Description
The MCH3512 military grade high voltage chip resistor series from Ohmcraft® offers a voltage rating of 3.5kV, power rating of 2W and a resistance range from 10kΩ up to 50GΩ all in a 3512 chip size package. By utilising their patented Micropen® precision printing technology, they are able to provide a superior precision, thick-film surface-mount resistor. MCH3512 resistors offer very low noise, ultra-high stability with tolerances down to ±0.1% (between 10kΩ and 100MΩ), TCR as low as ±25 ppm/°C (between 1MΩ and 500MΩ) and VCR down to 1 ppm/V. Ohmcraft’s military SMT chip resistors have an extended TCR temperature range (-55°C to +125°C) and are stringently inspected.
