Configuration

Suggested PCB Layout

Note

1. It is recommended to use it separately, with a distance of 1mm from the side wall and 2mm from the upper cover, It supports 260 ℃ reflow soldering;

2: Grounding is very important, only good grounding can 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.
