Russell announced the launch of a 500VDC SMD fuse optimized for electric vehicle applications

Russell sponsors a series of battery management system seminars covering all aspects of the BMS engineering design process. One of the partners who participated in the seminar, Littelfuse, has now introduced the NANO2® 885 series of surface mount fuses with rated interrupt currents up to 1500A, and Optimized for high voltage automotive applications up to 350VAC or 450 / 500VDC.

The NANO2® 885 series fuses are designed to protect electric vehicles from severe faults and short-circuit currents, ensuring reliability in harsh environments. The 885 Series fuses are small in size and occupy an area of ​​only 10.86mm x 4.78mm, which is 450/ face on the market. The smallest surface mount fuse for 500VDC automotive applications, ideal for board space limitations and unsuitable for conventional through-hole fuses. The 885 Series fuses are rated for 1A to 5A.

Typical automotive use cases for the 885 Series fuses include:

锂Lithium-ion battery pack for electric vehiclesBattery management system (BMS) Induction line Car charger High-voltage DC/DC converter

Uwe Rahn, Director of Automotive Business Unit of Rudolf, said: 'Safety is a key factor in the design of electric vehicles. Fuses for electric vehicle applications must be designed for high voltage and high current with high reliability. They must Compact in size for space-constrained vehicle environments, it is extremely rugged, able to withstand vibration and corrosive chemicals, and meets standards. Littelfuse's 885 Series meets all of these requirements, and we are pleased to incorporate this range of devices into Condoli In the product portfolio. '

The main advantages of the Littelfuse 885 series

The 885 Series fuses have the following main advantages:

电动Reliable protection for electric vehicles with DC rated voltages up to 500VDC and rated interrupt currents up to 1500A to prevent damage from severe faults and short-circuit currents. 885 series fuses are ruggedly designed, using a solderless platform to maximize Reduces the risk of false openings due to mechanical welding errors and provides better performance for stable operation.  Compliance with Littelfuse's automotive-grade qualification based on the AEC-Q200 test program to ensure superior reliability in harsh automotive environments .

Daniel Wang, Director of Global Product Management, Littelfuse Electronics Business Unit, said: 'The Series 885 fuse solves the space constraints common in automotive applications. Its solderless platform minimizes the risk of failure due to mechanical welding errors in typical conventional fuses. To ensure stable overload performance. '

Supply

The minimum purchase quantity of NANO2®882 series fuses is 1,500 tapes. Samples can be obtained from Littelfuse authorized distributor Rudolf.
