NTC Sensor1) SCOPE
This specifications define ratings, dimension, insulation, climatic tests and mechanical characteristics for TA type thermistor.

2) PART NO.: 103TA-4-26070-3950-1P

3) RATING
3-1) Rated zero-power resistance R25   : 10 kΩ ±1 % (at 25℃)
3-2) B value. B25/50 : 3,950K ±1 %
*The B value is calculated using the zero-power resistance values
measured at 25℃ and 85℃.
3-3) Dissipation factor.      :Approx.   2   mW/℃(in air)
3-4) Thermal time constant. :Approx.   15  s     (in air)
3-5) Maximum power rating.   :         10  mW   (at 25℃)
3-6) Category temperature range :       -30 to 80   ℃
(=Operating temperature range) 

4) DIMENSIONS   UNIT:[mm]

ntc sensor dimension

5) Insulation (between epoxy resin and soldered terminals)
5-1 Dielectric withstanding voltage: AC 100V for one second.
5-2 Insulation resistance        : Above 100 MΩ at DC 500V.

6) Climatic tests
6-1) Dry Heat
After the test samples were exposed in air at 80 ℃ for 1,000 hours, the change ratio of the rated zero-power resistance shall be within ±1% of the initial value.

6-2) Damp heat
After the test samples were exposed in the humidity of 95% at 40℃ for 1,000 hours, the change ratio of the rated zero-power resistance shall be within ±1% of the initial value.

6-3) Cold
After the test samples were exposed in air at -30℃ for 1,000 hours, the change ratio of the rated zero-power resistance shall be within ±1% of the initial value.

6-4) Humidity load

After DC 1mA current was applied to the test samples in the temperature of 40℃ 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.

6-5) Change of temperature
One cycle of the change of temperature shall be carried our in the order of the following conditions.
.Room ambient temperature.( Initial value)
.At -30℃, for 30 minutes.
.Room ambient temperature, for 3 minutes.
.At + 90℃, for 30 minutes.
.Room ambient temperature, for 3 minutes.
After 100 cycles of change of temperature, the change ratio of the rated zero-power resistance shall be within ±1% of the initial value.

7) Mechanical characteristics
7-1) Robustness of terminations
* Tensile to horizontal direction
Hold the thermistor body so that lead wire shall be horizontal. After 1 kg loading weight was applied to the lead wire horizontally for 10 seconds, there shall be no visible damage.

7-2) Free fall 
After three times natural fall to a maple board from 75cm high, there shall be no visible damage.

8) R-T characteristics
