WJC-A Surface-Mount High Current Jumpers

Littelfuse WJC-A Surface-Mount High Current Jumpers are AEC-Q200 qualified and offer 1mΩ maximum resistance and 40A maximum current. These metal foil jumper chip modules with Kelvin sensing feature a glass epoxy substrate in a variety of package sizes, including 0201, 0402, 0603, 0805, and 1206. The WJC-A series is designed to offer excellent performance in resistance, noise performance, and surface heat distribution, and the modules have a lower surface temperature. Littelfuse WJC-A Surface-Mount High Current Jumpers are halogen free, lead free, and RoHS compliant. Applications for WJC-A current sense resistors include power management, servers, automotive, and those with low equivalent series inductance (ESL).
