Overview

The Littelfuse 045202.5MRL is a critical component for safeguarding sensitive electronics, functioning as a 2.5A slow-blow surface-mount fuse designed for 125VAC/VDC circuits. Its primary role is to interrupt overcurrent conditions, preventing damage to downstream circuitry. A key design consideration for this fuse is its melting I²t value of 15.0, which dictates its energy handling capability; designers must balance the need for robust overcurrent protection against potential nuisance tripping in systems with significant inrush currents, a common trade-off in power supply design.

Key Features

  • Current Rating: 2.5 A
  • Voltage Rating: 125 VAC/VDC
  • Response Type: Slow Blow
  • Breaking Capacity: 50A @ 125V
  • Melting I²t: 15.0
  • 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.

  • Protection of power supplies in consumer electronics
  • Overcurrent mitigation in portable device charging circuits
  • Safety interlock in industrial control modules
  • Current limiting for LED driver boards
