Procurement Notes
Verify the exact electrical parameters against the official Gowanda Electronics datasheet prior to procurement. Confirm that the 170 mA current rating and 2.75 ohm DC resistance align with your system's thermal and power constraints. Ensure the unshielded nature of the component does not interfere with nearby sensitive circuitry due to potential magnetic field emission.
Selection Notes
Select this component when an unshielded axial inductor is required for frequencies up to its self-resonant limit. The 47 µH value suits moderate inductance needs in RF stages. Consider the physical size and lead spacing if space is constrained. Verify compatibility with the operating temperature range specified in the manufacturer documentation before finalizing the design.
Part Context
This part belongs to the Gowanda Electronics line of molded RF coils. These components are engineered for demanding environments where standard inductors may fail. The axial lead style allows for easy integration into traditional through-hole assembly processes. The product series emphasizes durability and consistent performance in radio frequency applications.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided data. Cross-referencing requires matching the 47 µH inductance, 170 mA current rating, and axial package dimensions. Consult Gowanda Electronics directly for equivalent or upgraded alternatives within their portfolio.
