10M392K

Overview

The Gowanda Electronics 10M392K is a fixed, unshielded wirewound inductor designed for radio frequency applications. It features a powdered iron core and an axial lead configuration housed in a tubular package. The component exhibits an inductance of 39 µH with a tolerance of ±10%. It supports a maximum rated current of 125 mA and has a maximum DC resistance of 3.6 ohms. The self-resonant frequency is specified at 22 MHz, and the quality factor is 45.

Feature Summary

• Utilizes a powdered iron core to support high-frequency RF performance
• Features an unshielded wirewound construction for general-purpose use
• Provides axial lead mounting for through-hole integration

Applications

• Radio frequency circuit filtering
• General purpose inductive components
• Aerospace and defense electronic systems

Procurement Notes

Verify that the specific order matches the 10M392K part number exactly, as Gowanda offers various series with differing electrical characteristics. Confirm that the axial lead style and tubular package dimensions align with the target PCB layout requirements. Ensure the 125 mA current rating meets the operational load conditions without saturation or excessive thermal rise.

Selection Notes

Select this component when a 39 µH inductance value is required for RF applications with moderate current handling needs. The unshielded design may necessitate careful placement to avoid magnetic interference with nearby sensitive traces. Consider the 3.6 ohm DC resistance impact on voltage drop within the circuit path during initial design validation.

Part Context

This inductor belongs to Gowanda's standard RF coil lineup, which caters to demanding sectors such as aerospace, defense, and medical equipment. The manufacturer provides both RoHS-compliant and traditional leaded options to suit different regulatory and environmental constraints across global supply chains.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Cross-referencing requires matching the 39 µH inductance, 125 mA current rating, 3.6 ohm DCR, and axial form factor precisely.
