Procurement Notes
Verify the complete part number including suffixes against official Murata documentation to ensure correct capacitance and packaging specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Cross-reference manufacturer datasheets for accurate lead times and availability as distributor listings may vary.
Selection Notes
Select this component when designing circuits requiring significant current handling alongside effective EMI attenuation. The 6A rating distinguishes it from lower-current signal filters. Ensure the 1206 footprint aligns with the target PCB layout constraints and that the operating voltage does not exceed the 25V DC limit.
Part Context
This component belongs to the Murata EMIFIL® NFE31 series, which focuses on low-pass filtering solutions. The NFE31PT variant specifically addresses high-current applications using an LC topology. It serves as a specialized passive component for electromagnetic interference mitigation in modern electronic systems.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with alternative components based on identical electrical parameters and physical dimensions before substitution.
