10M222K

Overview

The 10M222K is a fixed wirewound inductor manufactured by Gowanda Electronics. It features an inductance of 22 µH with a tolerance of ±10%. The component is designed for axial lead mounting and operates at a frequency of 2.5 MHz. It has a maximum DC current rating of 140 mA and a maximum direct current resistance (DCR) of 3.3 Ohms. The unit is unshielded and utilizes a molded construction.

Feature Summary

• Axial lead configuration for through-hole PCB integration
• Unshielded wirewound design suitable for non-interference applications
• Molded construction for mechanical stability

Applications

• High-frequency RF circuit filtering
• Broadband power transformer coupling
• General-purpose signal processing stages

Procurement Notes

Verify the specific suffix designation when ordering, as variations such as 'J' or 'TR' may indicate different tolerances or packaging formats. Confirm that the unshielded nature aligns with the electromagnetic interference requirements of the target application. Ensure the axial lead pitch matches the printed circuit board layout constraints before finalizing procurement.

Selection Notes

Select this component when a 22 µH inductance value is required for high-frequency operations up to 2.5 MHz. The 140 mA current rating dictates suitability for low-power signal paths rather than high-current power delivery. The unshielded construction requires careful placement to avoid magnetic coupling with adjacent sensitive components.

Part Context

This part belongs to Gowanda's line of fixed inductors, which includes standard and custom designs for aerospace, defense, and medical sectors. The manufacturer provides RoHS-compliant options and maintains ITAR registration for critical government applications. The product range encompasses various shielding and mounting configurations to meet diverse engineering specifications.

Replacement Considerations

The 10M222J serves as a potential substitute if a different tolerance level is acceptable. Verify that any replacement maintains the same axial lead dimensions and 22 µH inductance value to ensure circuit compatibility without redesign.
