ATB SERIES 175°C RATING
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 encapsu-
lated in moisture-proof epoxy. ATB 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%.
ATS SERIES 350°C RATING
RCD ATS 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 PTB Series temperature sensitive resistors offer the same
reliability and precision performance as the ATB series except in
a radial lead design.
