High-Voltage Metal-Film Resistors for Harsh Environments

September 02, 2014 by Jeff Shepard

Stackpole's RNV Series uses proprietary manufacturing processes and materials to provide a robust product that has excellent electrical performance under prolonged high-temperature and high-humidity stress. It can withstand 1000 hours at 40 degrees C, at least 90% relative humidity with cycled power on for 1.5 hours, off for 0.5. The RNV Series has a working voltage rating up to 1600Vdc and an overload voltage rating of up to 3200Vdc depending on resistance value.

This series meets IEC 60065.14.1 standards handling up to 7kV for 50 discharges of a 1nF capacitor. These metal film resistors are designed for applications requiring high voltage handling capability, high reliability, and stability. Examples of such applications include switching power supplies, power inverters, AC adapters, appliances, electronic ballasts, and displays and monitors.

The RNV is available in both 5% and 1% tolerances, and in standard ammo and tape and reel packaging. Pricing for 1% tolerances is around $0.04 each in full reel quantities.
