Chip Resistors Operate To 200°C

A series of tantalum nitride chip resistors from TT electronics’ IRC Advanced Film Division is rated for operation at 200°C. Designated the PFC-HT Series, the chip resistors utilize IRC’s proprietary TaNFilm self-passivating resistive element technology, and feature a wraparound non-leaching termination style, with either gold-plated or 100% tin (lead-free) versions specifically designed to enable the devices to operate at elevated temperatures.

The PFC-HT Series chip resistors offer voltage and power ratings of 33.3 V and 62.5 mW, 50 V and 100 mW or 100 V and 125 mW. The resistance range is from 10 W to 85 kW, with tolerances to ±1%. Furthermore, the resistors have absolute TCRs from ±25 ppm/°C to 100 ppm/°C with an operating range from -55˚C to +200˚C. Available in 0603, 0805 and 1206 chip sizes, the resistors are priced at $0.30 each in quantities of 10,000.
