For precision applications requiring surface mount chip resistors with high power demands, selfheating often leads to elevated circuit temperatures. Wide terminations offer an efficient and costeffective solution for minimizing power-related heat. By reversing the chip resistor's geometry and placing the terminations along its long sides, the hot spot temperature is reduced by 30% to 40%.

Stackpole’s RNWA series is available in the following size / power rating combinations:

• 0612 rated at 1W

• 1020 rated at 1.5W

• 1225 rated at 2W

In addition to operating at cooler temperatures, the RNWA series is anti-sulfur and provides precision tolerances as low as 0.1% and TCR down to 25 ppm. Its lower thermal resistance ensures stable and reliable performance at full power. These characteristics make the RNWA ideal for precision, high-power applications such as EV power systems, electric power trains, medical devices, and precision industrial and motor control.

Pricing for the RNWA varies with size, tolerance, and TCR. Contact Stackpole or one of our franchised distributor partners for specific or volume pricing.
