The ACT45L series of common-mode chokes for automotive Ethernet features today’s best common-mode noise suppression. The higher the attenuation of the noise is, the better the performance of the common-mode choke.
Thanks to TDK’s advanced technologies, the noise suppression of the ACT45L is between 15dB and 25dB better than existing products over a broad frequency range up to 100MHz. The ACT45L series offers a rated inductance of 200µH and can operate in a broad temperature range from −40°C to +105°C. Measuring in with a footprint of 4.5mm × 3.2mm and an insertion height of just 2.8mm, the miniaturized ACT45L series is the smallest common-mode choke now available for automotive Ethernet. The ACT45L series is designed for fully automated manufacturing processes. After two windings and the terminal electrodes are applied to the rectangular DR core, an SP core is bonded to it with a temperature- and moisture-resistant adhesive. The result is a new series of automotive components with high reliability and consistent quality that are qualified to AEC-Q200.
