SMD Zero Ohm Jumper for High Current PCB Applications | Copper Jumper Bar

Description

Overview

SMD zero ohm jumper are compact metal interconnection components designed for high-current PCB applications, replacing traditional wire links in modern electronic assemblies.

Unlike conventional chip zero ohm resistors, these metal jumper solutions are optimized for higher current carrying capability, lower electrical resistance, and improved mechanical reliability.

Manufactured from high-conductivity copper with a tin-plated surface, the jumper provides excellent solderability, strong overload capability, and stable performance for industrial power electronics, motor control systems, battery monitoring equipment, and compact power modules.

The low-inductance straight structure helps minimize parasitic effects, making it suitable for applications requiring efficient current distribution and reliable PCB power connections.
