Servei OEM/ODM de fusible tèrmic de tall SEFUSE NEC SF

Com saber si un fusible de temperatura NEC sefuse (Fusible tèrmic) és bo o dolent?
The following steps can be used to measure the quality of a temperature fuse (Fusible tèrmic) :

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, s'hauria de doblegar d'una part més que 6 mm de distància de l'arrel, and the root and lead should not be damaged. No estireu a la força, premsa, or twist the lead. ‌
Welding operation: En soldar el plom, la humitat de la calefacció s'ha de limitar al mínim, and be careful not to apply high temperature to the thermal fuse. No estireu a la força, premsa, o gireu el fusible tèrmic i el plom. Després de la soldadura, s'ha de refredar durant més de 30 segons immediatament.
Use conditions: Thermal fuses can only be used under the conditions of specified rated voltage, temperatura actual i especificada. Presta especial atenció a la temperatura màxima contínua que pot suportar el fusible tèrmic.

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. Normalment, 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, equips electrònics, and automobiles, it is very important to regularly check whether the thermal fuse is burned out.
