IRC's High Temperature Chip Resistors Rated for 200°C Operation



Special termination options make resistors ideal for extreme applications...

CORPUS CHRISTI, TX (May 2, 2006) - Providing design engineers with a resistor suitable for extremely high operating temperatures, TT electronics IRC Advanced Film Division has developed a series of tantalum nitride chip resistors 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.

According to Jerry Seams, Applications Engineering Manager for IRC's Advanced Film Division, the PFC-HT Series chip resistors were designed for use at extremely high temperatures such as down-hole oil drilling sensing equipment.

"In addition to designing the resistor itself for high-temperature operation, the challenge also included developing a method to attach to the PC board at such temperature extremes," said Seams. "The resistors are available with either 100% tin or gold-plated terminations that will not reflow at 200°C, enabling engineers to use epoxies and solders designed for high temperature applications."

In addition to the down-hole sensor measurement applications for which they were designed, Seams continued, the PFC-HT Series devices are also suitable for automotive engine compartment and aerospace applications.

Available in industry standard 0603, 0805 and 1206 chip sizes, the PFC-HT Series chip resistors have voltage and power ratings of 33.3V/62.5mW, 50V/100mW and 100V/125mW, respectively. Resistance range is from 10W to 85KW, with tolerances to ±1%. The resistors have absolute TCRs from ±25ppm/°C to 100ppm/°C, with an operating temperature range from -55°C to +200°C.

Pricing for the PFC-HT Series devices is $0.30 each in quantities of 10,000. Lead time is from stock to 8 to 9 weeks.
