SRT CHS 1210 Series

SRT CHS 1210 Series

The CHS 1210 high ohmic non-magnetic resistor series from SRT Resistor Technology offers a high resistance range from 10MΩ up to 1TΩ, power rating of 0.35W and voltage rating of 300V trimmed or 600V untrimmed (tolerances ≥5.0%), all in a small 1210 surface mount package. By utilising SRT's thick film resistor technology, these chip resistors are able to offer tolerances down to ±0.5% (between 10MΩ and 100MΩ) as well as a TCR of down to ±25 ppm/°C (between 10MΩ and 100MΩ) and a VCR as low as ±25 ppm/V (between 10MΩ and 100MΩ). The CHS 1210 resistor series contains no organics, making them suitable for high vacuum applications and offer PtAg (platinum silver) terminations for conductive gluing and soldering.

The below table gives full specifications for each resistor model available including the CHS 1210 series:

SRT CHS Specifications

1) At continuous power dissipation the dimensions of solder-pads have to secure a sufficient heat removal
2) Continuous operating voltage (U_, Ueff): V ≤ √(P*R) or max. working voltage (the lower value)
3) TCR: in ppm/K; +25°C...+125°C; TCR lower than standard TCR (highest value) or value >100G: +25°C...+85°C
4) VCR: typical values, all negative, not for all TCR values available
