RCD A TS Series resistors offer precision wirewound resistor
performance at economical pricing. 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 ATB Series resistors of fer 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 encapsu-
lated in moisture-proof epoxy . A TB sensors meet the environ-
mental requirements of MIL-R-93. Operating temperature
range is -55°C to +175°C. Standard resistance tolerances are
±0.1%, ±0.25%, ±0.5%, ±1%.
