C&B EUREKA INNOVATIONS CO., LIMITED：25 μΩ / ±0.1% / ±15 ppm/°C High-Precision Shunt Module Launched — ±0.3% Accuracy Across the Full Temperature Range Without Temperature Compensation

SHENZHEN, China, Sept. 03, 2026 (GLOBE NEWSWIRE) -- C&B EUREKA INNOVATIONS CO., LIMITED / C&B RESI - In new energy vehicles, DC charging equipment, and electric construction machinery, current sensing is critical to energy management, power control, and system protection. As current levels increase, measurement errors caused by shunt self-heating, temperature variations, and thermal EMF at connection points become more significant. The C&B RESI HRES8436BL025MST0 shunt-based current sensing module is engineered specifically for high-precision current measurement at kiloampere levels.

The HRES8436BL025MST0 offers the following features to improve the reliability and stability of high-precision current sensing:

1. Initial resistance tolerance of ±0.1% for improved current measurement accuracy.
2. Maximum TCR of ±15 ppm/°C from +20°C to +125°C, minimizing the temperature coefficient on measurement accuracy.
3. Maximum thermal EMF coefficient of 0.6 μV/°C from −40°C to +125°C, effectively reducing measurement errors associated with installation.
4. A proprietary shunt structure that ensures stable, high-precision current sensing regardless of mounting orientation.
   
   

With its low TCR, high accuracy, low thermal EMF, and innovative structural design, the HRES8436BL025MST0 maintains a maximum resistance variation of ±0.3% across a wide temperature range from −40°C to +125°C. No software-based temperature compensation is required to achieve ultra-high-precision current sensing. This makes it ideal for new energy vehicles, DC charging stations, construction machinery, eVTOL aircraft, industrial power supplies, and other high-current applications requiring demanding measurement accuracy.

In a new energy vehicle battery management system (BMS), for example, the ±0.1% initial resistance tolerance and ±15 ppm/°C TCR enable high-precision, high-current measurement with ±0.3% accuracy—without software compensation. The combination of ±0.1% initial tolerance and a thermal EMF coefficient of just 0.6 μV/°C significantly improves measurement accuracy in low-current operating conditions, such as sentinel mode

Its unique structural design also maintains measurement accuracy in space-constrained installations and less-than-ideal mounting conditions. In addition, C&B RESI’s vertically integrated and independently controlled supply chain ensures outstanding product consistency and a stable supply, making the HRES8436BL025MST0 particularly well suited for high-precision current sensing in automotive BMS applications.

C&B RESI, the manufacturer of the HRES8436BL025MST0, has long specialized in the research, development, and manufacturing of high-performance resistors, current-sensing components, and modules. The company has established strong partnerships with many internationally renowned enterprises.
