15M220M

Overview

The 15M220M is a fixed inductor manufactured by Gowanda Electronics, featuring an unshielded molded construction with axial leads. It provides an inductance of 220 nH and supports a maximum DC current of 1.9 A. The component exhibits a maximum DC resistance of 55 mOhm and operates with a self-resonant frequency of 450 MHz. Designed for RF applications, this wirewound coil combines compact physical dimensions with stable electrical performance suitable for signal conditioning and moderate-power circuits.

Feature Summary

• Unshielded molded construction for minimal electromagnetic interference coupling
• Axial lead configuration facilitating through-hole mounting
• Wirewound design optimized for radio frequency stability

Applications

• RF circuit signal conditioning
• Moderate-power radio frequency systems
• Aerospace electronic assemblies
• Defense communication equipment

Procurement Notes

Verify the specific suffix designation against official Gowanda documentation to confirm exact tolerance and termination specifications. Ensure the procurement channel sources directly from authorized distributors or the manufacturer to guarantee component authenticity and traceability. Cross-reference the part number with the latest datasheet to validate compliance with required environmental and performance standards before integration.

Selection Notes

Select the 15M220M when a low-inductance value near 220 nH is required for high-frequency operation up to 450 MHz. Consider its 1.9 A current rating and 55 mOhm resistance for power handling needs. Evaluate the unshielded nature against potential crosstalk requirements in dense PCB layouts. Confirm that axial packaging aligns with the assembly process and mechanical constraints of the target design.

Part Context

This component belongs to the Gowanda Electronics 15M series of precision fixed inductors. The series specializes in molded, unshielded wirewound coils designed for demanding RF and microwave environments. These components are engineered for aerospace, defense, and medical sectors where reliability and consistent electrical characteristics are critical for system performance.

Replacement Considerations

Consult official Gowanda documentation for verified substitute part numbers. Direct replacements must match the 220 nH inductance, 1.9 A current rating, and axial form factor. Generic equivalents may not replicate the specific self-resonant frequency or molding quality required for certified aerospace or defense applications.
