0603HP-4N7EJTS

Fixed Inductors Overview

The 0603HP-4N7EJTS is a fixed surface-mount inductor from Delta Electronics/Components, featuring a 4.7 nH nominal inductance with ±5% tolerance. It utilizes an unshielded drum core wirewound construction with a ceramic core material. The component supports a current rating of 1.1 A and exhibits a DC resistance (DCR) of 100 mΩ. Electrical performance includes a self-resonant frequency of 7.9 GHz and a Q factor of 25 measured at 250 MHz. Designed for high-frequency applications, it operates within a temperature range of -40°C to +125°C and is housed in a standard 0603 (1.60mm x 0.80mm) package.

Fixed Inductors Procurement Notes

Verify the specific suffix 'J' confirms the ±5% tolerance requirement against your schematic specifications. Ensure the 0603 footprint dimensions align with your PCB land pattern guidelines. Confirm RoHS3 compliance status if required by your regional manufacturing regulations. Cross-reference the manufacturer part number directly with official Delta Electronics documentation to avoid counterfeit components.

Fixed Inductors Selection Notes

Select this component when low inductance values are required for high-frequency signal integrity. The unshielded construction necessitates careful layout planning to prevent crosstalk with adjacent traces. Evaluate the 1.1 A current rating against peak operational loads to ensure thermal reliability. Consider the 7.9 GHz self-resonant limit to maintain inductive behavior within the target operating band.

Fixed Inductors Part Context

This part belongs to the 0603HP series of high-performance chip inductors designed for compact electronic assemblies. The series offers various inductance values optimized for RF and microwave applications. Delta Electronics manufactures these components using precision wirewinding techniques on ceramic cores to achieve consistent electrical characteristics in small form factors.

Fixed Inductors Replacement Considerations

Direct substitutes include other 0603 package inductors with identical 4.7 nH inductance, ±5% tolerance, and similar current ratings. Verify that alternative parts match the 100 mΩ DCR and 7.9 GHz self-resonant frequency specifications. Ensure the replacement maintains the same unshielded drum core construction to preserve electromagnetic compatibility.
