SMD Metal Shunt Jumper Bar with Molded Insulation | High Current PCB Link

Description

Overview

SMD Metal Shunt Jumper Bar with Molded Insulation for High Current PCB Applications

The SMD 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 metal jumper bar is manufactured from a solid alloy element with a tin-plated surface for excellent solderability and long-term connection reliability. The molded plastic insulation layer provides reliable 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 shunt jumper bar is ideal for PCB power distribution, EMS boards, battery systems, and other high-current electronic applications where space-saving and reliable current paths are required.
