LTF0402ST3N9

Fixed Inductors Overview

The LTF0402ST3N9 is a surface-mount RF inductor manufactured by Stackpole Electronics Inc. It features an inductance of 3.9 nH with a tolerance of ±0.3%. The component operates within a current rating of 340 mA and utilizes a 0402 (1005 metric) package measuring 1.00 mm x 0.50 mm. It is designed for high-frequency applications requiring precise inductive values.

Fixed Inductors Feature Summary

• Ultra-low inductance value of 3.9 nH for high-frequency signal processing
• Tight tolerance of ±0.3% ensures precise circuit performance
• Compact 0402 surface-mount footprint for space-constrained designs

Fixed Inductors Applications

• High-frequency filtering circuits
• Impedance matching stages

Fixed Inductors Procurement Notes

Verify the specific suffix ST against the manufacturer datasheet to confirm tolerance and current ratings. Ensure the 0402 package dimensions align with PCB land patterns. Confirm RoHS compliance status if required by project specifications before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when sub-5 nH inductance is critical for RF tuning. The tight 0.3% tolerance makes it suitable for precision applications where standard tolerances are insufficient. Evaluate the 340 mA current limit against peak circuit currents to prevent saturation or thermal issues during operation.
