0402HM-7N0EDTS

Fixed Inductors Overview

The Delta Electronics/Components 0402HM-7N0EDTS is a fixed wirewound inductor featuring an unshielded drum core design. It offers an inductance of 7 nH with a tolerance of ±0.5nH, tested at 100 MHz. The component supports a rated current of 570 mA and exhibits a DC resistance of 130 mΩ. Key electrical characteristics include a Q value of 25 at 250 MHz and a self-resonant frequency of 6 GHz. Housed in a compact 0402 (1005 Metric) surface-mount package measuring 1.15mm x 0.70mm x 0.60mm, it operates within a temperature range of -55°C to 125°C.

Fixed Inductors Feature Summary

• Unshielded drum core construction for minimal magnetic interference
• High self-resonant frequency capability up to 6 GHz
• Ceramic core material ensuring thermal stability

Fixed Inductors Applications

• RF circuit impedance matching networks
• High-frequency signal filtering applications
• DC-DC converter input/output filtering

Fixed Inductors Procurement Notes

Verify the specific suffix 'EDTS' against official datasheets to confirm tolerance and packaging specifications. Ensure compatibility with RoHS3 compliance requirements for your assembly process. Confirm that the 0402 footprint dimensions align with your PCB layout constraints before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when low inductance values are required for high-frequency operation. The unshielded design necessitates careful placement to avoid coupling with nearby traces. Verify that the 570 mA current rating meets the peak load requirements of the target circuit without causing saturation or excessive heating.

Fixed Inductors Part Context

This part belongs to the 0402HM series of fixed inductors from Delta Electronics/Components. The series utilizes ceramic drum cores optimized for high-frequency performance. Similar parts in the series vary by inductance value and tolerance, such as the 0402HM-7N0ECTS which shares similar electrical parameters but differs in tolerance specification.

Fixed Inductors Replacement Considerations

The 0402HM-7N0ECTS is a verified substitute within the same series, offering identical electrical performance but with a tighter tolerance of ±0.2nH compared to the ±0.5nH of the EDTS variant. Both share the same package and current ratings.
