TT electronics IRC Wirewound and Film Technologies Division has developed a rugged thick film resistor with voltage ratings up to 20KV. The CGH Series resistors have power ratings from 1/4W to 5W, and are available in resistance values ranging from 100kOhms to 2000MOhms at tolerances down to ±0.5%; with TCRs down to ±50ppm/°C. Voltage rating ranges from 750V to 20KV. The resistors precision can be further enhanced by ordering the resistors as matched pairs to provide divider accuracy down to ±0.1%.
