PTC Resettable Fuses, also known as Polymeric Positive Temperature Coefficient Resettable Fuses, are protection components used in many electronic circuits. They are suitable for applications such as those which require a high level of protection from overcurrent or overvoltage events. The MF-RX300-005 is a resettable fuse specifically designed for such applications.

The MF-RX300-005 is a small, lightweight and cost-effective fuse which provides protection for circuits from overcurrent and overvoltage events. It has a hold-down tab which resets after an overcurrent event, making the fuse suitable for use in multiple applications. It is capable of switching between two states during normal operation: an ON-state where it permits current to flow and an OFF-state where it shuts off power when an overcurrent event occurs.

The working principle of the fuse is simple; when an overcurrent or overvoltage event occurs, the device heats up and the PTC element inside will expand, causing the circuit to be opened. The temperature of the device can reach up to 120°C before melting, ensuring that the device will protect the circuit from potential overvoltage and overcurrent events. The resetting process occurs when the temperature decreases and the device returns to its normal ON-state. This process can occur multiple times in a single day if necessary.

The MF-RX300-005 is widely used in applications such as consumer electronics, automotive electronics, telecommunications and instruments. It is commonly used to provide overcurrent protection for AC/DC circuits, batteries and other sensitive components. It is also suitable for automotive applications such as engine start circuits, fuel injection systems and ABS systems. In the field of telecommunications, the MF-RX300-005 is used to protect circuits from electrical spikes and surges. Other applications include power supply and medical equipment.

The MF-RX300-005 is a highly durable component which is designed to protect circuits from overcurrent and overvoltage events. It has a low trip-time and fast reset time, ensuring that the circuit will be protected in the event of an overcurrent or overvoltage event. The device is also highly reliable and has a long life-span, making it a cost-effective solution for protection in a variety of applications.
