Product Details:
Overview
The Littelfuse 0452002.MRL is a highly reliable surface-mount fuse designed for robust circuit protection in compact electronic systems. Its primary function is to safeguard sensitive components from overcurrent events, with a critical operational characteristic being its slow-blow response time, which allows for temporary inrush currents without nuisance tripping. A key design consideration for engineers is balancing the need for a low DC cold resistance (0.0625 Ohms) to minimize voltage drop and power dissipation against the fuse’s physical size and breaking capacity, ensuring effective protection without compromising signal integrity or thermal performance.
Key Features
- Current Rating: 2 A
- Voltage Rating: 125 VAC/VDC
- Response Time: Slow Blow
- Breaking Capacity: 50 A @ 125 V
- Melting I²t: 8.2 A²s
- Dimensions: 6.10mm x 2.69mm x 2.69mm (0.240″ L x 0.106″ W x 0.106″ H)
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 sensitive analog front-end circuitry
- Inrush current management for motor control applications
- Secondary side protection in compact AC-DC converters
