Chip resistors handle the heat
IRC Advanced Film Division has developed a series of tantalum nitride chip resistors rated for operation at 200C.
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 200C Designated the PFC-HT Series, the chip resistors use IRC's proprietary TaN film self-passivating resistive element technology, and feature a wraparound nonleaching termination style, with either gold-plated or 100% tin (lead-free) versions specifically designed to enable the devices to operate at elevated temperatures

Resistors provide better surge protection
IRC Advanced Film Division has introduced a series of wire bondable chip resistors.
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 200C, 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 10ohm to 85kohm, with tolerances to +/-1%.
The resistors have absolute TCRs from +/-25 to 100ppm/C, with an operating temperature range from -55 to +200C.
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.
