Current shunt resistor solution for high-performance current sensing

Littelfuse, Inc. has launched its SSA Series Current Shunt Resistors – the first in its portfolio. These two-terminal, ultra-low stance shunt resistors are uniquely designed to satisfy the increasing demand for accurate current measurement in high-performance applications.

Unlike competing technologies such as Hall effect sensors, current transformers, flux gate sensors, and Rogowski coils, this current shunt resistor provides a more efficient solution that works well in AC and DC circuits. With a higher power rating than metal foil resistors, the series excels in applications demanding rigorous current sensing due to high-power requirements.

This versatility makes it an excellent option for various markets and applications, including automotive electronics, EV charging, large appliances, data centres, industrial, power modules, and frequency converters.

"Accurate current measurement is crucial for the optimal performance of electrical and electronic devices," says Stephen Li, Product Manager at Littelfuse. "With the ever-increasing demand for high-performance devices, our SSA Series Current Shunt Resistors offer a cost-effective solution for both AC and DC applications requiring demanding current sensing."

"The SSA Series Current Shunt Resistors provide an affordable solution for accurate current measurement and control," adds Li. "We are confident that our customers will greatly benefit from the exceptional performance and reliability of this new addition to our current sensing resistor product range."
