Make sure to verify specifications such as hold current, trip current, and voltage rating to ensure compatibility with your application.

The part number 045106.3MRL refers to a specific type of surface-mount fuse from Littelfuse, part of the 451 Series NANO²® Slo-Blo® Surface Mount Fuses. These fuses are designed for circuit protection in various electronic devices.
- Pin Count: The 045106.3MRL typically has a 2-terminal configuration as it is a fuse, which is primarily a 2-pin component.
- Function: The function of the 045106.3MRL fuse is to provide overcurrent protection. It is designed to open (or "blow") and interrupt the circuit if the current flowing through it exceeds a specified limit (in this case, 6.3A), thereby protecting other components in the circuit from damage due to excessive current flow. The "Slo-Blo" feature indicates that the fuse can tolerate a temporary surge in current without opening, which is useful in circuits where inrush currents are common at startup.

The 045106.3MRL is a product manufactured by Littelfuse, Inc. Littelfuse is a company that specializes in circuit protection, power control, and sensing technologies.
