Description
Overview
Metal Shunt Jumper Bar for High-Current PCB Applications
The Metal Shunt Jumper Bar is a low-resistance PCB-mounted conductor designed for high-current routing, circuit bypass, and reliable electrical connections in power electronic systems.
Unlike conventional zero-ohm chip resistors, this SMD metal jumper is manufactured from a solid alloy element with a tin-plated surface, providing excellent solderability and reliable electrical connection. The molded plastic insulation layer provides electrical isolation and mechanical protection while maintaining a compact, SMT-friendly design.
With its low resistance, high current capability, and stable thermal performance, this SMD jumper bar is suitable for PCB power distribution, EMS/PCBA assemblies, battery systems, inverter boards, and other high-current electronic applications where a compact and reliable current path is required. For applications using conventional chip-style connections, it can also serve as an alternative to an SMD zero ohm jumper where higher current capability is required.

FAQ – SMD Metal Jumper Bar
What is an SMD metal jumper bar?
An SMD metal jumper bar is a low-resistance PCB-mounted conductor designed to provide a compact, reliable electrical connection for high-current PCB routing, circuit bypass, and power distribution.
How is an SMD metal jumper different from a zero-ohm resistor?
An SMD metal jumper is primarily designed as a high-current electrical connection rather than a conventional resistance component. Its solid metal construction can provide higher current capability, lower resistance, and improved thermal performance for suitable PCB applications.
What current ratings are available?
Standard options range from 10A to 40A. Higher-current configurations may be available depending on the jumper dimensions, material, PCB layout, and thermal conditions.
What insulation method is used?
A molded plastic insulation layer provides electrical isolation and mechanical protection while allowing the component to be used in compact SMT assemblies.
Can the SMD jumper bar be customized?
Yes. Customized dimensions, PCB footprints, current ratings, insulation structures, materials, and surface finishes can be developed according to application requirements.
