PTC resettable fuses serve as a safeguard to protect electrical equipment and components from unexpected surges, preventing damage to the device or system. These fuses utilize a small ceramic disc, known as a Polymer-Thin Film (PTF) resistor, to conduct a current. When the current exceeds a certain level, the PTF resistor will generate heat. This heat can either cause a non-conductive film to form on the resistor, or cause the resistor to separate mechanically. Should this happen, the circuit will be broken, preventing the flow of current and thus protecting the device or system from further damage.

The MF-SM200-2-99 is a type of PTC resettable fuse which can protect a variety of equipment from power surges or short circuits. It is rated for up to 2A at 250VAC and can handle a maximum of 16A at 250VAC momentarily. The device features low thermal resistance, fast thermal response, and high current interrupting capabilities, making it a suitable choice for a variety of applications. Additionally, the device has a small size that allows it to fit into tight spaces, making it suitable for a variety of different installations.

The MF-SM200-2-99 has a multitude of potential applications. It can be used in the protection of AC outlets, power supplies, printers, appliances, and other equipment. It can also be used in automotive, telecommunications, audio equipment, medical equipment, and industrial systems. Additionally, these devices can also be used in the protection of battery packs, LED lighting applications, and other high-end applications. By offering reliable surge protection, the device can help to prevent the loss and damage of expensive components and equipment caused by power fluctuations.

The working principle of the MF-SM200-2-99 PTC resettable fuse depends on the design of the PTF resistor. The resistor is designed in such a way that it will heat up when exposed to a certain level of current. This heat will then cause a non-conductive film or oxide layer to form on the resistor, or the resistor will mechanically separate which will cause an open circuit and therefore stop the flow of current. Once the source of the fault or surge is removed, the heat dissipates and the device will be reset and ready for service again.

The MF-SM200-2-99 PTC resettable fuse offers a reliable, efficient, and cost-effective way to protect your valuable electronic components and equipment from power surges or short circuits. By utilizing a PTF resistor, the device is able to generate heat when it is exposed to a certain level of current, which will then cause the circuit to be broken and prevent further damage from occurring. This device is suitable for a variety of applications, from AC outlets to high-end LED lighting systems, and can help to ensure the continued stability and performance of your systems.
