Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct electrical parameters and packaging. Confirm that the component matches the required inductance and current ratings for your specific circuit design. Check for any RoHS compliance statements or material declarations if required by your procurement standards. Ensure the mounting style aligns with your PCB layout constraints.

Selection Notes

Select this component when a high inductance value of 49 mH is required for power line filtering. Consider its horizontal mounting profile and physical dimensions to ensure adequate clearance on the PCB. Evaluate the 2.8 A current rating against the maximum load current of your application. Verify compatibility with the operating temperature range of -40°C to +125°C for your environmental conditions.

Part Context

This part belongs to the B82724A/J series of current-compensated ring core double chokes manufactured by EPCOS (TDK). These components are specifically engineered for power line applications, offering reliable common mode noise attenuation. The series is characterized by its robust construction and suitability for demanding industrial and automotive environments where stable performance over a wide temperature range is critical.

Replacement Considerations

Consult the official EPCOS/TDK replacement guide for direct substitutes. Ensure any alternative component matches the 49 mH inductance, 2.8 A current rating, and 250 V AC voltage rating. Verify that the replacement maintains the same horizontal through-hole mounting configuration and similar physical dimensions to fit existing PCB footprints without modification.
