SRT CHM 2010-HT Series

SRT CHM 2010-HT Series

The CHM 2010-HT high temperature, high ohmic non-magnetic resistor series from SRT Resistor Technology offers the same features as the CHM 2010 range, while allowing for high temperature applications of up to 300°C. The main features comprise of a wide resistance range from 100kΩ up to 1TΩ, power rating of 0.5W and voltage rating of 1500V trimmed or 2000V untrimmed (tolerances ≥5%), all in a small 2010 surface mount package. By utilising SRT's meander structured thick film resistor technology, these chip resistors are able to offer tolerances down to ±1% (between 100kΩ and 1GΩ) as well as a TCR of ±25 ppm/°C (between 100kΩ and 10GΩ) and a VCR as low as ±25 ppm/V (between 100kΩ and 100MΩ). The CHM 2010-HT resistor series contains no organics making them suitable for high vacuum applications and offer PtAg (platinum silver) terminations for conductive gluing and soldering.

The final measuring of the resistors takes place at room temperature (independent of TCR).

Please pay attention to the interconnection technology at high temperature applications.

The below table gives full specifications for each resistor model available including the CHM 2010-HT 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
