excellent conductivity and trouble

free soldering.

A variety of capacitance ranges, terminations and mounting provi-

sions makes these popular trimmers ideal for nearly all applications.
