The CDND M316-16B is a coupling/decoupling network specifically developed for testing the immunity of devices to broadband conducted disturbances as defined by IEC/EN 61000-4-31, covering the frequency range of 150 kHz to 80 MHz. This device offers a longitudinal conversion loss (LCL) of 16 dB, allowing the injection of both common-mode and differential-mode signals into the EUT port. Designed for versatile use, it supports both configurations with and without protective earth connections. The CDND M316-16B ensures accurate and reliable testing of electromagnetic immunity, helping manufacturers meet the stringent requirements of the EMC standard.
