    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

           After 1N loading weight for 10  ± 1S was applied to the wise terminations, there shall be no visible damage and the change ratio of the rated zero-power resistance shall be within  ± 1% of the initial value.
