0402HM-8N7EGTS

Fixed Inductors Overview

The Delta Electronics/Components 0402HM-8N7EGTS is an unshielded, drum core, wirewound fixed inductor housed in a 0402 (1005 Metric) surface-mount package. It features a nominal inductance of 8.7 nH with a tolerance of ±0.2 nH and a DC resistance of 140 mΩ. The component supports a rated current of 540 mA and achieves a Q value of 25 at 250 MHz. Its self-resonant frequency reaches 3.2 GHz, measured at a test frequency of 100 MHz. Operating temperatures range from -55°C to 125°C, utilizing a ceramic core material.

Fixed Inductors Feature Summary

• Unshielded drum core wirewound construction for high-frequency stability
• Compact 0402 surface-mount footprint for dense PCB layouts
• High self-resonant frequency capability suitable for RF applications

Fixed Inductors Applications

• RF matching networks
• DC-DC converter input/output filtering
• High-speed digital signal line termination

Fixed Inductors Procurement Notes

Verify the specific suffix EGTS against official Delta Electronics documentation to confirm exact tolerance and packaging specifications. Ensure compatibility with RoHS3 standards and check moisture sensitivity level requirements during storage and handling. Confirm lead times as these components are often manufactured to order rather than held in general stock.

Fixed Inductors Selection Notes

Select this component when ultra-low inductance values near 9 nH are required in minimal space. Consider the 540 mA current rating and 140 mΩ DCR for power efficiency constraints. Evaluate the 3.2 GHz self-resonant limit to ensure operation remains below the resonant point for inductive behavior in target circuits.

Fixed Inductors Part Context

This part belongs to the 0402HM series of fixed inductors from Delta Electronics/Components. The series utilizes ceramic cores and wirewound techniques to provide consistent performance in small form factors. Similar parts in the series include variants with different inductance values such as 8.2 nH or 9.1 nH, sharing identical physical dimensions and mounting characteristics.

Fixed Inductors Replacement Considerations

Cross-reference with other 0402 unshielded wirewound inductors offering 8.7 nH ±0.2 nH. Verify that substitute components match the 540 mA current rating and 140 mΩ DCR to maintain circuit performance. Check for equivalent self-resonant frequencies to prevent impedance mismatches.
