0402HM-2N9EKTS

Fixed Inductors Overview

The Delta Electronics 0402HM-2N9EKTS is an unshielded drum core wirewound fixed inductor housed in a compact 0402 (1005 metric) surface-mount package. It provides a nominal inductance of 2.9 nH with a tolerance of ±10%. The component supports a rated current of 750 mA and exhibits a maximum DC resistance of 70 mΩ. It operates within a temperature range of -55°C to 125°C and features a self-resonant frequency of 15 GHz, ensuring performance stability in high-frequency applications.

Fixed Inductors Feature Summary

• Utilizes a ceramic drum core construction for stable inductance characteristics
• Designed for high-speed signal integrity with minimal parasitic effects
• Supports surface mount assembly for automated manufacturing processes

Fixed Inductors Applications

• RF matching networks in wireless communication modules
• Impedance matching circuits for high-frequency data interfaces
• Decoupling applications in RF power amplifiers

Fixed Inductors Procurement Notes

Verify the manufacturer part number against official Delta Electronics documentation to ensure authenticity. Confirm that the received components match the specified 0402 package dimensions and electrical parameters. Check for RoHS3 compliance markings as indicated in the product specifications. Ensure storage conditions adhere to moisture sensitivity level requirements before reflow soldering.

Fixed Inductors Selection Notes

Select this component when a very low inductance value near 3 nH is required for RF circuit tuning. The 750 mA current rating makes it suitable for power-sensitive RF stages. The unshielded design allows for flexible PCB layout but requires consideration of mutual inductance if placed in close proximity to other components.

Fixed Inductors Part Context

This inductor belongs to the 0402HM series from Delta Electronics/Components, which focuses on high-performance passive components for demanding electronic applications. The series offers various inductance values optimized for RF and microwave frequencies, providing engineers with standardized options for impedance control and signal filtering in compact form factors.

Fixed Inductors Replacement Considerations

Consult Delta Electronics official cross-reference lists for verified substitutes. Ensure any replacement maintains the 0402 footprint, 2.9 nH nominal value, and 750 mA current handling capability without altering the circuit's RF performance characteristics.
