SRT CHM 2512 Series

SRT CHM 2512 Series

The CHM 2512 high ohmic non-magnetic resistor series from SRT Resistor Technology offers a wide resistance range from 100kΩ up to 10TΩ, power rating of 1W and voltage rating of 2500V trimmed or 3000V untrimmed (tolerances ≥5%), all in a small 2512 surface mount package. By utilising SRT's meander structured thick film resistor technology, these chip resistors are able to offer tolerances down to ±0.5% (between 100kΩ and 100MΩ) as well as a TCR of ±25 ppm/°C (between 100kΩ and 10GΩ) and a VCR as low as ±10 ppm/V (between 100kΩ and 100MΩ). The CHM 2512 resistor series contains no organics making them suitable for high vacuum applications and offer PtAg (platinum silver) terminations for conductive gluing and soldering.

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 2512 series:

SRT CHM Specifications

1) At continuous power dissipation the dimensions of solder-pads have to secure a sufficient heat removal
2) TCR: in ppm/K; +25°C...+125°C; TCR lower than standard TCR (highest value) or value >100G: +25°C...+85°C
3) VCR: typical values, all negative, not for all TCR values available
