TG1.8.181J

The TG1.8.181J is designed as one kind of positive temperature coefficient silicon thermistor that is encapsulated in a glass, hermetically sealed package. The TM1/8 and TM1/4 thermistors are encapsulated in a molded package. Both have hot solder-dipped leads and are used in temperature sensing and compensation circuits.

Features of the TG1.8.181J are:(1)qualified to MIL-T-23648A;(2)TG1/8 - similar to RTH42 (MIL-T-23648A/19);(3)TM1/8 - similar to RTH22 (MIL-T-23648A/9);(4)large positive temperature coefficient = 0.7 %/;(5)wide resistance value ranges available in 5% or 10% tolerances.

The absolute maximum ratings of the TG1.8.181J can be summarized as:(1)power dissipation at (or below) 25 free-air temperature: 300 mW or 500 mW;(2)power dissipation at (or below) 100 free-air temperature: 125 mW or 250 mW;(3)operating free-air temperature range: -55 to +125 ;(4)storage temperature range: -65 to +150 .

The electrical an thermal characteristics of this device can be summarized as:(1)zero power resistance ratio: 0.55 +/- 15%;(2)thermal time constant - typical: 35 s;(3)thermal time constant - maximum: 60 s.
