Metal film resistors suit harsh environments

Stackpole’s RNV Series metal film resistors perform under prolonged high temperature and high humidity. They can withstand 1,000 hours at 40° C, at least 90% relative humidity with cycled power on for 1.5 hours and off for 0.5. They have a working voltage rating up to 1,600 Vdc and an overload voltage rating of up to 3,200 Vdc, depending on resistance value.

The RNV Series is available in both 5% and 1% tolerances, and in standard ammo and tape-and-reel packaging. The resistors are suited for applications requiring high-voltage-handling capability, high reliability, and high stability. Pricing for 1% tolerances is around $0.04 each in full-reel quantities.
