High-performance common-mode chokes for automotive Ethernet applications

Now stocked by TTI Europe, the TDK ACT45L series of common-mode chokes for automotive Ethernet applications features the industry's best common-mode noise suppression. The higher the attenuation of the noise is, the better the performance of the common-mode choke, says the company. The noise suppression of the ACT45L is between 15dB and 25dB - better than existing products over a broad frequency range up to 100MHz. The AEC-Q200 qualified ACT45L series offers a rated inductance of 200µH and can operate in a broad temperature range from -40C to +105C. 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 needs, says the company.
