Procurement Notes
Verify the specific suffix N040 against official TDK EPCOS documentation to confirm surface mount packaging and lead-free status. Ensure the ordered part matches the 12mH inductance and 300mA rating requirements. Cross-reference the manufacturer's latest datasheet for any updates on material composition or environmental compliance standards prior to procurement.
Selection Notes
Select this component when surface mount assembly is required for power line chokes. It is suitable for applications needing 12mH inductance at 300mA with high thermal stability up to 125°C. Consider the physical dimensions and footprint compatibility with the PCB layout. Verify that the 250V AC rated voltage meets the circuit's operational requirements.
Part Context
This component belongs to the B82720A/K series of current-compensated ring core double chokes manufactured by EPCOS (TDK). The series offers various inductance and current ratings for power line filtering. These chokes are characterized by their compact size and robust construction using ferrite cores and polycarbonate cases, making them suitable for dense PCB layouts.
Replacement Considerations
Check for direct substitutes within the B82720S series with identical electrical parameters. Verify pinout and mechanical dimensions before substitution. Consult official TDK EPCOS cross-reference lists for approved alternatives.
