RNCP Series High Power Thin Film Resistors Stackpole Electronics RNCP Series High Power Thin Film Resistors offer a tolerance rating to ±0.1%, a TCR as low as 10ppm/°C, and an anti-sulfur design. RNCP resistors feature higher power ratings than standard thick film chips and have an inner termination engineered to deter sulfur contamination. Stackpole Electronics RNCP Series Resistors provide up to a 1W maximum power rating, 50V to 200V maximum working voltage range, and a 100V to 400V maximum overload voltage range.
