The CHM 0805 high ohmic non-magnetic resistor series from SRT Resistor Technology offers a wide resistance range from 100kฮฉ up to 1Tฮฉ, power rating of 0.125W and voltage rating of 200V trimmed or 400V untrimmed (tolerances โฅ5%), all in a small 0805 surface mount package. By utilising SRT’s meander structured thick film resistor technology, these chip resistors are able to offer tolerances down to ยฑ0.5% (between 100kฮฉ and 100Mฮฉ) as well as a TCR of ยฑ25 ppm/ยฐC and a VCR as low as ยฑ100 ppm/V (between 100kฮฉ and 100Mฮฉ). The CHM 0805 resistor series contains no organics making them suitable for high vacuum applications and offer PtAg (platinum silver) terminations for conductive gluing and soldering.

The CHM high ohmic non-magnetic resistor series is also available with an extended high temperature range version (up to +300ยฐC). Please see the separate CHM-HT product pages for further information.
Lower tolerance, TCR and VCR options are available upon request. Please contact us for further information and availability.
The below table gives full specifications for each resistor model available including the CHM 0805 series:
1) At continuous power dissipation the dimensions of solder-pads have to secure a sufficient heat removal
2) TCR: in ppm/K; +25ยฐC…+125ยฐC; TCR lower than standard TCR (highest value) or value >100G: +25ยฐC…+85ยฐC
3) VCR: typical values, all negative, not for all TCR values available
