Common mode chokes ideal for automotive EPS noise suppression applications

TT Electronics has launched the HA19 series of common mode chokes for use in electronic power steering (EPS) noise suppression applications. With high performance and AECQ-200 certification, the series devices are ‘automotive-ready’ for the new generation of motor vehicles. Every EPS system requires proper EMI control with a CMC and/or a DMC serving this function. With the increasing shift to EVs and PHEVs, and the expedited inclusion of electronic components in automobiles, noise suppression has become more important to ensure EMI compliance. The series common mode chokes are designed with the company’s extensive expertise and excellence in noise suppression performance in chokes that the company has supplied for EPS applications over the last 15 years. The series embraces the company’s holistic approach to specialised component design to create products that are feature-rich, highly efficient, safe and reliable. The result is design and manufacturing solutions for magnetics that have a systematic adherence to the safety standards and quality required by the automotive industry. The series is a proven solution to eliminate noise emission induced by high radiated frequencies and low conducted frequencies in system circuitry, enabling EPS system designers to improve EMI robustness, ensuring safe vehicle operation.
