Description

The HVA18 precision high voltage axial resistor series from Ohmcraft® offers a voltage rating of 15kV, a power rating of 3.6W and a resistance range from 100kΩ up to 50GΩ all in a cylindrical axial leaded through-hole package. By utilising their patented Micropen® precision printing technology, they are able to provide superior precision, non-inductive thick-film resistors. HVA resistors offer very low noise, ultra-high stability with tolerances down to ±0.1% (100kΩ to 100MΩ), TCR as low as ±50 ppm/°C and VCR down to 0.1 ppm/V.
