NFp series suppress noise by conducting the high-frequency noise element to ground. Therefore, to obtain maximum
performance from these filters, the ground pattern should be made as large as possible during the PCB design stage. As
shown in the right, one side of the PCB is used for chip mounting, and the other is used for grounding.
Small diameter feedthrough holes are then used to connect the grounds on each side of the PCB. This reduces the high-
frequency impedance of the grounding and maximizes the filter's performance.

• Do not apply narrower pattern than listed above to BLMppP.
o Flow Soldering (Except NFE61HT332)
Do not use gild pattern; excess soldering heat may dissolve

Narrow pattern can cause excessive heat or open circuit.
The chip EMI filter suppress 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.
• NFM21 is specially adapted for reflow soldering.
