Procurement Notes

Verify availability status carefully as this part is scheduled for obsolescence and will be discontinued by the manufacturer. Confirm that the specific ordering suffix matches required documentation standards. Ensure compatibility with existing PCB footprints before finalizing procurement decisions due to end-of-life constraints.

Selection Notes

Select this component when a 330 µH inductance value is required with a compact 12.5 x 12.5 mm footprint. Consider the 830 mA current rating for power management designs. Verify thermal requirements against the -40°C to +85°C operating range. Compare against alternative values in the B953AS series if different inductance or current ratings are needed.

Part Context
