Better Flexibility For Custom Parts

PRC's precision wire wound resistors are ideal for short run development projects as well as long runs that are needed in a hurry. Set ups and tooling are easier to assemble than other resistor types and specs can be quickly transferred from the model shop or laboratory to the production floor.

Buy Only What You Need

Why buy 50 pieces or more if all you need are a few resistors for testing or a dozen parts to complete your requirement? Small quantity lots or high volume production quantities are accurately checked 100% to assure specified limits and delivered on-time to meet critical deadlines.

Large Selection

You can specify any resistance value or decimal part of an ohm from 0.001 ohm to 10 Megohms with tolerances to ±0.005% and TCR's to 0±1ppm/°C. We also provide temperature-sensitive resistors and compensators to +6000ppm/°C. as well as a complete line of 4-terminal thru-hole and SMD subminiature current shunts.

Low Value/Low TCR Combinations

PRC's extremely low values to 1 mΩ & TCR 0±15ppm/°C. provide better load-stability. This means the quality to resist permanent change is designed into the parts from the start for dependable and repeatable measurements piece-to-piece.

High Surge Current Handling

Many other resistor types on the market require at least two or more parts to equal the power and overload capabilities of one PRC resistor. That is one of the reasons why our 3 and 5 watt precision shunt values are so popular.

Pure Copper Terminals

Why copper? Because PRC's hot-tinned commercially pure copper terminals offer better wetting characteristics and longer shelf life. Beware of copper clad or other materials that have a strong magnetic attraction and exhibit a high EMF - especially when specifying low value resistors. Another reason engineers want commerically pure copper is because of its low resistivity.

Low Thermal EMF Emitted Utilizing Copper Leads

All PRC's resistors, especially low values, have low EMF (< ±0.3-1.5 mV/°C.) with respect to the copper terminals. Many low value tin oxide and other general purpose resistors in the industry have thermocouple errors as large as 100 mV/°C. which degrade circuit performance. Try to avoid thermal gradients that could cause a large temperature difference across the resistor and specify resistors with low EMF construction.

Time-Proven Service

PRC's precision/power resistors are the choice of engineers and designers because of their reasonable costs and time-proven heavy duty service. Reliability and dependable quality year-after-year are "the real values" of precision wire wound resistors.
