Better Flexibility For Custom Parts
PRC's precision wire wound resistors, wire wound sensors & wire wound shunts are ideal for short run development projects as well as long runs that are needed in a hurry.Wire wound electrical components have easier setup and tooling procedures than other resistor types so your precision specifications 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 components 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 Megaohms with tolerances to ±0.005% and TCR's to 0±1ppm/°C. We also provide temperature-sensitive wire wound resistors and wire wound compensators to +6000ppm/°C. as well as a complete line of precision wire wound 4-terminal thru-hole and SMD subminiature current sensing shunts.
Low Value/Low TCR combinations
PRECISION RESISTOR COMPANY's ability to accomplish 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 electrical component types on the market require at least two or more parts to equal the power and overload capabilities of one of PRC's precision wire wound component. That is one of the reasons why our 3 and 5 watt precision shunt values are so popular.
Pure Copper Terminals
Why copper? Because PRECISION RESISTOR COMPANY'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 precision wire wound resistors sensors or shunts. Another reason engineers want commercially pure copper is because of its low resistivity.
Low Thermal EMF Emitted Utilizing Copper Leads
All PRECISION RESISTOR COMPANY's precision wire wound resistors, precision wire wound sensors and precision wire wound shunts, especially low values, have low EMF (< ±0.3-1.5 mV/°C.) with respect to the copper terminals. Many low ohmic value tin oxide and other general purpose resistors, sensors & shunts 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, sensor or shunt so be sure to specify wire wound type precision electrical components with low EMF construction.
Time-Proven Service
PRECISION RESISTOR COMPANY's precision power wire wound electrical components 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 PRC's precision wire wound resistors, sensors & shunts.
