PTC Resettable Fuses

PTC resettable fuses are a type of circuit protection device that is used to prevent damage to electronic components due to over-current conditions or overloads. The acronym PTC stands for Positive Temperature Coefficient; these fuses consist of a high resistance conductor in the form of a film or ceramic disk with a temperature-sensitive material usually in the form of a small piece of metal. When current exceeds the safe threshold, the PTC resettable fuses will automatically open the circuit and protect the surrounding component. After the problem has been corrected, the PTC fuse can then be manually reset and the circuit restored.

MF-PSML200-2 is a positive temperature coefficient (PTC) resettable fuse with a rating of 200V and 2A. The product features a robust and compact structure with high current and voltage capacity; it has excellent resistance to surge current and can provide circuit protection against over-current conditions and overloads. Its working principle is based on the phenomenon of weak self-heating. When the current flows through the fuse element (usually a copper wire), the wire heats up and changes the material property. This increase in temperature causes the element to form an open circuit, thus protecting the connected device from damage due to overloads.

The MF-PSML200-2 is ideal for a wide range of applications including automotive, computers, consumer electronics, telecommunications, and industrial control equipment. This type of PTC fuse can be used as a primary protection device to protect against over-current and overload, or as a secondary protection device to provide isolation in the event of an open circuit. It is capable of withstanding high inrush currents such as those associated with charging systems and power supplies. Additionally, thanks to its small size, the MF-PSML200-2 can be fitted into confined spaces without impacting the overall design.

In addition to its inherent benefit of providing reliable protection for electronic components in over-current conditions, PTC resettable fuses are also considered to be more environmentally friendly compared to more traditional fuses. This is due to the fact that traditional fuses, once blown, must be replaced and discarded, thus leading to increased pollution and waste of resources. PTC resettable fuses, on the other hand, can be reset multiple times, thus eliminating the need to purchase and discard new fuses every time a circuit protection device is needed. This makes them both economical and eco-friendly.

The MF-PSML200-2 is a highly reliable and robust PTC resettable fuse suitable for a wide range of applications. It is capable of providing robust protection against over-current conditions or overloads and is highly resistant to surge currents. It also features a small size, making it well-suited for confined spaces. In addition, it is an environmentally friendly choice as it can be reset multiple times without the need to purchase and discard new fuses. Thanks to all of these qualities, the MF-PSML200-2 is an ideal choice for many different types of applications.
