Thin-Film Resistors Expand Tight Tolerance and TCR Ranges

Stackpole Electronics’ thin film, precision RNCF Series has expanded its value ranges to be one of the broadest in the industry for 0.01% tolerances and 10 ppm TCR. The offering now includes: RNCF0402 – 49.9 ohms to 12K ohms; RNCF0603 – 24.9 ohms to 100K ohms; RNCF0805 – 24.9 ohms to 200K ohms; and RNCF1206 and larger sizes – 24.9 ohms to 500K ohms.

In addition to the value range expansion, the RNCF Series is also available in 0201 case size down to 0.5% tolerance and ±25 ppm (49.9 to 5K). Finally as the applications that require low temperature coefficient resistors continue to climb, so do the demands for precision resistors. To address this demand, Stackpole has expanded RNCF Series TCR range down to ±5 ppm for 0402, 0603, 0805, 1206, 1210, 2010 and 2512 case sizes.

The resistance value range improvement enables the RNCF to be used for a wide range of precision application requirements including instrumentation, precision controls, robotics, medical monitoring equipment. Pricing for the RNCF varies greatly depending on size, tolerance, and resistance value.
