Configuration

Suggested PCB Layout

Note

1: Suggest using separate chambers with interchangeable ports, with a distance of 1.0mm from the side wall on one side and a distance of 2.0mm from the top cover on the surface. Supports reflow soldering at 260 ℃;

2: Good grounding is necessary to maximize the performance of the filter.

3: During the cleaning process, the filter should not be immersed in the cleaning solution for a long time;

4: Filling absorbing material above the filter can achieve better harmonic suppression.
