0402HP-190EHTS

Fixed Inductors Overview

The Delta Electronics/Components 0402HP-190EHTS is a fixed wirewound inductor with a ceramic drum core, housed in an unshielded 0402 (1005 Metric) surface-mount package. It offers an inductance of 19 nH with a ±3% tolerance and a rated current of 850 mA. The component features a DC resistance of 145 mOhm, a self-resonant frequency of 3.5 GHz, and operates within a temperature range of -40°C to 125°C.

Fixed Inductors Feature Summary

• Utilizes a ceramic drum core for stable inductance performance in high-frequency applications.
• Provides high current handling capability suitable for power delivery networks.
• Features an unshielded design to minimize size constraints while maintaining signal integrity.

Fixed Inductors Applications

• RF matching circuits
• DC-DC converter output filtering
• High-speed digital signal line termination

Fixed Inductors Procurement Notes

Verify the suffix EHTS confirms the specific ±3% tolerance variant, as other suffixes like EKTS indicate different tolerances. Confirm RoHS3 compliance status during sourcing. Ensure the supplier provides official datasheets to validate the 145 mOhm DCR and 850 mA rating against counterfeit risks.

Fixed Inductors Selection Notes

Select this component when a low-inductance value near 19 nH is required with tight tolerance control. The 0402 footprint is ideal for dense PCB layouts. Consider the 3.5 GHz self-resonant frequency to ensure operation remains below the resonant point for inductive behavior.

Fixed Inductors Part Context

This part belongs to the 0402HP series from Delta Electronics/Components, designed for high-performance surface-mount applications. The series utilizes wirewound technology on ceramic cores to achieve precise inductance values in miniature packages suitable for modern electronics.

Fixed Inductors Replacement Considerations

The 0402HP-190EGTS serves as a direct substitute, sharing identical electrical parameters but differing in packaging format rather than function. Verify that any alternative maintains the same 0402 footprint and thermal characteristics.
