• High self-resonant frequency for RF signal integrity
• Low DC resistance to minimize power loss

Applications

• RF matching networks
• DC-DC converter filters
• General-purpose filtering in mobile devices

Procurement Notes

Verify the specific suffix '315' against official NXP documentation to confirm tape-and-reel packaging specifications and quantity per reel. Ensure the ordering part number matches the exact inductance tolerance and current rating required for your circuit design before finalizing procurement.

Selection Notes

Select this component when a small form factor is critical for RF or power line filtering. Compare the 18 nH value against circuit simulation requirements to ensure it meets the target impedance and resonance characteristics. Verify that the 150 mA current rating aligns with the peak currents in the application.

Part Context

This inductor belongs to NXP's portfolio of passive components, often utilized in conjunction with their semiconductor solutions for consumer electronics and automotive systems. It complements active components by providing necessary signal conditioning and noise suppression in compact electronic assemblies.

Replacement Considerations

Check for direct cross-reference part numbers from NXP or other manufacturers offering identical 18 nH, 0402 package inductors with comparable SRF and current ratings. Ensure any substitute maintains the same physical dimensions and electrical performance metrics.
