0402HP-2N7EJTS

Fixed Inductors Overview

The 0402HP-2N7EJTS is a fixed surface-mount inductor from Delta Electronics/Components, featuring a 2.7 nH nominal inductance with ±5% tolerance. It utilizes an unshielded drum core wirewound design with a ceramic magnetic core, housed in a compact 0402 (1005 Metric) package measuring 1.15mm x 0.70mm x 0.60mm max. The component supports a rated current of 1.5 A and exhibits a DC resistance of 56 mΩ. It operates within a temperature range of -40°C to 125°C, achieving a self-resonant frequency of 13 GHz at a test frequency of 250 MHz.

Fixed Inductors Feature Summary

• Unshielded drum core wirewound construction for high-frequency RF applications
• Compact 0402 footprint enabling dense surface mount layouts
• High self-resonant frequency of 13 GHz for signal integrity

Fixed Inductors Applications

• RF circuit filtering and impedance matching
• High-speed digital signal line decoupling
• Mobile device power management circuits

Fixed Inductors Procurement Notes

Verify the manufacturer part number against official Delta Electronics documentation to ensure authenticity. Confirm that the specific suffix matches the required electrical parameters, as variations may exist within the series. Check RoHS compliance status and moisture sensitivity level requirements prior to assembly to prevent handling damage during reflow soldering processes.

Fixed Inductors Selection Notes

Select this component when a low-inductance value near 2.7 nH is required for high-frequency performance. The unshielded design minimizes parasitic capacitance but requires careful layout to avoid magnetic interference with nearby components. Ensure the PCB land pattern matches the 0402 dimensions and that the operating current does not exceed the 1.5 A rating to maintain thermal stability.

Fixed Inductors Part Context

This part belongs to the 0402HP series of high-performance fixed inductors designed for demanding RF and microwave applications. The series emphasizes miniaturization while maintaining stable inductance values at high frequencies. The HP designation typically indicates optimized characteristics for high-frequency operation compared to standard general-purpose inductors in the same package size.

Fixed Inductors Replacement Considerations

Direct substitutes include other 0402 unshielded wirewound inductors with 2.7 nH ±5% tolerance, 1.5 A current rating, and similar DCR. Verify that alternative manufacturers offer comparable self-resonant frequencies and thermal ratings to ensure equivalent RF performance and reliability in the final application.
