- Common mode interference reduction in electronic devices
Procurement Notes
Verify the specific datasheet version to confirm exact electrical tolerances and package dimensions. Ensure the application environment does not exceed the rated DC current or withstand voltage limits. Cross-reference the manufacturer's part number with official distributor catalogs to avoid counterfeit components. Confirm RoHS compliance status if required for your assembly process.
Selection Notes
Select this component when a compact surface mount solution is needed for dual-line noise attenuation. Consider the 470 µH inductance value relative to the target noise frequency spectrum. Evaluate the 700 mA current rating against the circuit's operational load to prevent saturation. The small footprint allows for integration into space-constrained PCB layouts.
Part Context
This component belongs to the 5000 series of surface mount common mode chokes from Murata Power Solutions. These chokes are designed for high-frequency noise suppression in various electronic systems. The series offers standardized footprints and electrical characteristics to simplify design-in processes for engineers requiring reliable EMI filtering solutions.
Replacement Considerations
Consult official Murata documentation for direct substitutes within the 5000 series. Verify that any alternative part matches the 470 µH inductance and 700 mA current rating. Ensure the replacement maintains the same surface mount package dimensions for compatibility.
