Product Attributes

Introduction

The 494 Series Fast-Acting SMF is an ultra small (0603 size) thin-flm device designed for secondary protection of circuits used in space constrained applications such as hand-held portable electronic devices. This series is 100% lead-free and meets the requirements of the RoHS directive. New Halide-Free 494 Series fuses are available to order using the “HF” suffx.

Features

• Compatible with leadfree solders and higher temperature profles
• High performance materials provide improved performance in elevated ambient temperature applications
• Marked on top surface with code to allow amper rating identifcation without testing
• Low profle for height sensitive applications
• Flat top surface for pickand-place operations
• Element-covering material is resistant to industry standard cleaning operations
• Mounting pad and electrical performance are identical to Littelfuse 431 and 434 Series products
• Alloy-based element construction provides superior inrush withstand characteristics (I2t) over ceramic or glass-based 0603 fuse products

Applications

• Secondary protection for space constrained applications:
• Cell phones
• Digital cameras
• Hard disk
• Battery packs
• DVD players drives
