Fixed Inductors Procurement Notes

Verify the specific manufacturer designation, as the part number may be associated with either Bel Signal Transformer or Signal Transformer depending on the source. Confirm RoHS compliance status and check for end-of-life notifications prior to procurement. Ensure the supplier provides official datasheets matching the exact suffix to guarantee electrical parameter accuracy.

Fixed Inductors Selection Notes

Select this component when a 22 µH inductance value is required with a saturation current of at least 3.6 A. The 43.2 mΩ DC resistance supports efficient power transfer. Verify that the 12.5 mm x 12.5 mm footprint fits the board layout constraints and that the 6 mm height clearance is available for the application environment.
