LTP100SSF

PTC Resettable Fuses

PTC resettable fuses are an important component of electrical equipment, providing protection against over-currents in circuits. The LTP100SSF is a type of PTC resettable fuse, used to protect against damage caused by over-currents in small electronic circuits. The fuse is suitable for a wide range of commercial, automotive, and industrial applications.

Application Field

The LTP100SSF resettable fuse is suitable for a range of applications, including: automotive electronics, consumer electronics, communication systems, battery packs, power management systems, industrial machinery, and medical equipment. It is also suitable for applications where high levels of surge protection are required. The fuse is specifically designed for automotive and consumer electronics, providing protection against over-currents, surges, and voltage transients.

Working Principle

The working principle of the LTP100SSF resettable fuse is based on a Positive Temperature Coefficient (PTC). When the PTC is subjected to an over-current, it will heat up, causing its resistance to increase. This will cause the current across the fuse to drop, thus protecting the circuit. When the over-current is removed, the PTC will begin to cool down and its resistance will return to its original value, reinstating the circuit. This cycle can be repeated many times, making the LTP100SSF a reliable, cost-effective way to protect circuits from over-currents.

Protection Features

The LTP100SSF resettable fuse has several important protection features. It provides circuit protection against over-currents of up to 100A, and has a built-in thermal cutoff, which will shut off the circuit if it detects an excessively high temperature. It also has an internal pressure monitoring system, which will detect excessive pressure within the fuse and shut off the circuit if necessary. The fuse also has a temperature range of -40°C to +135°C, making it suitable for a range of temperatures.

Conclusion

The LTP100SSF resettable fuse is an important component of many commercial, automotive, and industrial applications. It is based on a Positive Temperature Coefficient, meaning that it will heat up when exposed to over-currents, reducing the current flowing through the circuit and protecting it from damage. The fuse also has several protection features, including a thermal cutoff and an internal pressure monitoring system. This makes the LTP100SSF an effective, reliable, and cost-effective way to protect circuits from over-currents.
