SEFUSE NEC SF Cutoffs Thermal Fuse OEM/ODM pakalpojums

How to tell if a sefuse NEC temperature fuse (Termiskais drošinātājs) is good or bad?
The following steps can be used to measure the quality of a temperature fuse (Termiskais drošinātājs) :

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, tas ir jāaizstāj.

The following matters need to be noted during the measurement process:
Lead bending: When bending the lead, tai jābūt saliektai no daļas vairāk nekā 6 mm attālumā no saknes, and the root and lead should not be damaged. Nevelciet ar spēku, nospiediet, or twist the lead. ‌
Welding operation: Metinot vadu, apkures mitrums jāierobežo līdz minimumam, and be careful not to apply high temperature to the thermal fuse. Nevelciet ar spēku, nospiediet, vai pagrieziet termo drošinātāju un vadu. Pēc metināšanas, to vajadzētu atdzesēt ilgāk par 30 sekundes uzreiz.
Use conditions: Thermal fuses can only be used under the conditions of specified rated voltage, strāva un norādītā temperatūra. Pievērsiet īpašu uzmanību maksimālajai nepārtrauktai temperatūrai, ko termiskais drošinātājs var izturēt.

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. Parasti, 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, elektroniskās iekārtas, and automobiles, it is very important to regularly check whether the thermal fuse is burned out.
