MINISMDC200F-2 application field and working principle

PTC Resettable Fuses: Overview

PTC resettable fuses, also known as polyswitch fuse, are popular components widely used in a variety of consumer electronics applications, from laptop adapters and automotive components to telecommunication equipment and other industrial circuits, to protect against surge overloading. They have been developed over many years, and the complexity of current resettable fuse technology is difficult to imagine. Resettable fuses use the self-restoration properties of polymeric devices with well established physical fundamentals in order to achieve excellent performance in current-limiting protection, safeguard and temperature compensation features. When exposed to an over-current, the polymeric part of the resettable fuse will become more ‘resistive’ with a gradual increase in electrical resistance. When the current reaches a predetermined level, it will open completely and the circuit will be interrupted. After the current drops to a lower predetermined value, the polymeric part will regain its original, low-resistance state, and the circuit can be restored. By using this loop of active resistance, the resettable fuse can accurately detect and protect against various kinds of over-currents and surge currents.

It can protect against over-currents as well as transient and surge currents, providing versatile and reliable protection for the user.Specifically, the MINISMDC200F-2 resettable fuse can be used in devices such as: laptops, adapters, batteries, circuit breakers, cell phones, power banks, electronic appliances, automotive components, biomedical implants, printer components, solar panels, computers, servers, and other industrial circuits.

MINISMDC200F-2: Working Principle

The MINISMDC200F-2 has a number of features that make it an ideal choice for providing over-current protection in a wide range of applications. It has a one-time trip current range of 0.60A to 8.00A and a repeat current performance of up to 200mA. This allows the resettable fuse to detect over-currents and surge currents quickly and accurately. The resettable fuse also has a positive temperature coefficient (PTC) that provides temperature compensation to ensure the fuse is operating within its specified parameters. The PTC also ensures the device does not reset prematurely. Furthermore, the MINISMDC200F-2 also has a “protection fault signal” output that allows users to monitor the devices status and condition in real-time. The MINISMDC200F-2’s is designed with a wide operating temperature range, which is -40°C to +125°C.. This makes it suitable for use in a variety of environmental conditions, from extremely cold to hot temperatures. The MINISMDC200F-2 is a robust resettable fuse that is designed to provide reliable protection against over-currents and surge current, as well as temperature compensation and real-time fault detection. It is suitable for use in a variety of applications, from consumer electronics to medical and industrial equipments.
