PTC Resettable Fuses

PTC resettable fuses, also known as PolyFuse® or Positive Temperature Coefficient (PTC) resettable fuses, are a particular type of fuse that are becoming increasingly popular in the electronics industry. PTC resettable fuses offer an excellent solution for providing overcurrent protection in a wide range of electronic devices and circuits. The main advantages of PTC resettable fuses are that they are easy to install, less bulky than traditional fuses, and provide improved overcurrent protection.The MF-RG800-0 is a PTC resettable fuse that is often used in applications such as mobile phones, PDAs, notebook computers, laptops, digital audio players, power supplies, and medical devices. This device offers excellent options for a range of overcurrent protection needs.The MF-RG800-0 connector features a one-piece, single-pole, single-throw (SPST) design with an operating temperature range of -20 to 85 ºC. The device’s maximum DC current handling is 800 mA and its maximum activating current is 200 mA, while the maximum hold current is 150 mA.The MF-RG800-0 fuse features a unique self-healing type of design that is capable of automatically resetting itself when the fault current drops below the hold current. This makes it an ideal choice for applications that require reliable and consistent overcurrent protection.The working principle of the fuse is based on the intrinsic characteristics of PTC devices, which feature a unique property of increasing resistance when heated. When the current passing through the device exceeds a certain threshold, the device\'s resistance increases sharply, effectively forcing the fault current to divert from the main circuit and protect the device or circuit against damage. The high resistance state will remain until the temperature of the device drops below a certain level, which will cause the resistance to decrease and the device to reset itself.The MF-RG800-0 fuse is a reliable and cost-effective solution for applications that require overcurrent protection. This device has a wide range of applications where reliable overcurrent protection is critical to ensure the safe and reliable operation of the device or circuit.
