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 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
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.
