Procurement Notes

Verify the specific suffix against official TDK/EPCOS documentation to confirm exact electrical tolerances and material compliance status. Ensure the ordering code matches the required inductance value of 47 mH and rated current specifications. Cross-reference the package dimensions with PCB layout requirements before finalizing procurement orders.

Selection Notes

Select this component for applications requiring high inductance values in a compact rectangular form factor. The 47 mH rating supports effective low-frequency noise attenuation. Verify that the 2.5 Ω DC resistance aligns with system power loss constraints. Confirm compatibility with standard through-hole assembly processes given the terminal configuration.

Part Context

This component belongs to the B82722 series of power line chokes designed for AC voltage ratings up to 250 V. The series offers various inductance options ranging from 1.2 mH to 68 mH. These chokes are engineered for current-compensated operation, making them suitable for differential mode noise reduction in single-phase power supplies.
