Reflow Soldering
NFM18C/NFM18PC/
NFL18ST
The chip EMI filter suppresses noise by conducting the high-
frequency noise to ground. Therefore, to get enough noise reduction,
feed through holes which are connected to ground-plane should be
arranged according to the figure to reinforce the ground pattern.
• NFp18, NFp21, NFM55 are specially adapted for reflow soldering.
