PTC resettable fuses (positive temperature coefficient) are current-limiting devices that provide a safe and convenient means of electronic current protection. The 0805L200SLTHYR is a small, low profile, resettable fuse that has been specifically designed for SMD and/or low profile applications. This fuse operates by using a PTC thermistor device that has an intrinsic bimetallic element and is designed to act as an overcurrent circuit breaker.

In its normal state, the 0805L200SLTHYR fuse will allow the current to flow through it, just like any other type of fuse. When the current flows through the PTC thermistor exceeds a predetermined limit, however, the bimetallic element of the thermistor will heat up and expand, causing a resistance in the circuit. This resistance will restrict the current flow until it reaches the value of the rated holding current of the fuse, at which point the fuse will start to trip and will remain tripped until the current is reduced below the trip point.

The 0805L200SLTHYR fuse is commonly seen in automotive, electrical/electronic, industrial and consumer applications. In these applications, it is used as an overcurrent protection device to ensure that currents do not exceed the maximum value. This type of fuse is designed to be installed in tight spaces, so they are ideal for applications where space and/or cost constraints may be present. Since it is resettable, it provides a convenient means of resetting the circuit breaker if it trips for any reason. This type of fuse is also highly reliable, as it is constructed of highly durable materials that provide protection from wear and tear.

The working principle of the 0805L200SLTHYR fuse is simple. When the current exceeds the preset trip point, the PTC thermistor will heat up and expand, thereby increasing its resistance. This resistance will cause the current to drop to the rated holding current of the fuse and the fuse will then be tripped. If the current is reduced to below the trip point, the fuse will reset itself and the current flow will be restored. This makes it an ideal choice for circuit protection due to its efficiency and accuracy.

The 0805L200SLTHYR fuse is a reliable, efficient and cost-effective solution for electrical current protection and offers numerous advantages when compared to traditional fuses. It is small, has a low profile and is resettable, allowing for resetting of the fuse if it is ever tripped. It is also highly durable and reliable, making it suitable for a variety of applications. In summary, the 0805L200SLTHYR fuse is an ideal choice for electronic protection due to its accuracy, reliability and cost-effectiveness.
