Product Details:
Overview
The Littelfuse 0452002-MRL is a 2A, 125VAC/VDC surface-mount fuse designed for robust circuit protection in compact electronic assemblies. Its primary function is to safeguard sensitive components from overcurrent conditions, offering a slow-blow response characteristic crucial for circuits with inrush currents, such as motor drivers or power supplies. A key design consideration for this NANO²® 452 series fuse is balancing its high breaking capacity (50A @ 125V) with its small 2-SMD footprint; designers must ensure adequate thermal management around the device to prevent premature nuisance tripping under sustained moderate loads, a common trade-off in miniaturized protection solutions.
Key Features
- Current Rating: 2 A
- Voltage Rating: 125 VAC/VDC
- Response Time: Slow Blow
- Breaking Capacity: 50 A @ 125 V
- Dimensions: 6.10mm x 2.69mm x 2.69mm (0.240″ L x 0.106″ W x 0.106″ H)
- Operating Temperature: -55°C to 125°C
Applications
The component is engineered for deployment in systems requiring high reliability and performance under specific operating conditions. It provides functional stability across the stated design envelope.
- Power supply input stage overcurrent protection
- Protection of downstream DC-DC converters in battery-powered devices
- Inrush current management for small motor control circuits
- Secondary side protection in compact AC-DC adapter designs
