Littelfuse, Inc. 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
Electrical equipment

"These new fuse blocks provide our customers with greater flexibility and choice," said Style Liu, Global Product Manager at Littelfuse. "By offering higher amperage ratings, we ensure our customers have the necessary options to meet their specific application requirements."

The 656 and 658 Series Fuse Blocks offer the following key benefits:

Provides PCB-mounted and surface-mounted solutions for designs that require 5 x 20mm fuse sizes
High voltage 500 V AC/V dc rating with 30 A current rating that accommodates many power applications
