Fixed Inductors Procurement Notes

Verify the specific manufacturer part number against official Wurth Elektronik documentation to ensure authenticity. Confirm that the received components match the 1008 package dimensions and electrical specifications. Check for any relevant RoHS or REACH compliance certificates required for your manufacturing process. Ensure storage conditions adhere to moisture sensitivity level guidelines to prevent damage before soldering.

Fixed Inductors Selection Notes

Select this component when an unshielded inductor is required to minimize magnetic interference with nearby sensitive circuits. The 1008 footprint offers a balance between current handling and board space efficiency. Consider the 230 mA current rating and 1.3 Ohm resistance limits to ensure they align with the target circuit's power budget and signal integrity requirements.

Fixed Inductors Part Context

This part belongs to the WE-RFI series, which focuses on radio frequency inductors. The series utilizes wirewound technology with ferrite cores to achieve stable inductance values at high frequencies. The 1008 package size is common in compact consumer electronics and industrial control boards where space constraints are critical but moderate current levels are sufficient.

Fixed Inductors Replacement Considerations

The 744762315A is a similar unshielded wirewound inductor from the same series but offers 1.5 µH inductance and a 1008 package. Verify if the higher inductance value meets the circuit requirements before substitution.
