0402HM-270EKTS

Fixed Inductors Overview

The 0402HM-270EKTS is a fixed surface-mount inductor from Delta Electronics/Components, featuring an unshielded drum core and wirewound construction. It offers an inductance of 27 nH with a tolerance of ±10%. The component supports a rated current of 280 mA and exhibits a DC resistance of 520 mOhm. Electrical performance includes a Q value of 25 at 250 MHz and a self-resonant frequency of 4 GHz. Designed for operation between -55°C and 125°C, it utilizes a ceramic core within a compact 0402 (1005 metric) package measuring 1.15mm x 0.70mm.

Fixed Inductors Feature Summary

• Unshielded drum core wirewound design for high-frequency signal integrity
• Compact 0402 footprint suitable for dense surface-mount layouts
• High self-resonant frequency capability up to 4 GHz
• Robust thermal stability across extended industrial temperature ranges

Fixed Inductors Applications

• RF matching networks in mobile communication devices
• Impedance matching circuits in wireless transceivers
• Filtering components in high-speed digital interfaces
• Bias tees and RF signal conditioning modules

Fixed Inductors Procurement Notes

Verify the specific ordering suffix EKTS to ensure correct packaging configuration. Confirm that the selected variant matches the required RoHS3 compliance status for environmental regulations. Cross-reference the manufacturer part number against official distribution channels to avoid counterfeit components. Ensure storage conditions align with MSL Level 1 requirements to maintain component reliability prior to assembly.

Fixed Inductors Selection Notes

Select this component when circuit designs require low inductance values under 30 nH for high-frequency applications. The unshielded structure minimizes magnetic interference but requires careful layout planning to prevent crosstalk. Evaluate the 280 mA current rating against peak operational loads to prevent saturation. Consider the 520 mOhm DCR impact on power efficiency within the specific circuit topology.

Fixed Inductors Part Context

This part belongs to the 0402HM series of fixed inductors manufactured by Delta Electronics/Components. The series specializes in ultra-small form factor components optimized for high-frequency performance. It shares the 0402 package dimensions with other variants in the lineup but differs in inductance and current handling capabilities based on internal winding specifications.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 27 nH inductance, 0402 package, and similar electrical parameters. Verify compatibility with existing PCB footprints and reflow soldering profiles. Consult manufacturer cross-reference lists for equivalent parts with identical Q-factor and self-resonant frequency characteristics.
