10M391J

Overview

The Gowanda Electronics 10M391J is a fixed, unshielded wirewound RF coil designed for axial lead mounting. It features an inductance of 3.9 µH with a tolerance of ±5%. The component has a maximum DC current rating of 250 mA and a maximum DC resistance of 1 Ohm. It is constructed using molded encapsulation to ensure mechanical stability and environmental protection.

Feature Summary

• Unshielded wirewound construction suitable for radio frequency applications
• Axial lead configuration for through-hole installation
• Molded encapsulation for physical durability

Applications

• Radio frequency circuits
• General purpose filtering
• Impedance matching networks

Procurement Notes

Verify the specific suffix requirements for lead-free compliance when ordering, as standard versions may differ from RoHS-compliant variants. Confirm axial lead dimensions against the official datasheet to ensure compatibility with existing PCB footprints. Check for any recent product change notices regarding material composition or manufacturing location updates.

Selection Notes

Select this component for applications requiring moderate inductance values in compact axial packages. Ensure the operating current remains below the 250 mA limit to prevent saturation or thermal issues. Consider the lack of shielding when designing layouts to minimize electromagnetic interference coupling with nearby traces.

Part Context

This part belongs to Gowanda's line of molded unshielded RF coils. These components are engineered for reliability in demanding environments. The manufacturer specializes in custom and standard magnetic devices for aerospace, defense, and industrial sectors, offering both standard and military-grade options.

Replacement Considerations

The 10M391JLF serves as the lead-free compliant alternative within the same series. Verify that the electrical parameters and physical dimensions remain identical before substitution to maintain circuit performance and board fit.
