10M393J

Overview

The Gowanda Electronics 10M393J is a fixed wirewound inductor from the 10M series, featuring an unshielded ferrite core and axial through-hole mounting. It offers an inductance of 390 µH with a ±5% tolerance. The component supports a maximum rated current of 40 mA and a saturation current of 189 mA, while maintaining a maximum DC resistance of 35 ohms. Designed for operation between -55°C and 125°C, it provides reliable performance for RF coil applications.

Feature Summary

• Unshielded wirewound construction utilizing a ferrite core material
• Axial lead configuration suitable for through-hole installation
• Capable of operating within a wide temperature range of -55°C to 125°C

Applications

• RF coil circuits requiring high reliability
• Aerospace electronic systems
• Defense equipment signal processing

Procurement Notes

Verify that the specific order matches the 10M393J designation rather than similar variants like 10M393JM or LF versions, as suffixes may indicate different packaging or compliance statuses. Confirm the required tolerance level and current ratings align with the circuit design before finalizing procurement actions.

Selection Notes

Select this component when an unshielded axial inductor is necessary to prevent magnetic interference with adjacent sensitive components. Ensure the circuit current does not exceed the 40 mA rated limit to maintain stable inductance values and avoid premature saturation effects during normal operation.
