SEI Expands Thin Film Chip Resistors to 5ppm and 0.01% Tolerance

RNC Series provides lower cost alternative to tantalum nitride…

RALEIGH, NC (Jan 9, 2004) - Resistor manufacturer SEI Electronics, Inc. has expanded its offering of precision nichrome thin film chip resistors, the RNC Series, to provide tighter tolerances down to 0.01% and temperatures coefficients to

+/- 5ppm per °C.

“With these recent additions to our precision nichrome offering, SEI now has one of the broadest product offerings in this area,” Kory Schroeder, SEI Product Engineering Manager explained. “Tolerances less than 0.1% and TCR’s lower than 25ppm were previously available only with tantalum nitride.  Our precision nichrome, RNC Series now provides a lower cost alternative to tantalum nitride for applications that are not moisture sensitive.”

Typical pricing for the RNC Series (0603-1206 case sizes, 0.1% 25ppm) of resistors is approximately $0.15 each, with lead times ranging from stock to 6 weeks. 0805 and 1206 case sizes in 0.1% tolerance and 25ppm are considered standard for values between 100 ohm and 100 K Ohm.

In addition, SEI offers ultra precision tantalum nitride chip resistors (TTF series) for moisture sensitive applications.  TCR’s down to 10ppm and precision tolerances to 0.02% are available.
