Fixed Inductors Procurement Notes

This component is officially designated as obsolete or not recommended for new designs by TDK. Procurement should focus on verifying end-of-life status through official Product Change Notices. Engineers must confirm availability of valid replacement parts before finalizing designs to ensure long-term supply chain stability.

Fixed Inductors Selection Notes

Select this part only if legacy compatibility is required, as it has been superseded by newer series. Verify that the 1 µH inductance and 8.9 A saturation current meet specific circuit requirements. Ensure the PCB footprint matches the 7x7 mm package dimensions and account for thermal management due to the high current rating.

Fixed Inductors Part Context

The LGJ series represents TDK's line of shielded power inductors tailored for harsh automotive environments. This specific model utilizes a robust drum core structure to maintain performance under high current loads. It is part of a broader family of components designed to support electric vehicle and advanced driver-assistance system architectures.

Fixed Inductors Replacement Considerations

Official substitutes include CLF7045NIT-1R0N-D and CLF6045NIT-1R0N-D. These alternatives offer similar inductance values but may differ in physical dimensions or current ratings. Validate pinout compatibility and thermal characteristics when transitioning to these replacement parts.
