Littelfuse Introduces Single Fuse Solution for Applications requiring high current ratings and compact construction
Littelfuse, Inc., a global leader in circuit protection, recently unveiled its UL-certified high-current surface mount fuses at the 2017 PCIM exhibition in Europe (Hall 7, Booth 335). These new fuses are designed for applications that demand compact designs and robust overcurrent protection. The Nano2 881 series offers a single-fuse solution with voltage ratings up to 75VDC and current ratings ranging from 60A to 100A. This eliminates the need for multiple low-rated fuses or bulky industrial fuses, making it ideal for space-constrained designs.
The 881 Series features a small footprint (12.5mm x 10mm) and a low profile (6.8mm), making it perfect for high-current applications. It also delivers exceptional performance with minimal voltage drop and low temperature rise, improving power efficiency and reducing energy loss. The fuses can operate reliably in a wide temperature range (-55°C to 100°C), ensuring durability in various environments.
Common applications include data center equipment such as blade servers, server chassis, backplanes, and line cards. In the power systems market, they are used in uninterruptible power supplies (UPS), base station power supplies, high-power battery systems, and power factor correction circuits.
Daniel Wang, Global Product Management Director at Littelfuse Electronics Business Unit, said: “The 881 Series provides a single fuse alternative for high-current applications where board space is limited. Designers can replace two parallel low-rated fuses with a single 881 Series fuse, saving valuable space.â€
Key advantages of the 881 Series include:
- Current ratings from 60A to 100A with a compact design.
- Eliminates the need for multiple low-rated fuses or large industrial fuses.
- High interrupt current capability (up to 1500A at 75VDC).
- Fast disconnection time (up to 60 seconds at 200% overload), compared to industry standards (typically 120 seconds).
The Nano2 881 series is available in a 24mm surface mount tape and reel package, with a minimum order quantity of 500 units. Free samples are available through authorized Littelfuse dealers worldwide. For more details, visit Littelfuse.com or check the product page for the Nano2 881 series.
