RT8122-20-3M0 Details

Schaffner recommends a symmetrical PCB layout with a solid ground plane, and the use of vias to connect the filter's ground pins to the ground plane. Additionally, the input and output traces should be kept short and away from each other to minimize electromagnetic interference.
The RT8122-20-3M0 is rated for operation up to 80°C, but derating may be necessary for higher temperatures. Schaffner recommends consulting their application notes for temperature derating guidelines.
The RT8122-20-3M0 meets various safety certifications, including UL, ENEC, and CQC. However, the final product must also meet the relevant safety standards. Engineers should ensure that their design meets the necessary safety requirements and consult with Schaffner's technical support if necessary.
Schaffner recommends using the provided screws to secure the filter to the PCB, and ensuring that the filter is mounted in a way that minimizes mechanical stress and vibration.
Yes, the RT8122-20-3M0 can be used in a redundant or parallel configuration, but engineers should ensure that the filters are properly synchronized and that the system is designed to handle the increased current and power dissipation.
