SEFUSE NEC SF Cutoffs Termiese Sekering OEM/ODM-diens

Hoe om te weet of 'n sefuse NEC temperatuur lont (Termiese lont) goed of sleg is?
The following steps can be used to measure the quality of a temperature fuse (Termiese lont) :

Use a multimeter to measure the resistance value: Set the multimeter to the resistance value measurement position, and then connect two test pens to the two ends of the Thermal Fuse . If the fuse is not blown, its resistance value should be very small. If the fuse is blown, the resistance value will be a larger number. If you are not sure about the correct resistance value, you can refer to the product manual or consult the manufacturer. ‌

Observe the color change: If the Thermal Fuse turns black or the resistance value is abnormally high, it needs to be replaced.

The following matters need to be noted during the measurement process:
Lead bending: When bending the lead, dit moet gebuig word van 'n deel meer as 6 mm weg van die wortel af, and the root and lead should not be damaged. Moenie met geweld trek nie, druk, or twist the lead. ‌
Welding operation: Wanneer die lood gesweis word, die verwarming humiditeit moet beperk word tot 'n minimum, and be careful not to apply high temperature to the thermal fuse. Moenie met geweld trek nie, druk, of draai die termiese lont en lood. Na sweiswerk, dit moet vir meer as afgekoel word 30 sekondes onmiddellik.
Use conditions: Thermal fuses can only be used under the conditions of specified rated voltage, huidige en gespesifiseerde temperatuur. Let veral op die maksimum deurlopende temperatuur wat die termiese lont kan weerstaan.

Additional suggestions and common problems:
Replacing fuses: When a thermal fuse burns out, it needs to be replaced with a new fuse with the same voltage and rated temperature. Gewoonlik, thermal fuses are designed to be push-pull, so you only need to gently pull out the old fuse and insert the new one.
Regular inspection: When using electrical appliances, elektroniese toerusting, and automobiles, it is very important to regularly check whether the thermal fuse is burned out.
