0402HM-9N5EHTS

Fixed Inductors Overview

The Delta Electronics/Components 0402HM-9N5EHTS is a fixed surface-mount inductor from the 0402HM series. It features an unshielded drum core wirewound design with a ceramic core, housed in a compact 0402 (1005 Metric) package measuring 1.15mm x 0.70mm x 0.60mm. The component provides an inductance of 9.5 nH with a tolerance of ±3%. It supports a rated current of 540 mA and exhibits a DC resistance of 140 mOhm. Electrical performance includes a Q value of 25 at 250 MHz and a self-resonant frequency of 5.5 GHz. It operates within a temperature range of -55°C to 125°C.

Fixed Inductors Feature Summary

• Unshielded drum core wirewound construction for minimal magnetic interference
• High self-resonant frequency capability suitable for RF applications
• Compact 0402 footprint optimized for high-density surface mount layouts

Fixed Inductors Applications

• RF matching networks
• DC-DC converter output filtering
• High-frequency signal coupling

Fixed Inductors Procurement Notes

Verify the specific suffix 'HTS' against project requirements, as it denotes tape-and-reel packaging distinct from cut tape or Digi-Reel options. Confirm that the 540 mA rated current aligns with peak load conditions. Ensure the 140 mOhm DC resistance meets power loss constraints. Check RoHS3 compliance status if required by regional regulations. Validate lead times due to potential supply variability.

Fixed Inductors Selection Notes

Select this component when a low-inductance value near 9.5 nH is required in a standard 0402 envelope. Consider the unshielded nature for applications where magnetic field interaction must be minimized. Compare the 5.5 GHz self-resonant frequency against circuit operating frequencies to ensure effective impedance characteristics. Evaluate thermal management needs given the -55°C to 125°C operational range.

Fixed Inductors Part Context

This part belongs to the 0402HM series of fixed inductors manufactured by Delta Electronics/Components. The series utilizes ceramic drum cores to achieve stable inductance values in miniature packages. The 0402HM designation indicates a specific size and performance tier within the manufacturer's portfolio, targeting high-frequency electronics and portable device designs requiring small form factors.

Fixed Inductors Replacement Considerations

Direct substitutes include the 0402HM-9N5EGTS, which shares identical electrical parameters but differs in packaging type. Other variants within the 0402HM series may offer different tolerances or current ratings. Verify pin compatibility and mechanical dimensions before substitution.
