Ultra-High Precision Resistor Overall stability ±5 ppm/°C from +25°C to +65°C (incl. VCR & TCR)

We have developed new material combinations and processing methods, which make it possible to achieve a Thermal Coefficient of Resistance (TCR) as low as ±5ppm while maintaining the minimum Voltage Coefficient of Resistance (VCR).

Features:
■ Operating voltage up to 10kV
■ Non - conductive design
■ RoHS - compliant.
