0402HM-2N9EBTS

Fixed Inductors Overview

The 0402HM-2N9EBTS is a fixed surface-mount inductor from Delta Electronics/Components, featuring a drum core wirewound construction with a ceramic core. It offers an inductance of 2.9 nH with a tolerance of ±0.1nH and a DC resistance of 70 mΩ. The component supports a rated current of 750 mA and achieves a Q value of 25 at 250 MHz. Its self-resonant frequency reaches 10 GHz when tested at 100 MHz. Housed in a compact 0402 (1005 Metric) package measuring 1.15mm x 0.70mm x 0.60mm, it operates within a temperature range of -55°C to 125°C.

• Impedance matching circuits

Fixed Inductors Procurement Notes

Verify the specific suffix 'EBTS' against manufacturer documentation to confirm packaging type and tape specifications. Ensure compatibility with standard reflow soldering profiles defined in the datasheet. Confirm RoHS3 compliance status if required by project regulations. Cross-reference the DigiKey part number 2035-1423-2-ND for accurate ordering details and availability status.

Fixed Inductors Selection Notes

Select this component for designs requiring sub-5 nH inductance values with tight tolerances. The 750 mA current rating suits low-power RF stages. Consider the 70 mΩ DC resistance impact on circuit efficiency. The 10 GHz self-resonant frequency ensures operation well beyond typical RF bands. Verify that the unshielded design does not interfere with nearby sensitive components.

Fixed Inductors Part Context

This part belongs to the 0402HM series of fixed inductors from Delta Electronics/Components. The series utilizes ceramic cores and wirewound technology to deliver consistent performance in small form factors. Similar parts in the series include 0402HM-3N9EBTS and 0402HM-4N3EBTS, which offer slightly higher inductance values while maintaining comparable physical dimensions and electrical characteristics.

Fixed Inductors Replacement Considerations

Direct substitutes within the same series include 0402HM-3N9EBTS and 0402HM-4N3EBTS, though these have different inductance values. For identical 2.9 nH specifications, verify equivalent parts from other manufacturers such as Murata or TDK that match the 0402 package and electrical parameters.
