Wirewound Power Resistors Withstand Extreme Temperatures

The CCW series of ceramic-core, axial wirewound resistors from TT electronics IRC includes power ratings from 0.5 to 9 W and can handle temperatures to 275°C. These rugged resistors feature a welded construction and conformal coating. They also can withstand a voltage rating of up to 100 V, suiting them for a variety of high-volume power electronics applications, including industrial environments and commercial power supplies. Resistances range from 0.1 Ω to 1.5 kΩ, with standard tolerances of ±2%, ±5%, and ±10%. Temperature coefficients of resistance are as low as ±300 ppm/°C at values of 20 Ω or less. Operating temperature ranges from –55°C to 275°C.
