PTC Resettable Fuses are used in many applications, with the LTP340 being one of the most common. It is a three-terminal, self-reset thermal fuse with superior current-limiting performance. As a resettable fuse, the device is designed to protect any sensitive electronics from overcurrent conditions. In addition, the device features an adjustable current limit setting, which can be precisely set to match the needs of the application.

The LTP340 is designed with an active PTC element and a thermal circuit breaker inside the package. It is suitable for a range of DC and AC powered applications. Its wide operating temperature range (from –55°C to +125°C) makes it ideal for applications with extreme temperature environments. It also works well in hostile environmental conditions.

The LTP340 is very simple in operation. The thermal circuit breaker inside the package is pre-calibrated to the desired current limit. In an overcurrent situation, the circuit breaker will trip and the PTC element will increase its resistance, preventing any further current flow. When the circuit cools down and the temperature goes back to its normal level, the circuit breaker will reset and the PTC element\'s resistance will drop, allowing the device to reset and safely allow for current flow again.

The LTP340 is available in a wide range of package sizes to accommodate different power requirements. In addition, its low thermal impedance ensures a rapid thermal response and fast reaction time, making it well-suited for high-frequency applications. This also ensures better temperature stability for better control and safety.

The LTP340 proves to be a versatile and reliable thermal protection solution for a variety of consumer electronics, automotive, industrial and medical applications. Its adjustable current limit setting helps protect sensitive electronics from overcurrent situations, while its low thermal impedance ensures fast thermal response times and improved operator safety. With its wide temperature range and durability, the LTP340 is an ideal choice for a wide range of circuit protection needs.
