0402HS-390EKTS

Fixed Inductors Overview

The Delta Electronics/Components 0402HS-390EKTS is a fixed surface-mount inductor designed for compact electronic circuits. It features an unshielded drum core wirewound construction with a ceramic magnetic core, housed in a standard 0402 (1005 Metric) package measuring 1.15mm x 0.70mm x 0.60mm maximum height. The component provides an inductance of 39 nH with a tolerance of ±10%. It supports a rated current of 200 mA and exhibits a DC resistance of 550 mOhm. The self-resonant frequency reaches 2.6 GHz, tested at 250 MHz, ensuring stable performance across high-frequency applications within an operating temperature range of -40°C to 125°C.

Fixed Inductors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact electrical tolerances and packaging configurations. Ensure that the selected variant matches the required current rating and impedance specifications for the target circuit design. Cross-reference the RoHS compliance status and moisture sensitivity level requirements with the assembly process standards before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when space constraints require a 0402 package size combined with low inductance values suitable for high-frequency operation. The unshielded construction is appropriate for applications where external magnetic shielding is managed by the system layout or where minimal parasitic capacitance is critical. Evaluate the 200 mA current limit against peak load conditions to prevent saturation.

Fixed Inductors Part Context

This part belongs to the 0402HS series of fixed inductors from Delta Electronics/Components. The series utilizes ceramic cores for stability and offers various inductance options within the small 0402 form factor. It is positioned as a passive magnetic component for consumer electronics, automotive systems, and cloud computing equipment requiring reliable high-frequency performance.

Fixed Inductors Replacement Considerations

Direct substitutes include the 0402HP-390EHTS, which shares the same 39 nH inductance but differs in current rating (450 mA vs 200 mA) and DC resistance (430 mOhm vs 550 mOhm). Verify that the alternative component's physical dimensions and thermal characteristics fit the existing board layout without modification.
