Procurement Notes
Verify the specific package type and lead configuration against the official datasheet before integration. Confirm that the 10 A current rating aligns with the thermal management design of the target PCB. Ensure compliance with RoHS directives if required by the end product specifications. Cross-reference the impedance characteristics at the target frequency to validate EMI suppression effectiveness.
Selection Notes
Select this component when high current capacity and low DCR are critical for power line integrity. The WE-CMB HC series offers enhanced performance compared to standard variants. Consider the through-hole form factor for mechanical stability in high-vibration environments. Evaluate the 175 µH inductance value against the specific noise frequencies requiring attenuation in the circuit design.
Part Context
This part belongs to the WE-CMB HC series from Würth Elektronik, specialized for high-current common mode chokes. The series is engineered for robust electromagnetic interference suppression in power circuits. It complements other WE-CMB variants by offering higher current ratings and lower resistance profiles for demanding industrial and automotive applications.
Replacement Considerations
Check for direct substitutes within the WE-CMB HC series with matching 175 µH inductance and 10 A rating. Verify pin compatibility and physical dimensions for existing footprints. Ensure equivalent thermal and electrical performance metrics before substitution.
