Boone, N.C. TT electronics IRC Wire and Film Technologies Division delivers power and wirewound resistors that operate up to 275 degrees C for high-volume applications. Both the CAW series of wirewound resistors and CAF series of film resistors feature power ratings of 2 to 10 watts.
Aimed at general-purpose, high-volume applications, both types of resistors are enclosed in a flameproof ceramic case with inorganic fill materials, which makes them suitable for operation in extreme temperatures such as industrial and appliance applications. Other applications include power electronics circuits, voltage dividers, power supplies, and motor controllers.
The CAW series offers a resistance range from 0.1 ohm(Ω) to 1.2 KΩ, while the CAF series film resistors feature a resistance range of 28Ω to 200 KΩ. Standard tolerances for both devices are ±5% and ±10%, with temperature coefficient ratings (TCRs) of ±400 ppm/°C at less than 20Ω and ±350 ppm/°C at 20Ω and above. The operating temperature range is -55°C to +275°C. Custom specifications are available.
Pricing: Typical pricing for the CAW and CAF series resistors is $ .065 each for the 5-watt devices and $.15 each for the 10-watt devices in quantities of 10,000.
Delivery: Lead time is from stock to eight weeks.
