• Impedance matching networks

Fixed Inductors Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with Pulse Electronics or authorized distributors before procurement. Confirm that the 0402 package dimensions align with your PCB footprint requirements. Ensure the 340 mA saturation current rating meets the operational DC bias conditions of your target application to prevent performance degradation.

Fixed Inductors Selection Notes

Select this component when a 420 nH inductance value is required in a minimal 0402 footprint. Consider the 1.1 Ohm DC resistance and 340 mA current limits against your circuit's power budget. The 700 MHz self-resonant frequency defines the upper operational limit for effective inductive behavior in high-frequency designs.
