15M103K

Overview

The 15M103K is a fixed inductor manufactured by Gowanda Electronics, classified as a molded unshielded RF coil with an axial leaded package. It features a nominal inductance of 100 µH and a tolerance of 10%. The component has a maximum DC resistance of 4.5 Ohms and supports a current rating of 133 mA. Designed for through-hole mounting, it utilizes an iron-ferrite core within a cylindrical construction.

Feature Summary

• Unshielded molded construction suitable for radio frequency applications
• Axial leaded configuration for standard through-hole circuit board integration
• Iron-ferrite core material providing general-purpose inductive characteristics

Applications

• Radio frequency signal processing circuits
• General purpose electronic filtering applications
• Through-hole mounted analog signal conditioning systems

Procurement Notes

Verify RoHS compliance status directly with the manufacturer or authorized distributors, as regulatory declarations may vary by production batch. Confirm terminal lead composition regarding lead content requirements before finalizing procurement specifications to ensure alignment with project environmental standards.

Selection Notes

Select this component when an unshielded axial inductor with 100 µH nominal value is required. Ensure the 133 mA current rating and 4.5 Ohm DC resistance meet the specific circuit load requirements. Verify that the lack of shielding does not interfere with adjacent sensitive components in the layout design.

Part Context

This part belongs to the Gowanda Electronics 15M series of molded unshielded RF coils. The series offers various inductance values in an axial package format. The 15M103K specifically denotes the 100 µH variant within this standardized line of general-purpose wirewound inductors designed for robust through-hole implementation.

Replacement Considerations

Compatible substitutes include the 15M103MLF from the same manufacturer family. Other Gowanda models such as 8M103K share similar electrical parameters but differ in physical dimensions and core materials; verify mechanical fit and thermal characteristics before substitution.
