0402HP-400EHTS

Fixed Inductors Overview

The 0402HP-400EHTS is a fixed wirewound inductor from Delta Electronics/Components, featuring an unshielded drum core design. It offers an inductance of 40 nH with a tolerance of ±5%. The component supports a rated current of 450 mA and exhibits a DC resistance of 430 mΩ. It operates within a temperature range of -40°C to 125°C and has a self-resonant frequency of 3 GHz. Packaged in a compact 0402 (1005 metric) surface-mount footprint, it is suitable for high-frequency applications requiring precise impedance control.

Fixed Inductors Feature Summary

• Unshielded drum core construction minimizes magnetic interference
• High self-resonant frequency ensures stability at RF ranges
• Compact 0402 surface-mount package enables dense PCB layouts

Fixed Inductors Applications

• RF matching networks
• DC-DC converter input/output filtering
• Signal line chokes in high-speed digital circuits

Fixed Inductors Procurement Notes

Verify the specific suffix 'EHTS' against official Delta Electronics documentation to confirm tape-and-reel packaging and material composition. Ensure compatibility with standard reflow soldering profiles for 0402 components. Cross-reference RoHS3 compliance status directly with the manufacturer's latest datasheet before integration into regulated assemblies.

Fixed Inductors Selection Notes

Select this component when low inductance values near 40 nH are required in minimal space. Consider the 430 mΩ DC resistance impact on power efficiency. Compare against the 0402HM series if higher current ratings or different Q-factor characteristics are needed for the specific circuit topology.

Fixed Inductors Part Context

This part belongs to the 0402HP series of fixed inductors designed for general-purpose high-frequency applications. It shares the standard 0402 footprint with other variants but differs in inductance value and current handling capabilities. The HP series typically targets cost-sensitive consumer electronics and communication devices requiring reliable passive components.

Fixed Inductors Replacement Considerations

Direct substitutes include other 40 nH ±5% inductors in 0402 packages from manufacturers like Murata or TDK. Verify that replacement parts match the 450 mA current rating and 430 mΩ DCR specifications to maintain circuit performance.
