Description
SMD Metal Jumper Bar for High-Current PCB Applications
The SMD Metal Jumper Bar is a high-current surface-mount PCB jumper designed to provide a reliable, low-resistance electrical connection between PCB nodes. It is suitable for applications where a conventional 0Ω chip resistor or wire jumper cannot provide sufficient current-carrying capability.
Constructed from a metal alloy plate with a tin-plated surface and protected by a molded insulation layer, this high-current SMD jumper combines reliable SMT soldering, mechanical protection, and electrical isolation in a compact PCB-mounted package.
With rated current capabilities from 10A to 40A, the SMD Metal Jumper Bar provides a compact alternative for high-current PCB connections, circuit bypassing, and power routing. Its non-inductive structure and low resistance make it suitable for power electronics, battery systems, inverter boards, industrial controls, and other high-current electronic assemblies.

SMD Metal Jumper vs. Conventional 0Ω Resistor
A conventional 0Ω chip resistor is commonly used as a PCB link or configuration component, but its current-carrying capability is limited by its package size and construction.
The SMD Metal Jumper Bar uses a metal plate structure to provide a larger conductive cross-section and higher current capability while maintaining a compact surface-mount form factor.
It can be considered when a PCB design requires:
- Higher current capability than a conventional 0Ω chip resistor
- A compact SMT connection instead of a wire jumper
- Low electrical resistance
- Reliable soldered PCB connection
- Electrical insulation around the conductive element
- A non-inductive or low-parasitic-inductance connection
