Overview of 1812L075/33DR by Littelfuse Inc.
The 1812L075/33DR by Littelfuse Inc. is a Polyfuse resettable fuse designed with a PPTC (Polymeric Positive Temperature Coefficient) case style, measuring at 1812 (4532 metric). As a PTC resettable fuse, this component offers overcurrent protection with a unique ability to return to its low resistance state upon the removal of the overcurrent condition. It features a holding current of 750mA, a trip current of 1.5A, and a voltage rating of 33Vdc. The time to trip is remarkably quick at 0.2 seconds, accommodating a maximum current rating of 20A. This fuse is designed for surface mount installation (SMD) and adheres to environmental standards being halogen-free and RoHS compliant.
The device operates effectively across a wide temperature range from -40°C to 85°C, suitable for various challenging environments. Furthermore, the 1812L075/33DR is encapsulated in a chip-style package that is rectangular, with dimensions ensuring it is space-efficient and ideal for compact circuit board layouts. This component is also characterized by its resistance value, initially low at 0.11Ω, which increases when the fuse trips to help reduce the current flow and protect the circuit. The surface mount technology (SMT) facilitates simpler machine placement and more streamlined manufacturing processes.
