BSPQ000603043N9B00

Fixed Inductors Overview

The BSPQ000603043N9B00 is an unshielded thick film fixed inductor from Pulse Electronics, housed in a 0201 (0603 metric) surface-mount package. It features a nominal inductance of 3.9 nH with a tolerance of ±0.1 nH. The component has a maximum DC resistance of 170 mΩ and a rated current of 500 mA. It operates within a temperature range of -55°C to +125°C, exhibits a Q value of 20 at 500 MHz, and achieves a self-resonant frequency of 7 GHz.

Fixed Inductors Feature Summary

• Unshielded thick film construction for minimal magnetic interference
• Compact 0201 footprint suitable for high-density PCB layouts
• High self-resonant frequency supporting RF applications

Fixed Inductors Applications

• RF circuit matching networks
• High-frequency signal filtering
• Impedance matching in communication modules

Fixed Inductors Procurement Notes

Verify the manufacturer part number against official Pulse Electronics documentation to ensure authenticity. Confirm that the specific suffix matches the required electrical parameters, as variations may exist within the series. Check RoHS compliance status and packaging options such as tape and reel or cut tape directly from authorized distributors to align with production requirements.

Fixed Inductors Selection Notes

Select this component when a low-inductance, unshielded solution is required for RF paths. The 0201 size constrains physical space, while the 500 mA rating defines current handling limits. Ensure the 170 mΩ DCR fits the power loss budget and verify that the 7 GHz self-resonant frequency exceeds the operating band to maintain inductive behavior.

Fixed Inductors Part Context

This part belongs to the BSPQ series of fixed inductors designed for general-purpose RF applications. It utilizes ceramic core technology and thick film manufacturing processes. The series offers various inductance values within the same compact package, allowing designers to scale performance without altering the board footprint.

Fixed Inductors Replacement Considerations

Direct substitutes include Murata LQP03HQ3N8B02D and Chilisin BSPQ000603043N0B00, provided their electrical parameters align with the design requirements. Verify package dimensions and pin compatibility before substitution.
