0603CS-3N9EJTS

Fixed Inductors Overview

The Delta Electronics/Components 0603CS-3N9EJTS is a fixed surface-mount power inductor with an unshielded drum core and wirewound construction. It features a ceramic chip inductor design housed in a 0603 (1608 Metric) package measuring 1.6 mm in length, 0.8 mm in width, and 1.02 mm in height. The component provides an inductance of 3.9 nH with a tolerance of ±5%. It supports a maximum DC current of 700 mA and exhibits a maximum DC resistance of 80 mΩ. Electrical performance includes a Q factor of 22 at 250 MHz and a self-resonant frequency of 6 GHz.

Fixed Inductors Feature Summary

• Unshielded drum core wirewound construction for high-frequency signal integrity
• Ceramic chip inductor material ensuring stable thermal performance
• Compact 0603 surface-mount footprint optimized for dense PCB layouts

Fixed Inductors Applications

• RF circuit impedance matching networks
• High-speed digital signal line filtering
• DC-DC converter input/output filtering
• Power delivery network decoupling

Fixed Inductors Procurement Notes

Verify the manufacturer part number against official Delta Electronics/Components documentation to confirm specifications. Ensure compatibility with RoHS3 compliance requirements if applicable. Check for any regional distribution restrictions or shipping limitations before ordering. Confirm that the unshielded design aligns with electromagnetic interference constraints in the target application environment.

Fixed Inductors Selection Notes

Select this component when a low-inductance value near 3.9 nH is required for high-frequency applications. Consider the 700 mA current rating and 80 mΩ DC resistance for power efficiency needs. The unshielded structure may require careful layout planning to minimize crosstalk. Evaluate the 6 GHz self-resonant frequency to ensure operation remains below the resonance point for intended use cases.

Fixed Inductors Part Context

This part belongs to the 0603CS series of fixed inductors from Delta Electronics/Components. The series utilizes ceramic core materials and wirewound technology to achieve consistent electrical characteristics in small form factors. Similar parts in the series vary primarily in inductance values while maintaining comparable package dimensions and mounting styles.

Fixed Inductors Replacement Considerations

Cross-reference with other 0603CS series variants such as 0603CS-3N3EJTS for different inductance requirements. Verify that substitute components match the 0603 package dimensions and pin configuration. Ensure replacement parts maintain equivalent current ratings and DC resistance values to preserve circuit performance.
