0402HP-3N9EKTS

Fixed Inductors Overview

The 0402HP-3N9EKTS is a fixed surface-mount inductor from Delta Electronics/Components, featuring a 3.9 nH nominal inductance with ±0.1nH tolerance. It utilizes an unshielded drum core wirewound design on ceramic material, housed in a compact 0402 (1005 Metric) package measuring 1.15mm x 0.70mm x 0.60mm max height. The component supports a current rating of 1.7 A and exhibits a DC resistance of 45 mOhm. It operates within a temperature range of -55°C to 125°C, offers a self-resonant frequency of 9.5 GHz, and complies with RoHS3 standards.

Fixed Inductors Procurement Notes

Verify the specific ordering suffix 'K' against official Delta documentation to confirm tape-and-reel packaging specifications. Ensure that the selected variant matches the required current rating and DCR values for the target application. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm availability status and lead times prior to final procurement decisions.

Fixed Inductors Selection Notes

Select this component when a low-inductance value near 3.9 nH is required for RF or high-speed digital applications. The unshielded design minimizes parasitic capacitance but may require careful layout to manage EMI. Verify that the 1.7 A current rating exceeds the peak operating current of the circuit. Consider the 0402 package size constraints during PCB layout planning to ensure adequate solder paste volume and thermal relief.

Fixed Inductors Part Context

This part belongs to the 0402HP series of fixed inductors from Delta Electronics/Components. The series is characterized by small form factors and high self-resonant frequencies, targeting modern electronics requiring miniaturization. The HP designation typically indicates specific performance characteristics within the broader 0402HM family, distinguishing it from standard variants through optimized electrical parameters for high-frequency use.

Fixed Inductors Replacement Considerations

The 0402HM-3N9EBTS is a related variant within the same product family. However, it features different electrical specifications, including a lower current rating of 750 mA and higher DC resistance of 70 mOhm. Direct substitution requires verification that the reduced current handling and increased resistance are acceptable for the specific circuit requirements.
