The package dimensions are 6.35 mm in length and 2.413 mm in diameter, with leads measuring 0.5105 mm in diameter.

Feature Summary

• Molded unshielded construction for reliable performance in various electronic environments
• Axial lead configuration suitable for through-hole mounting
• Iron-ferrite core material optimized for RF coil applications

Applications

• RF choke circuits
• General purpose inductive filtering
• Aerospace and defense electronic systems

Procurement Notes

Verify the specific ordering suffix to confirm compliance status, as standard variants may differ from RoHS-compliant versions. Confirm that the axial lead style matches the target PCB layout requirements. Ensure the operating temperature range aligns with the system's environmental specifications. Check for any ITAR restrictions if the application involves controlled defense items. Validate the DC resistance value against circuit design constraints.

Selection Notes

Select this component when a 20 µH inductance with tight 5% tolerance is required for RF applications. The axial form factor is ideal for through-hole assembly processes. Consider the 3.2 Ω DC resistance impact on circuit efficiency. The molded case provides mechanical stability compared to bare wirewound designs. Evaluate the 415 mA current limit against peak load conditions.

Part Context

This part belongs to the 10M series of standard RF inductors manufactured by Gowanda Electronics. The series includes various inductance values ranging from 0.1 µH to higher capacities. These components are widely used in aerospace, defense, and medical sectors due to their reliability. The manufacturer offers both leaded and surface mount options within this product family.

Replacement Considerations

Direct substitutes must match the 20 µH inductance, 5% tolerance, and axial package dimensions. Verify core material compatibility to ensure similar RF performance characteristics. Cross-reference DC resistance and current ratings to prevent thermal issues. Consult Gowanda Electronics for updated RoHS-compliant equivalents if lead-free assembly is mandatory.
