456SD Series - NANO2® High Current Subminiature Surface Mount Fuse

Roll Over to Zoom

The 456SD Series NANO²® fuse is a small sized, surface-mountable high current fuse which provides over-current and excessive surge current protection for applications operating at high current in a limited space. This will be a supplementary offering to the existing 456 and 881 Series where the 50A fuse rating is not available.

Such applications are mostly served today through a single large-sized high-current industrial type fuse or in some cases, parallel configuration of lower amperage SMD fuses. The 456SD 50A Series fuse gives the option of a single fuse solution for protection for such application requirements.

Features:

  • Available in ratings of 40 to 50A
  • High interrupting rating - 600A@75VDC
  • Very low cold resistance, temperature rise, and voltage drop
  • High inrush/surge current withstand capability
  • Surface mountable high current fuse

 Benefits:

  • Single fuse solution for high current application
  • Suitable for a wide variety of voltage requirement and application
  • Enhances power efficiency
  • Avoids nuisance opening due to high inrush and surge current inherent in the system
  • Compatible with high volume assembly requirements

Applications:

  • Voltage regulator module for PC server
  • Cooling fan system for PC server
  • Storage system power
  • Basestation power supply
  • Power tools
