“This new fuse our first with a high 1500 A interrupt rating at 277 V provides electronic designers using legacy through-hole solutions with an option to switch to an SMD part,” said Daniel Wang, Senior Director of Product Management, Over Current Passives, at Littelfuse. “By doing so, they can fully automate their assembly process, increasing production efficiency and reducing manufacturing costs.”
Key Features and Benefits:
• Industry-leading interrupting rating - With a 1500 A interrupting rating at 277 V, the Nano2 415 Series ensures protection against high fault currents in critical applications.
• Optimized for fluctuating voltage environments - The 277 V rated voltage provides true buffering in 250 V applications, safeguarding against unpredictable surges.
• Enhanced surge withstand capability - Higher I2t values compared to competitive solutions deliver improved surge and pulse withstand capacity.
• Compact, surface-mount design - The SMD form factor enables engineers to replace through-hole fuses, streamlining automated assembly processes and reducing overall production costs.
Ideal for High-Performance Applications
The Nano2 415 SMD Series is well-suited for a range of applications, including:
• Consumer electronics Power adapters, chargers, and power supplies;
• Industrial systems Inverters, converters, and instrumentation;
• Automotive EV charging stations, home chargers, and lighting;
• Appliances/White Goods Washers, dryers, and refrigerators;
• Home automation Automated garage doors and smart home systems.
A Competitive Advantage in Fuse Technology
The 415 Series provides a drop-in replacement option for other fuses on the market while delivering higher I²t values for superior surge withstand capability. Additionally, it serves as the SMD alternative to the Littelfuse 215 Cartridge Series, offering a higher voltage rating (277 V vs. 250 V) while replacing the existing through-hole cartridge fuse solutions. By transitioning to an SMD fuse, electronics engineers can fully automate their manufacturing processes, leading to faster production, higher throughput, and reduced labor costs ultimately making their end products more competitive in the market.
Availability
The 415 Series SMD Fuses are available in tape and reel format in quantities of 1,500. Sample requests are accepted through authorized Littelfuse distributors worldwide. For a listing of Littelfuse distributors, please visit Littelfuse.com.
