RNCL thin film high-power anti-surge chip resistors

High power and accuracy are becoming increasingly important for power management in consumer electronics, computer and peripheral devices, measurement systems and industrial power control and delivery. There is a wide range of technology options for lower resistance values used for these applications. While all-metal elements are the common choice for high temperature, high power, high surge, and low TCR, this technology also tends to be the most expensive and usually only provides tolerances of 1% and wider. Small electronics and low to medium power supply architectures may not need the lower resistance values or highest current carrying capacity.

Stackpole’s RNCL provides high power ratings per chip size with resistance values down to 50 milliohms. It provides the high precision and stability you would expect from a thin film resistive element with tolerances down to 0.5% and TCR of 50 and 100 ppm. This series shows a very low resistance shift of less than 1% under IEC industry standard tests for short-time overload, load life, and biased humidity. In addition, the RNCL has significantly higher pulse handling than typical thin film chip resistors due to proprietary materials and design.

Pricing for the RNCL varies with size, tolerance, and resistance value. Contact Stackpole or one of our franchised distribution partners for volume pricing.
