Procurement Notes

Verify the specific datasheet version for the B82721K2701N020 to confirm exact dimensional tolerances and RoHS compliance status. Ensure the supplier provides original manufacturer documentation to validate the 10 mH inductance and 700 mA current rating specifications against potential variant differences within the B82721K series.

Selection Notes

Select this component when designing circuits requiring common-mode chokes with a nominal inductance near 10 mH. Consider the 700 mA current rating and 0.55 Ohm DC resistance for thermal management. Verify that the radial through-hole package fits the PCB layout constraints and that the operating temperature range meets the environmental requirements of the target application.
