Procurement Notes

Verify the manufacturer part number against official API Delevan documentation to confirm specifications. Ensure compatibility with PCB footprint dimensions and thermal requirements. Check for recent Product Change Notifications (PCN) regarding material or manufacturing updates before finalizing procurement.

Selection Notes

Select this component for designs requiring precise 47 µH inductance with tight tolerance in RF environments. Consider the low rated current of 70 mA and high DC resistance when designing power-sensitive circuits. Verify that the unshielded design does not interfere with nearby sensitive components due to magnetic field exposure.

Part Context

This component belongs to the 106 series of fixed surface-mount inductors manufactured by API Delevan Inc.
