PTC Resettable Fuses

PTC resettable fuses are a type of fuse designed to automatically reset and resume operation once the electrical problem that triggered the cut off is cleared. There are many models available in the market, but one of the popular and widely used models is the MF-SVS170N-0. It is a surface mount fuse with excellent operating performance and great reliability.

Application Field

The MF-SVS170N-0 is widely used in the computer, telecommunications, household appliances, and automotive industry. This device is usually used to protect electronics from minor voltage or current overloads during normal operation. It is usually mounted on a PCB, snapped onto a chassis, or mounted onto a capacitor, depending on the application. Besides that, the MF-SVS170N-0 is designed to protect equipment and ensure the safety of personnel in the case of an electric shock.

Working Principles

When the line current exceeds a certain threshold, the MF-SVS170N-0 will start to behave like a fuse and trip out. This model uses a two-terminal current-sensitive resistor (PTC) to sense the current in the line. When the current is greater than the rated value, the PTC heats up and generally increases resistance. This process trips the fuse and the current is immediately cut off before any damage is caused to the equipment or personnel. Once the current reduces, the PTC cools down and the fuse is reset. The device remains in the “safe” condition for the next use. This cycle of tripping and resetting can be repeated multiple times and can provide protection for a long period of time. The thermal cycling ensures that the lifetime of the device can be extended and it can remain in operation for the expected period of time.

Advantages

The MF-SVS170N-0 comes with several benefits that make it an attractive choice for many applications. For starters, this device is easy to install, maintain and use. It does not require an external power supply for operation, making it more energy-efficient and cost-effective. Additionally, this device can be used in applications where regular fuses cannot be used as it provides comprehensive protection for equipment and personnel. Since the fuse can be used multiple times, it saves on the cost of replacing the fuse. The operating temperature range is wide and can function in temperatures from -40C to 90C. Above all, this device is also RoHS compliant, ensuring that it is environment-friendly.

Conclusion

The MF-SVS170N-0 PTC resettable fuse is an extremely reliable device that can provide substantial protection for various types of equipment and personnel. It is widely used in the automotive, computer, telecommunications, and household appliances industry. Its ease of use, low cost of ownership and environmental-friendliness make it an attractive choice for many applications. With its superior performance and reliability, it is no wonder why this device is one of the most popular and widely used PTC resettable fuses in the market.
