As thin film chip resistors have become more readily available and less expensive, their usage has significantly increased across a variety of applications. However, when the application requires stability at higher temperatures under harsh conditions and over a long period of time, the performance of many nichrome thin film resistors is not good enough.
Stackpole recently released their RNCE series of thin film resistors with capability to withstand higher temperatures, high-moisture and high-sulfur environments, with exceptionally low changes in resistance over their functional lifetime.
The proprietary alloy of the RNCE is more resistant to moisture corrosion and improves long-term stability. The RNCE structure and materials enhance the series ability to withstand sulfur as well as temperature extremes. Stackpole’s RNCE offers operation at high temperatures up to 175°C as well as full power operation up to 85°C. This allows the RNCE to be used in a wider range of precision applications where standard thin film resistors cannot be used.
The RNCE is available in sizes from 0402 through 1206, in tolerances as low as 0.05% and TCR’s of 25 and 50 ppm. The outstanding stability of the RNCE is demonstrated by low resistance shifts of less than 0.1% for industry standard tests such as load life, temperature cycling, biased humidity, and short time overload.
Pricing for the RNCE depends on tolerance and TCR. Contact Stackpole or one of our franchised distribution partners for specific or volume pricing.
