Product Attributes

Introduction

The 494 Series fast-acting surface mount fuses are ultra-compact thin-film devices designed for secondary circuit protection in space-constrained applications. The entire series is fully lead-free and RoHS compliant. A new halogen-free version of the 494 Series fuse with the "HF" suffix is available for ordering.

Features

• Compatible with lead-free solder and higher-temperature soldering processes
• High-performance materials deliver superior performance in elevated ambient temperature applications
• Current rating identified by marking code on top surface — no testing required
• Low-profile design for height-sensitive applications
• Flat top surface for pick-and-place operations
• Component coating material withstands industry-standard cleaning processes
• Mounting pads and electrical characteristics identical to Littelfuse 431 and 434 series
• Alloy-based construction provides superior surge resistance compared to ceramic or glass-body 0603 fuse products

Applications

• Mobile phones
• Digital cameras
• Hard disk drives
• Battery packs
• DVD players
