0402HM-2N7EKTS

Fixed Inductors Overview

The 0402HM-2N7EKTS is a fixed surface-mount inductor from Delta Electronics/Components, designed for high-frequency applications. It features an unshielded drum core wirewound construction with a ceramic magnetic core. The component provides an inductance of 2.7 nH with a tolerance of ±0.1nH and operates at a test frequency of 100 MHz. It supports a rated current of 850 mA and exhibits a DC resistance of 50 mOhm. The self-resonant frequency reaches 15 GHz, with a Q value of 20 measured at 250 MHz. Housed in a compact 0402 (1005 Metric) package measuring 1.15mm x 0.70mm x 0.60mm, it functions within a temperature range of -55°C to 125°C.

Fixed Inductors Procurement Notes

Verify the specific suffix 'K' against official Delta documentation to confirm the exact tolerance specification, as variations exist within the 0402HM series. Ensure the ordering part number matches the required ±0.1nH tolerance rather than other available variants like ±0.5nH or ±10%. Confirm RoHS3 compliance status directly with the manufacturer prior to final procurement decisions.

Fixed Inductors Selection Notes

Select this component when ultra-low inductance values are required for RF circuits. The unshielded construction may necessitate careful PCB layout to minimize electromagnetic interference coupling with adjacent traces. Evaluate the 850 mA current rating against peak load requirements to prevent saturation. Consider the 15 GHz self-resonant frequency limit to ensure stable operation within the target frequency band.
