PTC (Positive Temperature Coefficient) Resettable Fuses are a type of fuse with a temperature-sensitive, internal resistance element. This element is designed to regulate the amount of current allowed to flow through it. Once the resistor heats up above a certain level due to over-current, it will switch its state and limit the amount of current it passes. Unlike conventional fuses, PTCs can be reset after they have operated once and have returned to room temperature.

The MF-S350S Resettable Fuse is a standard PTC resettable fuse with an operating temperature range of -40°C to +85°C. It is designed for applications requiring high inrush current protection, as well as surge protection with fast response time and high cycle life. The device is a self-resetting circuit breaker with a very high trip current. It is very stable and has a low temperature coefficient, making it suitable for applications which may require temperature compensation.

The MF-S350S Resettable Fuse operates by relying on hot resistance of Leaded Neodymium Cobalt Boron (LNCB) compounds. This compound has a large temperature coefficient of resistance (TCR), which allows it to quickly detect any temperature variations and respond accordingly. The temperature coefficient and the hot resistance together provide the necessary safety and circuit protection. The resistance changes dramatically under a certain temperature, which triggers the device\'s actuation. The threshold temperature is typically around +85°C.

When the MF-S350S Resettable Fuse has been actuated, the current can no longer flow and it will remain in the open-circuit state until it has cooled down below the trip point. Once this has happened, the device will automatically reset and the current will resume, allowing the circuit to continue to operate. This resetting feature provides an extra layer of protection, ensuring that the circuit is not damaged by a single short circuit or overload.

The MF-S350S Resettable Fuse is an ideal choice for applications such as smart switches, air conditioners, toys, computer peripherals, automotive equipment, industrial equipment, and home appliances. It can also be used for protection against over-current, short circuit, overload, surge protection, and over temperature protection. This device is able to provide reliable circuit protection, fast response time, and high cycle life.

In summary, the MF-S350S Resettable Fuse is a reliable and versatile device which can be used in a variety of applications to ensure safe operation. With its hot resistance and high temperature coefficient, this device is able to quickly respond to temperature variations and automatically reset when needed. In addition, this device provides fast response time and higher cycle life, making it a great choice for all kinds of circuit protection applications.
