Resettable Fuse Manufacturing
Resettable fuse is my company's own development of over-current protection components, my company am using the high molecular organic polymer at a high pressure, high temperature, vulcanization reaction conditions, adding conductive particles doped material, Manufactured through a special process. The basic steps include: weighing, mixing, dehydration drying, (dry press made into a round, rectangular, round, honeycomb blank) aging, testing and testing process. encapsulated with flame retardant epoxy or polyester film conforming to UL94V-0 or IEC95-2-2. you can customize your desired product parameters. by reading our different product manufacturing services, learn how we can ensure product quality standards, please contact us for quotation or free samples.
What Is Resettable Fuse?
The resettable fuse is an overcurrent protection element that replaces the normal current fuse and can be automatically reset after disconnection. Resettable fuse is made of a polymeric material filled with carbon black particles, this material has a certain conductivity, thus being able to pass the rated current. if the current through the resettable fuse is too high, its heating power is greater than the cooling power, at this point the temperature from the recovery fuse will begin to rise, while the polymer matrix in the resettable fuse begins to expand, this will separate the carbon black particles, and lead to resistance rise, thus very effectively reducing the current in the circuit.
Resettable Fuse Characteristics
1, Because the polymer PTC resistance is recoverable, and thus can be repeated multiple use
2, Polymer PTC thermistor can be used for computers and their external equipment, mobile phones, battery packs, telematics and network equipment, transformers, industrial control equipment, automotive and other electronic products, there are over-current or over-temperature protection.
3, Polymer PTC thermistor and ceramic PTC thermistor is the difference between the initial resistance, action time and size difference. polymer PTC thermistor size is smaller, lower resistance, while faster response.
4, Storage time is long.
5, PTC thermistor can be used in parallel, advantage is to reduce the resistance and increase the holding current.
Resettable Fuses Of Different Sizes Sealed
