PTC Resettable Fuses have become increasingly popular in the market today due to their extremely high level of safety and reliability for overcurrent protection. The MINISMDC260F/16-2 is one such type of PTC resettable fuse and has been designed to provide overcurrent protection in a wide range of applications. This article will discuss the application fields and working principles of the MINISMDC260F/16-2.

Application Fields

The MINISMDC260F/16-2 is a 16V rated, 2A-rated, current-limiting polymeric positive temperature coefficient (PPTC) fuse that is designed to provide overcurrent protection in a wide range of applications. It is ideal for battery management systems, automotive applications, data line protection circuits, printers and scanners, and other high-current applications.

The design of the MINISMDC260F/16-2 includes a center-mounted NRV (non-resettable valve), which increases its current sensitivity and helps to minimize the effects of inductive loads. This makes it an ideal choice for sensitive applications as well as applications where a fast response time is necessary.

Working Principle

The working principle of the MINISMDC260F/16-2 is based on the thermo-magnetic circuit breaker principle. Its design includes a thermistor, which has a positive temperature coefficient (PTC) that will increase the resistance of the thermistor as the temperature increases. When the current passes through the thermistor, it produces heat and the thermistor’s resistance increases, thus reducing the current that can pass through the fuse.

If the current passing through the thermistor exceeds the safe limits, the heat produced by the thermistor’s resistance increases to a point where it triggers a thermal disconnection. This thermal disconnection opens the NRV, thus cutting off the current and protecting the circuit from overload conditions. Once the current drops below the safe limits, the NRV will reset and the fuse will operate normally.

The MINISMDC260F/16-2 has been designed to provide excellent overcurrent protection in a variety of applications. It is especially suitable for sensitive applications that require a fast response time and reliable performance. Thanks to its high level of safety and reliability, the MINISMDC260F/16-2 is an ideal choice for overcurrent protection.
