The CHR 4020 non-magnetic resistor series from SRT Resistor Technology offers a wide resistance range from 1Ω up to 10MΩ, power rating of 2W3) and voltage rating of 500V trimmed or 1500V untrimmed (tolerances ≥5%), all in a small 4020 surface mount package. By utilising SRT’s thick film resistor technology, they are able to offer low tolerances down to ±0.5% (between 100Ω and 1MΩ) and TCR as low as ±50 ppm/°C (between +25°C and +85°C). The CHR 4020 resistor series contains no organics making them suitable for high vacuum applications and offer PtAg (platinum silver) terminations for conductive gluing and soldering.
Zero ohm jumper option available with a resistance value of less than 0.05Ω.
The CHR non-magnetic resistor series is also available with an extended high temperature range version (up to +300°C). Please see the separate CHR-HT product pages for further information.
Custom tolerance, TCR and VCR options are available upon request. Please contact us for further information and availability.
