RTH22

The RTH22 thermistor is encapsulated in a glass,hermetically sealed package.Both hot solder-dipped leads and are used in temperature sensing and compensation circuits.Features of the RTH22 are:(1)qualified to MIL-T-23648A;(2)TM1/8-similar to RTH22;(3)large positive temperature coefficient 0.7%/;(4)wide resistance value range available in 5% or 10% tolerances.

The absolute maximum ratings of the RTH22 can be summarized as:(1):the parameter is power dissipation at (or below) 25 free-air temperature,the rated value is 500,the unit is mW;(2):the parameter is power dissipation at (or below) 100 free-air temperature,the rated value is 125,the unit is mW;(3):the parameter is operating free-air temperature range,the rated value is -55 to +125,the unit is ;(4):the parameter is storage temperature,the rated value is -65 to +150,the unit is .

The electrical and thermal characteristics of the RTH22 can be summarized as:(1):the parameter is zero power resistance ratio,the rated value is 0.55±15%;(2):the parameter is thermal time constant-typical,the rated value is 35,the unit is s;(3):the parameter is thermal time constant-maximum,the rated value is 35,the unit is s.
