Product Introduction
SMT Manganin Alloy Resistor is a surface‑mount current‑sampling resistor constructed with high‑quality manganin alloy. Available in 2512, 3920, 5930 chip packages. Based on manganin material’s excellent low‑temperature‑drift property, this chip resistor generates precise voltage drop when current passes through, to realize accurate DC current detection. It replaces traditional through‑hole shunts for automated SMT assembly, saving PCB space for power equipment.
