Littelfuse Launches High Amperage Rating Fuse Blocks for 5x20mm Fuses

Available in surface- and through-hole mount options to support more demanding applications

CHICAGO, September 5, 2023 —  Littelfuse, Inc. (NASDAQ: LFUS), an industrial technology manufacturing company empowering a sustainable, connected, and safer world, announced the latest release of the 656 and 658 Series Fuse Blocks product line. These fuse blocks offer a higher amperage rating, giving electronics engineers and designers more options depending on their specific application requirements.

The key differentiator of these high-resistance fuse blocks is their ability to support a higher amperage rating available in PCB-mounted (656) and surface-mounted (658) options. While the current versions are rated up to 16 A, Littelfuse is now offering versions rated at 20 A and 30 A. This expanded range allows customers to choose the appropriate amperage rating based on the needs of their applications, which include:

  • Consumer electronics,
  • Data centers,
  • Telecom,
  • Building and home automation,
  • Appliances,
  • HVACR,
  • General industrial, and
  • Electrical equipment.

These new fuse blocks provide our customers with greater flexibility and choice.
