Provides current-compensated filtering for balanced line applications
Engineered for high reliability in power supply and voltage regulation circuits

Applications

Power supplies
Battery chargers
Portable devices

Procurement Notes

Verify the specific suffix A030 against official TDK documentation to confirm lead frame material and termination finish. Ensure the procurement channel provides traceability to EPCOS/TDK manufacturing records. Cross-reference the part number with the latest datasheet to confirm compliance with RoHS standards and absence of prohibited substances before finalizing orders.

Selection Notes

Select this component when designing circuits requiring 47 mH common mode rejection at low frequencies. The 500 mA rating suits moderate current applications. Verify that the physical dimensions fit the PCB layout constraints. Confirm thermal management requirements align with the specified operating temperature range under expected load conditions.

Part Context

This component belongs to the B82731 series of current-compensated D-core double chokes. These components are designed for general-purpose noise suppression in electronic equipment. The series offers standardized mechanical footprints and electrical characteristics suitable for various consumer and industrial electronics applications.

Replacement Considerations

Consult official TDK substitution guides for verified equivalents. Generic cross-references may not match the specific D-core geometry or magnetic properties required for optimal performance in sensitive circuits.
