Fixed Inductors Procurement Notes

Verify the manufacturer part number 7447783102 against official Wurth Elektronik documentation to ensure authenticity. Confirm that the received components match the specified 1 mH inductance and 230 mA current ratings. Check for physical damage to the surface mount terminals. Ensure storage conditions comply with moisture sensitivity levels defined in the datasheet to maintain solderability and electrical performance upon installation.

Fixed Inductors Selection Notes

Select this component when a compact shielded inductor is required for automotive or industrial applications. The 1 mH value suits low-frequency filtering needs. The 230 mA rating limits suitability for high-current power stages. Consider the 4.6 Ohm DC resistance for efficiency calculations. Verify footprint compatibility with the 7.3 mm by 7.4 mm dimensions before integration into the PCB layout.
