Fixed Inductors Procurement Notes

Verify the exact suffix against official Delta documentation to confirm pinout and electrical tolerances. Confirm RoHS3 compliance status directly from the manufacturer datasheet before integration. Ensure the selected packaging format matches automated placement requirements. Cross-reference the DigiKey part number 2035-1465-2-ND for accurate sourcing details.

Fixed Inductors Selection Notes

Select this component when a compact 0402 footprint is required for low-inductance RF paths. The 140 mA current rating suits low-power signal lines rather than high-current power stages. Consider the 1.96 ohm DC resistance impact on voltage drop if used in sensitive biasing circuits. Verify that the 2.5 GHz self-resonant frequency aligns with the target operating band.

Fixed Inductors Part Context

This inductor belongs to the 0402HM series, which focuses on high-performance magnetic components for demanding environments. Delta Electronics supplies these passive components for sectors including IoT, automotive, and cloud infrastructure. The series emphasizes miniaturization while maintaining reliable electromagnetic characteristics for modern high-density PCB designs.
