Procurement Notes
Verify the specific part number against official manufacturer documentation to ensure compatibility with design requirements. Confirm that the through-hole footprint dimensions and pin spacing match the target PCB layout. Check for RoHS compliance status if environmental regulations apply to the final assembly. Ensure the operating temperature range meets the system's thermal conditions.
Selection Notes
Select this component when a two-line common mode choke with 5.6 mH inductance is required for power line applications. Consider the 600 mA current rating and 830 milliohm DCR to ensure it fits the circuit's electrical constraints. The through-hole format is suitable for manual assembly or specific automated processes requiring this package type. Evaluate the physical size constraints against the available board space.
Part Context
This component belongs to the WE-TFCH series of common mode chokes manufactured by Würth Elektronik.
