Ohmcraft HVR42 Series

Ohmcraft HVR42 Series

The HVR42 high voltage through-hole resistor series from Ohmcraft® offers a voltage rating of 20kV, power rating of 2W and a resistance range from 100kΩ up to 1TΩ all in a small radial leaded through-hole package. By utilising their patented Micropen® precision printing technology, they are able to provide a superior precision, thick-film through-hole resistor. HVR42 resistors offer very low noise, ultra-high stability with tolerances down to ±0.1% (between 100kΩ and 100MΩ), TCR as low as ±25 ppm/°C (between 1MΩ and 500MΩ) and VCR down to 0.05 ppm/V.
