Global Metal Alloy Current Sense Resistors for AI Servers Market Strategic Research Report

Scope of the Report

The global Metal Alloy Current Sense Resistors for AI Servers market size is predicted to grow from US$ 77.36 million in 2025 to US$ 372 million in 2032; it is expected to grow at a CAGR of 24.0% from 2026 to 2032.

Alloy sampling resistors for AI servers are low-resistance, precision current-sensing resistors used in GPU/AI accelerator cards, CPU motherboards, power supplies, 48V/54V power architectures, DC-DC converters, hot-swappable power supplies, BBUs, and rack-mounted power systems. These products typically utilize metal alloy resistors, such as manganese-copper or nickel-copper, to measure current, monitor power, provide overcurrent protection, and manage loads by detecting the minute voltage drop across the resistor. Typical products feature low resistance values ranging from 0.1 to 100 mΩ, low TCR, high power density, high pulse capability, and 2-terminal or 4-terminal Kelvin configurations.

In 2025, global sales of alloy sampling resistors for AI servers reached 447.5 million units, with an average price of $168 per thousand units.

AI Servers Drive New High-Value Demand

Increased GPU power consumption has led to a rise in the number of VRMs, power modules, 48V architectures, power conversion components, and board-level current monitoring devices. Compared to standard PCs, AI servers not only require a greater number of sampling resistors but also tend to use products with low TCR, high power handling, and compact designs. Consequently, their contribution to the market is reflected more in value growth than in sheer unit volume growth.
