Bar Shape Shunt Resistor
Products Description
A Bar Shape Shunt Resistor is a low-resistance, high-stability current sensing element. By precisely controlling the resistance value of the shunt resistor, a measurable voltage signal is generated when current flows through it, thereby achieving current monitoring and protection control.
Compared to traditional monolithic shunt resistors, this product adopts a composite metal structure design:
Core material: Manganin
It has an extremely low temperature coefficient (TCR) and excellent resistance stability.
End materials: High-conductivity copper
Provides excellent conductivity and mechanical strength while reducing overall power consumption.
Manganin and copper strips are metallurgically bonded using electron beam laser welding technology, and then precision stamped into a strip structure, giving the product high precision, low thermal drift, and excellent mechanical stability.
This composite structure not only ensures measurement accuracy but also makes the product more suitable for automated assembly and mass production environments.
Design Advantages: Adaptable to Complex Spaces and Electrical Requirements
Bar Shape Structure
The compact Electric Current Measure Manganin Shunt design significantly saves valuable internal space within the relay, facilitating miniaturization.
Customizable Shapes

Detailed Showcase: Quality You Can See
Microscopic Details of the Weld
Under a metallographic microscope, the bonding surface of the copper and manganese copper exhibits a perfect wavy fusion line, with no obvious porosity or cracks. The grains of the two metals are interpenetrated, demonstrating the high quality of "metallurgical bonding."
Details of the Stamped Section
The edges of the strip distributor are straight, with a high proportion of bright bands on the cross-section, and no tear marks. This reflects the high precision of our molds and the stability of our stamping process.
Identification and Traceability
Each batch of Brass Terminal Lead Shunt Resistor packaging includes a unique traceability code, recording the raw material batch, welding parameters, stamping batch, and quality inspection report, meeting the traceability requirements of automotive and power supply chains.
