SinglFuse™ Part Numbering System (cont’d)

The next 3 or 4 digits indicate the rated current. In this example, 100 represents 1 A. If the part number showed 1000, that would indicate a 10 A rated current. After that, a letter character represents the fuse structure. In this case, W represents Bourns’ Wire Core fuse structure. Finally, the last character represents the packaging type, with a 2 indicating tape and reel.
