Procurement Notes
Verify the specific datasheet version and RoHS compliance status prior to procurement. Confirm that the through-hole mounting style and physical dimensions align with the target PCB layout requirements. Ensure the operating temperature range meets the environmental conditions of the final assembly.
Selection Notes
Select this component when a high-current common mode choke with low DC resistance is required for through-hole implementation. The 65 µH inductance value is optimized for specific frequency ranges. Evaluate the 5 A current rating against the peak load requirements of the circuit to ensure reliable operation without saturation.
Part Context
This part belongs to the WE-CMB Power Type S series, which focuses on high-performance common mode chokes for power applications. The series is characterized by its ability to handle significant currents while maintaining low insertion loss. It serves as a critical EMI filter component in modern electronic designs requiring strict noise control.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify electrical parameters such as inductance, current rating, and DC resistance when evaluating alternative components from other manufacturers.
