Nidec Copal Electronics

Single Turn, Cermet, Sealed, Trimmer Potentiometer

Product Description

Copal Electronics brings extensive thick film technology, lead connection technology, contact sealing technology, wiper technology, and others to its lineup of cermet trimmer potentiometers. Keeping pace with advances in information equipment, IC, LSI, microcomputer control and other advances, increased functions, and miniaturization of equipment, copal Electronics cermet trimmer potentiometers come in an increasing number of variations from through hole pin types, to surface mount and chip types, responding to the needs of a wide range of equipment.

Copal Electronics cermet trimmer potentiometers cover a wide range of manufacturing conditions and use environments, with sealed construction for higher reliability. Copal Electronics provides an extremely thin and compact trimmer on your surface mount board. O-ring sealing and high temperature resistance allow to handle this component with the same soldering and cleaning methods of other SMD's.
