MF-RX160-AP-99

PTC Resettable Fuses have been around for over a century, and are used in a huge variety of applications and industries. MF-RX160-AP-99 is a specific type of PTC Resettable Fuse that has a range of desirable applications and features that make it desirable in many applications.

PTC Resettable Fuse: Overview

PTC Resettable Fuses (aka Polymer Positive Temperature Co-efficient Resettable Fuses) are semiconductor devices that are designed to provide electrical protection against a variety of hazards such as over voltage, over current, and short-circuiting. The fuse is made up of two parts: a positive temperature co-efficient (PTC) element, and a negative temperature co-efficient (NTC) element, which act as check valves. The PTC element will only allow current to flow if it reaches a certain temperature, and the NTC element will limit the amount of current that can pass through the fuse when it reaches a certain temperature. The main advantage of PTC Resettable Fuses is that they are self-resetting and can be cycled multiple times. This makes them ideal for circuits where there is constant fluctuation in the electrical environment, as the resetting ensures that the circuit is always protected. They are also much more efficient than traditional fuses, as they do not need to be replaced every time a transient occurs.

MF-RX160-AP-99: Application Field and Working Principle

The MF-RX160-AP-99 is a type of PTC Resettable Fuse that is designed for use in a range of applications including consumer electronics, solar cells, and automotive electronics. It is a self-resetting fuse that has a two-pin design, and can be used in alternating current (AC) or direct current (DC) circuits. It is a compact design that is just 6.8mm by 6.8mm, and has a rated hold current of 0.160A.The working principle of the MF-RX160-AP-99 is similar to other PTC Resettable Fuses. When a circuit is operating at a safe level, the PTC element allows the circuit to remain in its current state, while the NTC element limits the amount of current which can pass through the fuse. During an over-voltage or over-current event, the temperature of the PTC element rises and reduces the current passing through the device. This acts as a protection mechanism, as it limits the amount of current that can be applied to the circuit. Once the thermal event has passed, the device will automatically reset itself, and will allow a safe amount of current to continue to flow through the circuit.

Conclusion

The MF-RX160-AP-99 is a type of PTC Resettable Fuse that is designed for use in a wide variety of applications. Its unique two-pin design and compact size make it ideal for applications where space is limited, and its self-resetting nature ensures that the circuit is always protected. The working principle of the MF-RX160-AP-99 is identical to other PTC Resettable Fuses, and ensures that overvoltage and overcurrents are always kept to a safe level.
