Accutrim™ 1240 Series

1/4W, 5% Tolerance, Rectangular Trimmer Potentiometers

Vishay Foil Resistors

Multiturn, Bulk Metal® Foil Technology, Ultra High Precision Trimmer Potentiometer

Product Description

The Accutrim™ 1240 series offers a multi-fingered, noble metal wiper engaging a planar surface of etched foil for low TCR end-to-end (five times tighter than required by MIL-PRF-39035 Char. H) and through the wiper. Other technologies, such as wirewound and cermet trimmers, have a fair TCR end-to-end, but cannot be relied upon to demonstrate an acceptable TCR through the wiper, which is an important element in the precise adjustment of circuits subject to temperature fluctuations.

The devices provide unidirectional, infinite resolution, which when synthesized by a combination of an absolutely uniform resistance material, multiple wiper contact points, and multiple resistance circuit paths, yields a uniquely accurate settability of less than 0.05%. There are no turns of wire to be traversed, causing a step function, and no contact resistance variation to cause an irregular change in resistance with mechanical adjustment.

Vishay Foil's Accutrim™ 1240 series features a resistive element which possesses a unique inherent temperature and load life stability. Their advanced, virtually back lash free adjustment mechanism makes them easy to set quickly and accurately, and maintains that setting through temperature cycling and vibration, as well as thermal and mechanical shock. A unique feature of Vishay Foil trimmer is its stability in the vibration environment, which eliminates the need for unwanted adjustments.
