The JCASE™ is a cartridge style fuse with female terminal design, providing both increased time delay and low voltage drop to protect high current circuits and handle inrush currents. The JCASE™ was designed and patented by Littelfuse.

JCASE™ fuses have similar failure characteristics to fusible links, which is why you’ll find them under the hood of modern vehicles.  In addition, they’re far easier to replace.
