Ceramic core and silicone coating result in the high operating temperature range. The coating provides maximum protection from environmental and mechanical damage (environmental performance per MIL-R-26). RCD Type Body Body Lead Max. Watts Length Diameter Diameter 4500ppm @ 25C .031 [.787] .015 [.381] (Max.) Resistance RCD ATB Series resistors offer wirewound reliability and precision performance in all types of temperature sensing or compensating circuits. ATB sensors are wound with various alloys of temperature sensitive resistance wire and encapsulated in moisture-proof epoxy. ATB sensors meet the environmental requirements of MIL-R-93. Operating temperature range is -55C to +175C. Standard resistance tolerances are 0.1%, 0.25%, 0.5%, 1%. RCD Type Body Length .031 Body Diameter .015 Lead Diameter (Max.)
