Procurement Notes
Verify the manufacturer part number against official Laird documentation to ensure authenticity. Confirm that the specific suffix matches the required impedance and current ratings. Check RoHS compliance status as indicated in the latest datasheet. Ensure storage conditions align with the specified operating temperature range to maintain performance integrity.
Selection Notes
Select this component when a 300 Ohm impedance at the target frequency is required for common mode noise reduction. Ensure the circuit's DC current does not exceed 3.7 A to prevent saturation or excessive heating. Verify that the 5x5 mm package fits the available PCB real estate and that the soldering process accommodates the SMD termination type.
Part Context
This component belongs to the Laird-Signal Integrity Products portfolio of passive filters. It is designed to mitigate electromagnetic interference in electronic systems. The product falls under the category of common mode chokes, distinct from ferrite beads or standard inductors, focusing on differential mode signal preservation while attenuating common mode noise.
Replacement Considerations
Consult official Laird catalogs for direct substitutes with identical electrical parameters. Verify pin compatibility and thermal characteristics before substitution. Generic equivalents may lack the specific current handling or impedance profile required for critical signal integrity applications.
