The GST 4020 high ohmic, non-magnetic, radial leaded resistor series from SRT Resistor Technology offers a wide resistance range from 1MΩ up to 1TΩ, power rating of 2W and voltage rating of 4000V trimmed or 6000V untrimmed (tolerances ≥5%), all in a small 4020 radial leaded package. By utilising SRT’s thick film resistor technology, these resistors are able to offer tolerances down to ±0.25% (between 1MΩ and 100MΩ) as well as a TCR of down to ±25 ppm/°C (between 1MΩ and 1GΩ) and a VCR as low as ±5 ppm/V (between 1MΩ and 100MΩ). The GST 4020 resistor series also features variable lead spacing and lacquer coating for climatic protection.

  • Radial leaded surface-mount thick film chip resistor
  • Available in any resistance between 1MΩ and 1TΩ
  • 4020 package
  • Power rating of 2W at +70°C
