PTC resettable fuses are an active electronic overcurrent protection device that are used to protect electric circuits against damage due to overcurrents and short-circuits. It is a two-pin device whose current carrying capacity is fixed and limited to maximum current under normal working conditions. When the current exceeds the specified threshold, the device will automatically switch off, thereby preventing further damage to the circuit.

The MF-R500-2-99 is a two-pin PTC resettable fuse developed by Vexta Corporation in Japan. It is encapsulated in a robust black plastic housing for additional protection. The device is rated for a maximum of 500mA and a maximum voltage of 30V. It features an Over temperature Current Protection (OTCP) which disconnects the power if the temperature exceeds the specified threshold. The device is suitable for applications such as AC/DC adapters, printer and laptop chargers, portable media players, gaming systems, and other consumer electronics.

The working principle of the MF-R500-2-99 is simple and straightforward. It features a precision temperature sensor and a thermistor. When the load current exceeds the specified threshold, the temperature sensor senses the rise in temperature and initiates the thermal cutoff process. The thermistor then trips, disconnecting the power supply and resetting the fuse. After the device has cooled down sufficiently, it can be reactivated and the circuit can be used again as normal.

The MF-R500-2-99 is an important device for a wide range of applications. Its resetting capabilities make it especially useful for protection sensitive electronic devices. Its low cost and easy installation make it an attractive option for many electric circuit protection needs.
