SEFUSE NEC SF atjungimai terminio saugiklio OEM/ODM paslauga

Kaip sužinoti, ar neveikia NEC temperatūros saugiklis (Šilumos saugiklis) yra geras ar blogas?
The following steps can be used to measure the quality of a temperature fuse (Šilumos saugiklis) :

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, it should be bent from a part more than 6 mm atstumu nuo šaknies, and the root and lead should not be damaged. Do not forcibly pull, paspauskite, or twist the lead. ‌
Welding operation: Suvirinant laidą, the heating humidity should be limited to a minimum, and be careful not to apply high temperature to the thermal fuse. Do not forcibly pull, paspauskite, arba pasukite šiluminį saugiklį ir laidą. 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, current and specified temperature. Ypatingą dėmesį atkreipkite į maksimalią nuolatinę temperatūrą, kurią gali atlaikyti šiluminis saugiklis.

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. Paprastai, 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, elektroninė įranga, and automobiles, it is very important to regularly check whether the thermal fuse is burned out.
