Epoxy-Coated Temp Sensor

Insulation resistance

Insulation resistance shall be more than 100 MΩ which is measured at
DC500V between film area and terminals.

Climatic tes
1) Dry Heat
After the test samples were exposed to air at 90 ±2 ℃ for 1,000 hours, the change ratio of the rated zero-power resistance shall be within ±1% of the initial value.
2) Damp heat
After the test samples were exposed to 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.
3) Cold
After the test samples were exposed to air at –55 ±3℃ for 1,000 hours, the change ratio of the rated zero-power resistance shall be within ±1% of the initial value.
4) Loading
After DC 1mA current was applied to the test samples at a temperature of 40 ±2℃ and a humidity of 95% for 1,000 hours, the change ratio of the rated zero-power resistance shall be within ±2% of the initial value.
5) Change of temperature
One cycle of the change of temperature shall be carried out in the order of the following conditions.
.Room ambient temperature. (Initial value)
.At –25 ±3℃, for 30 minutes.
.Room ambient temperature, for 3 minutes.
.At + 90 ±2℃, for 30 minutes.
.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.

Mechanical characteristics
1) Resistance to soldering heat
The terminals shall be dipped into a soldering bath having a temperature of 260 ±5℃ 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℃ for 2 ±0.5s.Approximately 90% of terminals should be covered with solder uniformly.
3) Free fall
After three times falling 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.
