PTC Resettable Fuses are commonly used in electrical circuits to protect it from current overloads. The MF-R900-0-99 is a type of PTC Resettable Fuse that is designed for a variety of electronic products such as appliances, automotive, and telecommunications.
This PTC Resettable Fuse has a variety of features such as high current rating, low voltage drop, fast trip time, wide temperature range, and a wide operating voltage range. It is also UL approved and provides superior over-current protection.
The MF-R900-0-99 has two main applications. One is to provide over-current protection in electronic circuits, and the other is to protect against electrical faults. It is typically used in high current circuits such as automotive and telecommunication systems.
The working principle of a PTC Resettable Fuse is based on the phenomenon of self-heating. As the current running through the fuse increases, it begins to heat up due to the resistor inside the fuse body. As the temperature increases, the resistance of the resistor increases and causes the current to decrease, thus preventing further damage to the circuit or the components that are connected to the circuit.
Once the current has been reduced, the fuse cools down and its resistance returns to its original state. This allows the current to continue flowing through the circuit until it is reset manually. The reset can be done by pressing the button on the fuse or manually disconnecting the power supply from the circuit for a few minutes.
In summary, the MF-R900-0-99 is a PTC Resettable Fuse that is designed for a variety of electronic products such as appliances, automotive, and telecommunications. It offers a variety of features such as high current rating, low voltage drop, fast trip time, wide temperature range, and wide operating voltage range. Its working principle is based on the self-heating phenomenon, where the resistance of the resistor increases as the temperature rises, thus preventing further damage to the circuit or the components connected to it.
