NTC THERMISTORSPECIFICATIONS

1)    Scope

This specification defines ratings, dimension, insulation, climatic test and mechanical characteristics for JT type thermistor.
2) Part No.:  DAE-JT103F-025

3) Rating

  3-1) Rated zero-power resistance  : R25 : 10KΩ ± 1% ( at 25℃ )

  3-2) B value : B25/85: 3,435K ± 1%

       * The B value is calculated using the zero-power resistance values measured at 25℃ and 85℃.

  3-3) Dissipation factor                 : Approx. 0.7 mW/℃ ( in air )

  3-4) Thermal time constant            : Approx. 5.0 S ( in air )

  3-5) Maximum power rating            : 2.5 mW ( at 25℃ )

  3-6) Category temperature range       : -40 ~ 90 ℃

4) Insulation resistance

    Insulation resistance shall be more than 100MΩ which is measured at DC 100V between film area and terminals.

 5) Climatic test

  5-1) Dry heat

       After the test samples were exposed in air at 90 ± 1℃ for 1,000 hours, the change ratio of the rated zero-power resistance shall be within ± 1%  of the initial value.

  5-2) Damp heat

        After the test samples were exposed in the humidity of 95% at 40 ± 2℃ for 1,000 hours, the change ratio of the rated zero-power resistance shall be within ± 1% of the initial value.

  5-3) Cold

       After the test samples were exposed in air at  -30 ± 1℃ for 1,000 hours, the change ratio of the rated zero-power resistance shall be within  ± 1% of the initial value.

  5-4) Loading

       After DC 1mA current was applied to the test samples in the temperature of 40 ± 2℃ and the humidity of 95% for 1,000 hours, the change ratio of the rated zero-power resistance shall be within ± 1% of the initial value.

  5-5) Change of temperature

       One cycle of the change of temperature shall be carried out in the order of the following conditions.

l      Room ambient temperature ( Initial value ) at -25 ± 3℃ for 30 minutes.

l      Room ambient temperature for 3 minutes at 90 ± 2℃ for 30 minutes

l      Room ambient temperature for 3 minutes after the 100 cycles of this process, the change ratio of the rated zero-power resistance shall be within ± 1% of the initial value.

 6) Mechanical characteristics

  6-1) Resistance to soldering heat

       The terminals shall be dipped into a soldering bath having a temperature of 260 ± 5℃ to a point 2.0mm from the body and then be held there for 5 ± 1s, the change ratio of the rated zero-power resistance shall be within  ± 1% of the initial value.

  6-2) Solderability

       After dipping the terminal to a depth in a soldering bath of 235  ± 5℃ for  ± 0.5s.  Approximately 90% of terminals should be covered with solder uniformly.

  6-3) Free fall:

       After three times fall to a maple board from 0.75 meter high, there shall be no visible damage and the change ratio of the rated zero-power resistance shall be within  ± 1% of the initial value.

  6-4) Robustness of termination
