Keystone Electronics Corp. Vertical Entry 2 Position Standard Auto Blade Fuse Holder 3522-3

The 3522-3 is a vertical-entry, two-position through-hole mount fuse holder designed for standard automotive blade fuses, such as those in the Littelfuse ATOF 287 or Bussmann ATC series.

The holder supports a UL current rating of 20 amps at 500V AC and operates within a temperature range of -50°C to +145°C. Its mounting dimensions include four 2.6mm diameter holes for secure PCB attachment, and the design prevents solder wicking during wave soldering.
