Procurement Notes
Verify the specific ordering suffix against the official TDK Electronics datasheet to confirm exact electrical tolerances and packaging specifications. Ensure compatibility with existing board layouts regarding lead spacing and thermal requirements before finalizing procurement decisions.
Selection Notes
Select this component when dual-line current compensation is required for power line applications. The 47 mH inductance at 10 kHz suits moderate frequency filtering needs. Confirm that the 500 mA current rating aligns with the operational load to prevent saturation or excessive heating during continuous use.
Part Context
This part belongs to the B82731 series of fixed inductors from EPCOS (TDK Electronics). The series encompasses various current-compensated chokes designed for power line applications. The H2501A030 designation specifies the unique inductance, tolerance, and packaging configuration within this product family.
Replacement Considerations
Consult the official TDK Electronics replacement guide for verified substitute part numbers. Cross-reference inductance values, current ratings, and physical dimensions to ensure functional equivalence without compromising circuit performance.
