Product Details | PRECISION WIRE WOUND VARIABLE RESISTOR
5905-00-838-3905 A resistor in which a sliding or rolling contact moves over an exposed area of the resistive element to change the ohmic value of the output. The functional tolerance (linearity) of the output is equal to or less than plus or munus 1 percent on linear outputs. Specified outputs such as sine, cosine, tangent, etc., shall be considered to be precision. For items having manually positioned taps designed to be set and fixed prior to use, see RESISTOR, ADJUSTABLE, For items with step by step variation, see RHEOSTAT and RESISTOR, STEP BY STEP. For tandem-mounted items designed to function together as an attenuator (and rated accordingly), see ATTENUATOR, VARIABLE. Excludes RESISTOR (1), VARIABLE, NONWIRE WOUND, NONPRECISION; RESISTOR (1), VARIABLE, NONWIRE WOUND, PRECISION; and RESISTOR (1), VARIABLE, WIRE WOUND, NONPRECISION.

What Our Customers Say
Thank you very much for the excellent service and professional customer care.
The service was excellent. I can think of no improvements to date that you can make regarding internet sales.
The representative for WBParts was efficient & handled our request in a timely & professional manner.
Tried two other sources, neither of them responded, was all done online, never spoke to anyone.
The response is quick and the price is often very good. We are completely satisfied.
