     (resistance and B value tolerance can be ±1%)

2.  High sensitivity,fast response,temperature resistance coefficient can be (2~5)%/℃ 

3.  High precise  temperature control,

4.  Can be encapsulated based on specific installation condition,convenient for users' installation

5.  Good insulation,anti bending and anti mechanical collision,high reliability


Dimension(Unit: mm):

Characteristic:

1.Product name: NTC temperature sensor

2.R25 resistance:R25=10KΩ±1%,

3.B value: B25/50=3950K±1%

4.Thermal response time:T1=25+(85-25)*63.2%=62.9℃ 8S Max.In a water bath

5.Dissipation coefficient:Ta=25±0.5℃ around 2.5mW/℃.In the still air

6.Hi-pot Test:AC 1500V 2mA 6 6S,no flashover ,no breakdown in steel ball

7.Insulation Test:DC 500V 100MΩ,≥100MΩin a steel ball

8.ERP:MF52C103F3950L27026AWG-NTS0822

9.Operating temperature:-30℃~105℃


Reliability test:

1. High temperature experiment: 1000 hrs in air 100 ± 5 °C

2. Low temperature experiment: -30 ± 5 °C 1000 hrs in air

3. Temperature cycle experiment: -30 °C / 30 minutes. Room temperature 10 minutes. 100 °C / 30 minutes 10 cycles

4. Electricity experiment: DCO 0.2 mA 1000 hrs in constant temperature and humidity

5. Lead strength: The force applied to 20N lasts 1 minute

6. Fall experiment: free fall of mud floor from 1M height

After the above performance test, there is no change in voltage resistance, insulation performance, and appearance without damage.


Storage Method:

1. No more than 4 boxes of products per stack height during storage and transportation;

2. Dry agent should be placed in the bag. Avoid direct or indirect showers and mechanical damage from rain and snow;

3. Products should be stored at room temperature and often wet, and the surrounding environment should not be acidic,

 alkaline substances and corrosive gases or radiation sources.
