0402HM-5N8ECTS

Fixed Inductors Overview

The 0402HM-5N8ECTS 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 5.8 nH with a tolerance of ±0.2nH and operates at a test frequency of 100 MHz. It has a DC resistance (DCR) of 120 mOhm and supports a rated current of 700 mA. The self-resonant frequency reaches 8 GHz, with a Q factor of 25 at 250 MHz. Packaged in a 0402 (1005 Metric) footprint measuring 1.15mm x 0.70mm x 0.60mm max height, it functions within a temperature range of -55°C to 125°C.

Fixed Inductors Feature Summary

• Unshielded drum core wirewound design utilizing ceramic magnetic material
• High self-resonant frequency capability up to 8 GHz
• Compact 0402 surface mount package suitable for dense PCB layouts

Fixed Inductors Applications

• RF circuit impedance matching networks
• High-speed digital signal filtering
• Power supply output filtering in compact modules

Fixed Inductors Procurement Notes

Verify the specific suffix ECTS corresponds to the required tape and reel packaging configuration before ordering. Confirm that the 120 mOhm DCR and 700 mA current rating align with the target circuit's power budget. Ensure the 0402 footprint dimensions match the board layout constraints. Check RoHS3 compliance status if environmental regulations apply to the final assembly. Validate the operating temperature range against the intended thermal environment.

Fixed Inductors Selection Notes

Select this component when ultra-low inductance values near 6 nH are required for RF or high-speed data lines. The unshielded nature necessitates careful placement to minimize electromagnetic interference with nearby traces. Compare the 120 mOhm DCR against alternative inductors to ensure acceptable voltage drop and power loss. Consider the 8 GHz self-resonant frequency limit to avoid parasitic effects in the target application bandwidth.

Fixed Inductors Part Context

This part belongs to the 0402HM series of fixed inductors manufactured by Delta Electronics/Components. The series offers various low-nanohenry values optimized for high-frequency performance. The 0402 form factor allows for miniaturization in modern electronic devices. Similar parts in the series include different inductance values such as 5.1 nH or 6.8 nH, sharing the same physical package and general electrical characteristics.

Fixed Inductors Replacement Considerations

Direct substitutes may include other 0402 unshielded wirewound inductors with 5.8 nH nominal value. Verify equivalent DCR, current rating, and self-resonant frequency. Cross-reference with manufacturers like Murata or TDK for compatible 0402 HM-series alternatives. Ensure pin compatibility and soldering profile alignment during replacement.
