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 below, 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.
• Please read rating and !CAUTION (for storage, operating, rating, soldering, mounting and handling) in this catalog to prevent smoking and/or burning, etc.
• This catalog has only typical specifications because there is no space for detailed specifications. Therefore, please review our product specifications or consult the approval sheet for product specifications before ordering.
