Procurement Notes

Verify the specific datasheet revision and safety certifications required for your application. Confirm that the 33 A current rating and 420 µH inductance align with your circuit design parameters. Ensure mechanical compatibility with your assembly process, as this is a through-hole component. Cross-reference the manufacturer's latest documentation for any updates on material compliance or packaging specifications before finalizing procurement.

Selection Notes

Select this component when high current handling capability is required alongside significant common-mode noise attenuation. The 420 µH value offers substantial impedance at switching frequencies. Consider the physical size and through-hole mounting requirements during layout planning. Evaluate thermal performance under continuous load conditions to ensure reliability in high-power density designs.

Part Context

This component belongs to the B82726 series of current-compensated chokes from EPCOS/TDK. These devices are engineered for robust performance in demanding power electronics applications. The series utilizes ring core technology to achieve high saturation currents while maintaining compact form factors relative to their electrical ratings.

Replacement Considerations

Consult official TDK Electronics substitution guides for verified alternatives. Ensure replacement parts match the 420 µH inductance, 33 A current rating, and through-hole package dimensions. Verify equivalent safety approvals and material composition for direct interchangeability.
