Procurement Notes
Verify the part number suffix against official documentation to confirm specific shielding or material variations. Ensure compatibility with automotive grade requirements before procurement. Confirm packaging quantities and handling specifications directly with the manufacturer or authorized distributors to maintain component integrity during storage and installation.
Selection Notes
Select this component based on its 2.8A current rating and 1400 Ohm impedance characteristics. Consider the shielded construction for environments requiring reduced radiated emissions. Verify that the surface mount footprint matches the target PCB layout constraints and thermal management requirements for the intended application.
Part Context
This component belongs to the WCM5555FASV series of wire wound power common mode filters produced by TAI-TECH. The series includes various impedance variants tailored for different noise suppression needs. The 'LM' designation typically indicates specific material or process attributes within the product family.
Replacement Considerations
Compatible alternatives include the WCM5555FASV-501-LM and WCM5555FASV-701-LM from the same manufacturer. These parts share similar form factors but differ in impedance and current ratings. Verify electrical parameters and pin configurations before substitution.
