Additional Details

The PLP31DN900SL4L is a surface mount common mode choke that effectively suppresses common mode noise while minimizing the impact on the differential signal. It features a high common mode impedance, typically in the hundreds of ohms range, which effectively blocks common mode currents. The low differential mode impedance ensures that the differential signal is not significantly attenuated. Its compact size makes it suitable for use in space-constrained applications. It is designed for automated assembly using standard SMT equipment.

This common mode choke is commonly used in various applications, including USB, HDMI, LVDS, and Ethernet interfaces. In these applications, it helps to reduce EMI emissions and improve signal integrity. Proper grounding is crucial for effective common mode noise suppression. Ensure that the choke is properly grounded to the PCB ground plane. The component is designed to meet various regulatory standards for EMI emissions, such as FCC and CISPR. Consult the Murata datasheet for detailed specifications and application guidelines. This choke is an effective solution for mitigating common mode noise and ensuring compliance with EMI regulations.

Using a common mode choke like the PLP31DN900SL4L helps to prevent interference with other electronic devices and improves the overall performance of the system. Selecting the appropriate common mode choke depends on the frequency range of the noise, the impedance requirements of the signal lines, and the desired level of attenuation.
