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: 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.
