Configuration

Suggested PCB Layout

Note

1:建议分腔使用,端口可互换,单侧距离侧壁1.0mm,表面距上盖2.0mm,支持260℃回流焊;

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.
