Compliance & Certifications
RoHS Compliance Statement
REACH Declaration
Conflict Minerals Policy
All PRC products manufactured to ISO 9001:2015 standards and MIL-SPEC guidelines where applicable.
The Precision Wire-Wound Advantage
Why leading aerospace and medical manufacturers specify PRC wire-wound technology for critical circuits.
Ultimate Stability
Lowest TCR (Temperature Coefficient of Resistance) available, down to ±1ppm/°C.
High Pulse Capability
Robust wire element absorbs significant energy surges that destroy thin-film alternatives.
Unmatched Longevity
Hermetically sealed options for 20+ year service life in extreme environments.
Individual Series Datasheets
Single consolidated PDF per series — every part number, dimensional drawing, electrical specs, derating curves, and ordering information.
Why Wire Wound Shunts Outperform Alternatives
Low EMF construction (<0.3 to 1.5 μV/°C) vs up to 100 μV/°C in tin oxide alternatives
Superior overload and surge current handling capability
A single PRC shunt replaces 2+ thin film or metal strip parts
Pure copper terminals avoid thermocouple errors in low-value shunt applications
Critical for accurate voltage drop measurement in precision metering
