SEFUSE NEC SF Termalni osigurač za OEM/ODM servis

Kako znati je li sefuse NEC temperaturni osigurač (Toplinski osigurač) je dobro ili loše?
The following steps can be used to measure the quality of a temperature fuse (Toplinski osigurač) :

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, treba ga zamijeniti.

The following matters need to be noted during the measurement process:
Lead bending: When bending the lead, treba ga savijati od dijela više od 6 mm od korijena, and the root and lead should not be damaged. Ne povlačite na silu, pritisnite, or twist the lead. ‌
Welding operation: Kod zavarivanja olovo, vlagu za grijanje treba ograničiti na minimum, and be careful not to apply high temperature to the thermal fuse. Ne povlačite na silu, pritisnite, ili zavrnite toplinski osigurač i vodite. After welding, it should be cooled for more than 30 seconds immediately.
Use conditions: Thermal fuses can only be used under the conditions of specified rated voltage, trenutna i navedena temperatura. Obratite posebnu pozornost na maksimalnu trajnu temperaturu koju toplinski osigurač može izdržati.

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. Obično, 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, electronic equipment, and automobiles, it is very important to regularly check whether the thermal fuse is burned out.
