QHow is this different from a zero-ohm jumper?
A power jumper provides a substantially larger conductive cross-section and controlled standoff space.
3D PCB Crossovers
SMT Power Jumpers
SMT POWER JUMPERS
Board-level high-current crossovers for routing clearance and automated reflow assembly, assessed by span, standoff height, pad width, material and electrical duty.
This page describes a product family and selection inputs. Confirm current rating, temperature rise, tolerances, certification scope and lead time against the selected part, drawing and valid records. Illustrations are not product or factory evidence. Cu-Al figures come from supplied material documents and apply only to their samples and conditions, not a blanket certification or system cost guarantee.

Engineering & Selection FAQ
QCan it replace hand-soldered wire?
Replacement is assessed after current, temperature, strength, pad and reflow validation.
