The Littelfuse 1812L050/30PR is a PolySwitch resettable PPTC (positive temperature coefficient) overcurrent protection device designed for surface mount applications. It features a hold current of 500mA and a trip current of 1A, with a maximum voltage rating of 30V DC and a maximum interrupt current of 100A. Typical power dissipation is 800mW. The device offers low initial resistance of 150mΩ and a maximum post-trip resistance of 1Ω, ensuring minimal power loss during normal operation. The time to trip at 8A is 150ms, providing fast response to overcurrent events.
The 1812L050/30PR is housed in a standard 1812 (4532 Metric) concave package with a low profile of 1mm maximum thickness, making it suitable for space-constrained designs. It is compatible with high temperature soldering processes and is RoHS compliant, lead-free, and halogen-free. The operating temperature range is -40°C to 85°C.
Typical applications include plug-and-play protection for motherboards and peripherals, USB port protection, PCI cards, and game console port protection. The resettable nature of the PTC eliminates the need for fuse replacement after a fault event, reducing maintenance and downtime.
The hold current is 500mA at 25°C.
The maximum voltage is 30V DC.
The time to trip at 8A is 150ms.
It is available in a 1812 (4532 Metric) concave surface mount package.
The operating temperature range is -40°C to 85°C.
