Raleigh, N.C. SEI Electronics Inc. has expanded its line of precision thinfilm nichrome chip resistors with the introduction of the RNC Series that provides a tighter tolerance down to 0.01% and a temperature coefficient of resistance (TCR) to ±5 ppm/°C.
Previously, tolerances less than 0.1% and TCRs lower than 25 ppm were available only with tantalum nitride chip resistors, said the company. Typical applications include precision circuits in telecommunications, instrumentation, military, medical equipment and power supplies.
Pricing for the RNC Series resistor (0603 to 1206 case sizes, 0.1%, 25 ppm) is approximately $0.15 each. Delivery is from stock to six weeks.
