PTC (Positive Temperature Coefficient) Resettable Fuses are devices engineered to provide overcurrent protection. The MF-USMF020-2 is a two-pack resettable fuse from the complete range of Resettable Fuses offered by the company. This device is an appropriate current protect component, which features robust durability and optimized heat dissipation. It is ideal for use in various types of electronic equipment, including consumer electronics.

This MF-USMF020-2 resettable fuse features a low resistance design and a low self-discharge current. The device is available in two resistance ranges, each consisting of four different values. The 1.5A resistance range offers a resistance value of 0.02Ω at a current of 5A, while the 2A resistance range offers a resistance value of 0.2Ω at a current of 10A. The device is designed to be compatible with both surface mount and through-hole mounting options.

The working principle of the MF-USMF020-2 is based on the phenomenon of electrical resistance. When the device is used in an overcurrent situation, the electrical resistance in the device will increase, resulting in the temporary interruption of the power supply to the application. By interrupting the power supply, the device prevents the application from experiencing any physical damage as a result of an overcurrent. Once the device cools down, the resistance will decrease, allowing the power supply to be restored.

One of the main applications of the MF-USMF020-2 is in the protection of sensitive electronic devices. As the device is designed to automatically switch off power supply when an overcurrent is detected, this prevents physical damage from occurring in sensitive electronic components. The device can also be used to provide protection against voltage surges in an application, such as providing protection during a power outage. Finally, the device can also be used to protect against short circuits, as the device will automatically open the circuit when an overcurrent is detected.

The MF-USMF020-2 is a reliable and cost-effective way to protect sensitive electronic components from the damage caused by overcurrent or additional voltage surges. The device features a low resistance design and is compatible with both surface-mount and through-hole mounting options. The device is ideal for use in a wide range of applications, including consumer electronics and communication systems.
