Fixed Inductors Procurement Notes

Verify the specific ordering suffix 'RW' against the manufacturer's official documentation to confirm tape-and-reel packaging specifications. Ensure that the selected variant aligns with required handling and storage conditions defined in the datasheet. Cross-reference the part number with the latest Coilcraft catalog to confirm availability status and any potential supply chain restrictions before finalizing procurement plans.

Fixed Inductors Selection Notes

Select this component when space-constrained designs require high-current performance in a 0402 footprint. The 3.3 µH value suits applications needing moderate inductance with strict size limitations. Consider the 150 mA current rating and 2.2 Ohm resistance for thermal management. Verify compatibility with operating temperatures up to 125°C and ensure the unshielded design does not interfere with nearby sensitive circuitry.

Fixed Inductors Part Context

This part belongs to the 0402DF series, which specializes in low-resistance ferrite chip inductors. The series ranges from 15 nH to 1 mH, offering high current handling capabilities. These components are engineered for ground-to-ground applications and provide high impedance for RF isolation. The 0402DF line emphasizes miniaturization while maintaining robust electrical performance for demanding environments.
