New Littelfuse Surface Mountable 600VDC Fuse Announced Providing Exceptional Overcurrent Protection

It offers circuit designers a compact, cost-competitive alternative to traditionally larger, through-hole-type fuses for creating cost-effective designs in accordance with the industry trend for surface mount designs. Its fast-acting blow characteristics ensure high-speed protection against surge currents and overload conditions. Applications include use in high-end PC servers, telecom power distribution systems, LCD/PDP TV inverter boards DC input protection, uninterruptible power supply (UPS) systems, 3-phase power supplies, 380VDC servers/lighting in data centers.

“The 485 Fuse Series complements and further broadens the Littelfuse line of surface mount fuses used for the secondary side of circuit protection,” said Daniel Wang, director of global product management for the 485 Series Fuse. “It deepens our offering of quality overcurrent protection solutions for industrial and data center applications.”

The 485 Series Fuse offers circuit designers a variety of key features and benefits:

Features
• High voltage/interrupting rating in small SMT footprint (12.1 x 4.5 x 4.5 mm)
• High operating temperature range from -55°C to 125°C
• 100% RoHS compliant and halogen free
• Available with current ratings from 500mA to 3.15A, certified UL approved

Benefits
• Lowers total cost of power supply design with SMT installation
• Supports high voltage DC power architectures for state-of-the-art, high efficiency data centers
• High interrupt capability allows protection of high wattage power supply architectures driving next generation efficient data centers
• High reliability design and high operating temperature range support demanding mission critical power systems

Availability
The 485 Series Fuse is available in quantities of 1,500 in standard tape and reel packaging. Samples are available now for bulk orders; sample requests can be placed through authorized Littelfuse distributors worldwide.
