It's the manufacturer's mark (Littelfuse).

    \$\begingroup\$ Littelfuse has a somewhat confusing marking system for their cartridge fuses as the datasheet (littelfuse.com/…) gives the ordering part number but the cap number is found on a different sheet (littelfuse.com/~/media/files/littelfuse/technical-resources/…). I believe the P at the end stands for lead-free (Pb-free). \$\endgroup\$
