Procurement Notes
This component is officially classified as obsolete or end-of-life by the manufacturer. Procurement should focus on verifying stock availability through authorized distributors or secondary market suppliers. Due to its discontinued status, long-term supply continuity cannot be guaranteed, and alternative sourcing strategies must be evaluated immediately.
Selection Notes
Engineers selecting this part must account for its obsolete lifecycle status. While it offers specific high-current performance characteristics, reliance on this component poses risks for future production runs. Design reviews should prioritize identifying equivalent components that remain in active production to ensure sustainable manufacturing capabilities.
Part Context
The HM72B series represents a line of high-performance molded surface mount inductors. These components are characterized by their ability to handle significant power levels within a compact footprint. The HM72B-06R22LFTR13 specifically utilizes a 2.2 µH value within this family, targeting applications where space constraints and high current density are critical design factors.
Replacement Considerations
As the HM72B-06R22LFTR13 is obsolete, direct substitutes may not be available from the original manufacturer. Engineers should evaluate other SMD power inductors with similar 2.2 µH inductance and comparable current ratings. Cross-referencing physical dimensions and saturation characteristics is essential when selecting replacement parts.
