CDN-M125E

Unscreened Power Supply Line CDN

The CDN-M125 is a single-line M-series Coupling Decoupling Network rated at 25 A, operating over a frequency range of 150 kHz to 230 MHz. It is recommended for power supply connections and is designed to inject common-mode RF disturbances onto EUT power lines in accordance with EN 61000-4-6. The M-series CDN ensures the required impedance over the ground plane while maintaining uninterrupted input power, and provides effective decoupling to minimize interference with the power source and auxiliary equipment.
