Northumberland, England - High-voltage precision thin-film resistors from TT Electronics Welwyn Components offer high stability under temperature fluctuations of 5 ppm/ degrees C and a tolerance down to 0.01 percent.
The CAR series of ultraprecision metal film resistors offers three power ratings-0.25, 0.33 and 0.5 watt-at 70 degrees C ambient, with limiting voltages of 250, 350 and 500 V, respectively. Resistance ranges from 10 ohms to 10 megohms with temperature coefficients of resistance to 5 ppm/ degrees C. The operating temperature range is 55 degrees C to 155 degrees C.
The resistors, with a specially formulated epoxy coating, are billed as highly reliable with superior moisture performance and a typical long-term damp-heat stability of 0.02 percent. The series is priced at 60 cents each for a 0.2 percent, 10 ppm/ degrees C part. Delivery is four to six weeks.
