PTC Resettable Fuses are an important component of the modern electrical system. They are designed to protect the system from over-current and overloads, and they also act as a safety device to isolate any current beyond a certain level. The MF-S350 is an example of such a product, and it is widely used in a wide range of electrical applications. In this article, we will discuss the application field and working principle of MF-S350.

Application Field

The MF-S350 is used in many applications, including but not limited to:

• Automotive electronics.
• Industrial equipment.
• Medical devices.
• Consumer electronics.
• Communication products.
• Renewable energy.
• Building automation.

The MF-S350 is designed to be used in a variety of applications due to its high current rating, low resistance, and its ability to reset itself after a certain amount of over-current has been detected.

Working Principle

The MF-S350 works by using a positive temperature coefficient (PTC) thermistor. A PTC thermistor is a specially designed resistor which increases in resistance with increases in temperature. When the ambient temperature in the surrounding environment of the PTC rises, the resistance of the PTC increases to reduce the flow of current in the circuit. This helps to protect the circuit from over-current damage.

When the current rises beyond a certain predetermined level, the PTC thermistor trips the fuse, which interrupts the flow of current in the circuit. This prevents the failure of components that may be connected in the circuit. When the current drops to an acceptable level, the PTC thermistor will reset itself, allowing the circuit to be reconnected.

The MF-S350 is designed to help protect sensitive electronics and other equipment from dangerous and potentially harmful over-currents. The PTC thermistor is able to reset itself after an over-current has been detected, which helps to ensure that no further damage occurs. This makes the MF-S350 a very important part of any electrical system.

The MF-S350 is a reliable and robust PTC resettable fuse that is used in a variety of applications. Its working principle, which relies on the use of a PTC thermistor, makes the MF-S350 an effective and efficient tool for protecting sensitive electronics from the damaging effects of an over-current.
