Procurement Notes
Verify the exact part number against official TT Electronics documentation before procurement. Confirm that the specific suffix matches the required electrical characteristics. Check current availability status as components may be subject to supply constraints or end-of-life notifications. Ensure compatibility with existing PCB footprint and reflow soldering profiles.
Selection Notes
Select this component when designing circuits requiring high current capacity with minimal impedance. The 680 nH value suits high-frequency switching applications where low inductance is necessary. Consider the 35 A current rating to ensure thermal stability under peak load conditions. Verify that the surface-mount package fits within the available board space constraints.
Part Context
This inductor belongs to the HM72E-12 series, which comprises high-power molded surface-mount inductors. The series is designed for demanding power electronics applications requiring robust performance. Similar parts in the series include variations with different inductance values such as 10 uH or 20 uH, maintaining similar physical dimensions and current handling capabilities.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Designers should consult official manufacturer resources for potential cross-references or alternative components if this specific part becomes unavailable.
