MARKET INSIGHTS

Global Ammeter Shunt Resistors Market was valued at US$ 423 million in 2024 and is projected to reach US$ 658 million by 2032, at a CAGR of 5.7% during the forecast period 2025-2032. While China shows promising growth potential, the U.S. maintains significant market presence with ongoing technological advancements in electrical measurement systems.

Ammeter shunt resistors are precision components designed to measure high electrical currents by creating a low-resistance path parallel to the measurement circuit. These critical devices enable accurate current measurement through voltage drop calculation across a known resistance value. The market offers various types categorized by resistance tolerance: -0.5% to 0.5%, -1% to 1%, and -5% to 5%, with the highest precision segment expected to show notable growth.

The market expansion is driven by increasing electrification across industries, growing demand for energy-efficient systems, and stricter regulations for accurate power measurement. Key players like Murata, Vishay, and Panasonic dominate the competitive landscape, collectively holding significant market share through continuous product innovation and strategic partnerships in the electrical components sector.
