Fixed Inductors Procurement Notes

Verify the obsolete status of this component before procurement planning. The manufacturer issued an obsolescence notice on July 26, 2024. Confirm availability through authorized distributors or secondary market suppliers. Ensure that any replacement strategy accounts for the discontinuation timeline to prevent supply chain interruptions for existing production lines.

Fixed Inductors Selection Notes

Select this inductor when a low-inductance value near 30 nH is required for high-frequency signal paths. The unshielded design minimizes parasitic capacitance but may require careful layout to avoid electromagnetic interference. Verify that the 270 mA current rating meets the circuit's peak current demands. Consider the ±2% tolerance for precision tuning requirements in resonant circuits.

Fixed Inductors Part Context

This component belongs to the 0402HM series of fixed inductors manufactured by Delta Electronics/Components. The series offers various inductance values in the same 0402 package, allowing for standardized inventory management across different circuit designs. The HM designation typically indicates specific performance characteristics tailored for high-frequency applications within the company's portfolio.

Fixed Inductors Replacement Considerations

The part is officially obsolete as of July 26, 2024. No direct substitute part numbers are publicly confirmed by the manufacturer. Engineers must evaluate alternative vendors offering similar 30 nH, 0402, unshielded wirewound inductors with comparable Q factors and current ratings.
