Overview
The Gowanda Electronics 10M203K is a fixed wirewound inductor with an inductance of 200 µH and a tolerance of ±10%. It features an unshielded design using a phenolic core material, rated for a maximum current of 815 mA. The component has a maximum DC resistance of 0.14 ohms and operates within a temperature range of -55°C to 105°C. It utilizes an axial lead package for through-hole mounting.
Feature Summary
- Unshielded wirewound construction for RF applications
- Phenolic core material providing stable magnetic properties
- Axial lead configuration suitable for through-hole installation
Applications
- RF circuit filtering
- Signal conditioning
- General-purpose inductive components
Procurement Notes
Verify the specific suffix codes against official Gowanda documentation to confirm exact electrical tolerances and packaging variations. Ensure that the phenolic core specification aligns with your thermal management requirements, as operating temperatures extend up to 105°C. Cross-reference the DCR value of 0.14 ohms with your circuit's power loss constraints before finalizing procurement.
Selection Notes
Select this component when a 200 µH inductance is required for RF or signal processing tasks. The unshielded nature necessitates careful layout planning to minimize electromagnetic interference with adjacent traces. Verify that the 815 mA current rating exceeds the peak operational current of your application to prevent saturation effects.
Part Context
This part belongs to the Gowanda 10M series of fixed inductors, which are designed for high-performance applications in aerospace, defense, and medical sectors. The series offers various inductance values with consistent axial lead packaging, allowing for standardized integration into custom magnetics designs requiring reliable passive components.
Replacement Considerations
Consult Gowanda Electronics for direct cross-references. Generic replacements must match the 200 µH inductance, 815 mA current rating, and 0.14 ohm DCR. Phenolic core availability may vary among substitutes.
