Negative Temperature Coefficient Thermistor Operating Temperature Range -30 ~ 110 °C

Scope

This specification defines ratings, dimension, insulation, climatic test and mechanical characteristics for MJT type thermistor


Climatic test

Dry Heat


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

Damp heat


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

Cold


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

Loading
After DC 1mA current is applied to the test samples in the temperature of 40±2°C 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.

Mechanical characteristics

1. Resistance to soldering heat
The terminals shall be dipped in to a soldering bath having a temperature of 260±5°C to a point 2.0 mm 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.

2. Solderability
After dipping the terminal to a depth in a soldering bath of 235±5°C for 2

±0.5s .Approximately 90% of terminals should be covered with solder

uniformly.


3. Free fall

After three times fall to a maple board from 0.75 m 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.

4. Robustness of terminations
After 1N loading weight for 10 ± 1s was applied to the wire 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.
