Procurement Notes

Verify the specific suffix U030 against official EPCOS/TDK documentation to confirm packaging details such as reel or cut tape configuration. Ensure the voltage rating aligns with system requirements before procurement. Cross-reference the part number with authorized distributors to guarantee authenticity and traceability.

Selection Notes

Select this component when a compact, high-inductance common mode choke is required for low-current applications. The 500 mA rating suits sensitive signal lines or low-power stages. Verify that the radial lead spacing fits the target PCB layout constraints.

Part Context

This component belongs to the B82721 series of power line chokes from EPCOS (TDK). The series offers various inductance values tailored for different current compensation needs. These chokes are widely used in consumer electronics and industrial devices to meet EMC standards.

Replacement Considerations

Check for direct substitutes within the B82721 series with compatible inductance and current ratings. Verify pin-out compatibility and dimensional constraints before substituting with other manufacturers' common mode chokes.
