In high-voltage environments, however, the stability and accuracy of these systems can be compromised due to the effects of a resistor’s voltage coefficient of resistance (VCR). Poor VCR can lead to resistance variations as the applied voltage changes, causing measurement errors and system instability.
Stackpole’s HVCR Series resistors have been specifically developed to provide superior precision and stability in high-voltage divider, monitoring, and control applications. Unlike other low VCR chip resistors currently available, Stackpole’s HVCR resistors undergo 100% screening to guarantee their VCR remains within the specified range. This rigorous testing ensures reliability and performance under demanding conditions, making them ideal for precision applications.
The HVCR Series offers:
- Resistance values from 10MΩ to 100MΩ
- Extremely low VCR, less than –5ppm/V for the 1206 package and less than –2ppm/V for the 2512 package
Pricing for the HVCR varies with size.
