　　MF52 series NTC thermistor technical requirements

　　The MF52 series NTC thermistor is a small -sized NTC resistance chip painted from epoxy resin. It is made of new materials. It has a novel craftsmanship, high accuracy, fast response, and small volume. It is often made into a temperature sensor of various shapes by secondary processing, or is connected with the circuit as a surge current limiter. They are usually used for temperature control and instructions, and current suppression.

　　1. The MF52 series NTC thermistor is water droplets, and the closed mouth and the wire interface are neat and smooth, and the phenomenon of cracking without separation. The packaging site is smooth and round, with no bubbles and miscellaneous colors; the outer mold and wire of the joints are non -toxic and cold -resistant PVC, and the color is black. The color of the sensor packaging resin can follow the Pantone according to different requirements.

　　2. The packaging body and the wire are firmly bonded and can withstand tensile for more than 3.5kg.

　　3. Measurement of the product at different temperature points to meet the B value tolerance requirements of the NTC resistance.

　　4. 100%pitch test, there must be no short circuit, disconnection, and poor contact.

　　5. NTC chip welding rate (250 ℃/1sс.) ≤0.3%.

　　6. Thermal cycle impact test: Place the heat -sealing thermal resistance in the oil groove of 5min ← → 90 ° C in the oil groove of 5 min in -30 ° C. Essence

　　7. When the NTC resistance value is 25 ° C, the nominal resistance value is 2.252kΩ; at 37 ° C, the nominal resistance value is 1.3554 kΩ, the temperature is 30 ± 0.2 ° C, 35 ± 0.2 ° C, and 40 ± 0.2 ° C measurement measure The resistance value must be within the resistance range of the beta value of 3976 (25/85).

　　8. NTC thermist resistance accuracy must meet the characteristic standards, and all materials of the temperature probe are required to meet the ROHS standard.
