Polymer Thick Film (PTF) resettable fuses are widely used in modern day electronics for protecting against overcurrent and short circuits, improving efficiency, and reducing component size. the FEMTOSMDC008F-02 is a PTF resettable fuse, deployed in a variety of devices across various industries.

The Application Field

FEMTOSMDC008F-02 is designed and manufactured to provide robust overcurrent and short circuit protection for automotive, consumer electronics, and energy management applications. It offers a superior level of protection in high-density PCBs of varying sizes. These devices are designed to continually monitors circuit current flow and helps to save on hardware space by featuring an ultra-low profile.

Automotive applications demand exceptionally robust circuit protection, and the FEMTOSMDC008F-02 helps meet these requirements by providing reliable, sinter-temperature thermal protection as well as excellent electrical insulation properties for even the most demanding environments. Additionally, the small size and low profile of this device make it an attractive choice for automotive applications requiring circuit protection that is both space-saving and reliable.

In consumer electronics, FEMTOSMDC008F-02 offers superior protection of battery packs, USB ports, and other components from damage caused by overcurrent and short circuits. Its ultra-low profile is advantageous in designing compact, high-density, and advanced applications. The device also provides excellent protection for microcontrollers, microelectronics, and mission critical devices.

The Working Principle

PTF resettable fuses like FEMTOSMDC008F-02 operate by actively monitoring the current flow in the circuit they are protecting. When the current exceeds the preset limit, a small resistor– the “polymer thick film element” – heats up to quickly open the circuit. This halts the current flow, thereby protecting against damage and preventing a fire.

Once the short circuit or overcurrent is eliminated, the device automatically cools and resumes its “off” position. This is known as a “reset cycle,” and it allows the PTF resettable fuse to be reused multiple times before requiring replacement. This makes the device an excellent choice for applications where resettable circuit protection is needed.

Conclusion

FEMTOSMDC008F-02 brings a great benefit to many automotive, consumer electronics, and energy management applications. This PTF resettable fuse, while compact size and ultra-low profile, offers superior protection against overcurrent and short circuits, ensuring a reliable, durable, and safe performance. It is also engineered to reset itself multiple times before needing to be replaced, making it cost-effective and highly reliable for a variety of applications.
