SRT CHS 2512 Series

Product Features

Non-magnetic thick film chip resistor
Resistance range from 10MΩ to 1TΩ
Tolerances from ±0.5% to ±30%
TCR from ±25 ppm/°C to ±1000 ppm/°C
Power rating of 1W (at +70°C)
Temperature range from -55°C up to +155°C

Applications

The CHS 2512 high ohmic non-magnetic resistor series from SRT Resistor Technology offers a high resistance range from 10MΩ up to 1TΩ, power rating of 1W and voltage rating of 1500V trimmed or 2000V untrimmed (tolerances ≥5.0%), all in a small 2512 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), TCR as low as ±25 ppm/°C (between 10MΩ and 500MΩ) and a VCR as low as ±25 ppm/V (between 10MΩ and 100MΩ). The CHS 2512 resistor series contains no organics, making them suitable for high vacuum applications and offer PtAg (platinum silver) terminations for conductive gluing and soldering.

The CHS high ohmic non-magnetic resistor series is also available with an extended high temperature range version (up to +300°C). Please see the separate CHS-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 CHS 2512 series:

¹⁾ At continuous power dissipation the dimensions of solder-pads have to secure a sufficient heat removal
²⁾ Continuous operating voltage (U_, U_eff): 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
