0402HS-4N3EJTS

Fixed Inductors Overview

The Delta Electronics/Components 0402HS-4N3EJTS is a fixed surface-mount inductor from the 0402HS series. It features an unshielded drum core wirewound construction with a ceramic magnetic core. The component provides an inductance of 4.3 nH with a tolerance of ±5%. It has a DC resistance of 91 mΩ and a rated current of 700 mA. The self-resonant frequency is specified at 6 GHz, with a Q value of 14 measured at 250 MHz. The package dimensions are 1.27 mm in length, 0.76 mm in width, and a maximum seated height of 0.60 mm.

Fixed Inductors Feature Summary

• Unshielded drum core wirewound design for minimal parasitic effects
• High self-resonant frequency suitable for RF applications
• Compact 0402 footprint for dense PCB layouts

Fixed Inductors Applications

• RF matching networks
• DC-DC converter input/output filtering
• Signal line impedance matching

Fixed Inductors Procurement Notes

Verify the specific suffix JTS against official datasheets to confirm tolerance and packaging details. Ensure compatibility with standard reflow soldering profiles. Check RoHS compliance status as per the latest manufacturer documentation before integration into regulated products.

Fixed Inductors Selection Notes

Select this component when a low inductance value near 4.3 nH is required for high-frequency circuits. Consider the 700 mA current rating and 91 mΩ DCR for power loss calculations. The unshielded type may require careful layout to minimize electromagnetic interference coupling with nearby traces.

Fixed Inductors Part Context

This part belongs to the 0402HS series of fixed inductors manufactured by Delta Electronics/Components. The series offers various inductance values within the compact 0402 (1005 Metric) package, designed for applications requiring small form factors and reliable performance in consumer electronics and communication devices.

Fixed Inductors Replacement Considerations

Direct substitutes include other 0402HS series variants with similar electrical characteristics. Cross-reference with 0402HM-4N3EBTS or 0402HM-4N3EKTS if tighter tolerance or different packaging options are acceptable, noting differences in DCR and current ratings.
