High Current Ring Core Chokes

TDK Electrical and electronic equipment generates common-mode interference. In order to meet the safety requirements within the leakage current limits, chokes with a high asymmetrically effective inductance must be used. TDK common-mode chokes with a closed core topology are especially suitable for this purpose.
