PTC Resettable Fuses are an important component within electronic circuits. As they are reusable and can be programmed for a variety of different elements and parameters, they are an integral element of modern technology.

The MF-RX185-2-99 is a polymeric resettable fuse designed as a resettable device for a variety of applications, ranging from automotive, consumer and industrial markets. The MF-RX185-2-99 is designed to provide effective protection against over-currents in the circuit, preventing damage from hard short-circuits or faults.

The MF-RX185-2-99 uses a combination of heaters and resistors designed to reset and resume protection from over currents. The heaters dissipate heat to slow down the melting of the resistor at higher temperatures, while the resistors themselves control the current levels. This combination allows for the fuse to achieve both a low impedance and high voltage rating, which results in a low internal resistance.

The working principle of the MF-RX185-2-99 is based on a positive temperature coefficient (PTC) switch on a parallel circuit. The PTC switch is designed to trip at a certain temperature, usually around 175°C, and when tripped interrupts the flow of current through the circuit. This prevents further current from flowing and restricts over-current.

The MF-RX185-2-99 can be used in a variety of applications, including power supply protection, motor control circuits, automotive equipment, and consumer electronics. The fuse can also be used for high-current applications such as in high-power LED lighting systems, power tools, and electric vehicles. The elements of the MF-RX185-2-99 allow it to be programmed to a wide range of current and voltage ratings for different applications.

The MF-RX185-2-99 offers a range of thermal protection features, including the ability to sense temperature and self-resettable properties, making it suitable for use in a variety of applications. It also provides a wide range of current and voltage ratings, allowing it to be used in various circuitry applications.

In conclusion, the MF-RX185-2-99 is an effective resettable fuse which provides protection for electronic circuits, preventing damage from over-currents and short-circuits, as well as providing thermal protection in a range of applications. The ability to program the elements of the fuse for different applications, combined with its low internal resistance, makes the MF-RX185-2-99 an ideal choice for applications ranging from consumer electronics to high-power LED lighting systems.
