PRC specializes in custom precision wire wound resistors, sensors, shunts & compensators exclusively. Our products are designed for low power ceiling applications, ranging to a max of 10 Watts, depending on part type and intended to be implemented in D.C. powered circuits.
Our wire wound parts are designed & constructed specifically to emit very low EMF & are quality controlled through the use of constant temperature oil baths to eliminate inconsistencies. They are inherently stable vs. time allowing for repeatable precision or accuracy from +/- 1% to as close as 1/200% (0.005%) and offer much improved overload capabilities when compared with other resistive materials which serve as economical fail safe solutions
We offer a versatile selection including both two and four terminal axial lead / through-hole, two and four tab surface mount, probe, also known as radial or printed circuit type & certain Mil-Styles. Modification of our standard catalog parts are also available in most cases, enabling a truly custom "made-to-fit" solution that your critical application demands.
(+) Positive Temperature Coefficient of Resistance (TCR) temperature compensators with a diverse selection of TCRs along with ultra low TC options from +/- 20 (.002%) down to +/- 1 PPM/Deg. C. (.0001%) as well as both standard inductive windings and non-inductive reverse-pi style winding patterns offered.
PRC's wire wounds are custom designed, allowing for adjustments of the measured resistance, resistance tolerance & TCR including low value "Kelvin Style" four-terminal precision current sensing shunts ideal for measuring voltage drops.
To be sure you have chosen the best possible resistor composition type and layout to meet the specification demands of your application, see the following technical articles, detailing the strengths & weakness of resistor types
