Available on exclusive SWIFT TM delivery program! Additional sizes available--most popular shown below Choice of 15 standard temperature coefficients per Table 1 RCD’s AT and PT Series resistors offer inherent wirewound reliability and precision performance in all types of temperature sensing or compensating circuits. Sensors are wound with various alloys to achieve wide range of temperature sensitivity. ATS SERIES 350°C RATING ATB SERIES 175°C RATING RCD ATS Series offer precision wirewound resistor performance at economical pricing. Ceramic core and silicone coating provide high operating temperature. The coating ensures maximum protection from environmental and mechanical damage (envir. performance per MIL-PRF-26). RCD ATB Series are typically multi-layer bobbin-wound enabling higher resistance values. Encapsulated in moisture-proof epoxy, Series ATB meets the environmental requirements of MIL-R-93. Operating temperature range is -55°C to +175°C. Standard tolerances are ±0.1%, ±0.25%, ±0.5%, ±1%.

Example: a resistor with a TC of +3200 ppm can be manufactured with a resistance value twice as high as the same resistor with a TC of 4500 ppm. A resistor with a TC of +6000 ppm can only reach a third of the resistance value available with 4500 ppm wire.
