Procurement Notes
Verify the specific suffix against official EPCOS/TDK documentation to confirm exact electrical characteristics, as variations exist within the B82725A series. Ensure the required inductance and current ratings match the application needs before procurement. Cross-reference the manufacturer's latest datasheet for any updates on compliance or packaging standards.
Selection Notes
Select this component when a high-current, low-DCR solution is required for 250 V AC power lines. The 8 A rating and compact horizontal footprint make it suitable for space-constrained industrial and consumer designs. Evaluate thermal performance within the -40°C to 125°C operating range to ensure reliability under load.
Part Context
This part belongs to the B82725A series of power line chokes from EPCOS (TDK). The series offers various inductance and current combinations for common mode noise suppression. These components are widely used in environments requiring robust EMI filtering for mains-powered devices.
Replacement Considerations
Check for direct substitutes within the B82725A series with matching 3.9 mH inductance and 8 A current ratings. Verify pin compatibility and physical dimensions for existing PCB layouts.
