Littelfuse introduced a series of UL approved high-current, surface mount fuses designed for applications that require both a compact footprint and protection from ultra-high currents.
The Nano2 881 series high-current SMD fuses offer a single fuse solution up to 75 V d.c. and are available in current ratings from 60 A to 100 A. These high current ratings eliminate the need to parallel multiple lower-rated fuses and to use larger, over-spec industrial type fuses – common ways circuit designers typically address applications that require fuses with high current ratings. The series includes the first 100 A SMD fuse available on the market.
The 881 series has minimal voltage drop and low temperature rise, which enhances power efficiency by optimising thermal performance and minimising power loss. With an operating range from -55°C to 100°C, the fuses are suitable for use in existing operating environments. Their robust design enhances reliability and reduces susceptibility to temperature cycling and vibration effects.
Typical applications for the 881 series in the data centre market include blade servers, server chassis, backplane boards and line cards. Additional applications in the power system market include uninterruptible power supplies (UPS), base station power supplies, high-power battery systems and power factor correction (PFC) in high-wattage power supplies.
Measuring 12,5 x 10 mm, the fuses have a high interrupting rating of 1500 A @ 75 V d.c., and feature a fast opening time of 60 seconds at 200% load current to ensure protection against overload and short circuit events.
