Procurement Notes
Verify the specific part number against official Gowanda Electronics documentation to confirm electrical parameters such as inductance tolerance and current rating. Ensure compliance with project requirements regarding leaded components and RoHS status, as this model may not meet all environmental directives. Cross-reference datasheets for thermal limits and physical dimensions before finalizing procurement.
Selection Notes
Select the 15M182K when a fixed 18 µH inductance is required for RF signal processing. Consider its 185 mA current rating and 2.25 Ω DC resistance for power handling constraints. The unshielded design necessitates careful PCB layout to minimize electromagnetic interference with adjacent components in dense assemblies.
Part Context
This component belongs to Gowanda Electronics' line of high-performance fixed inductors designed for specialized industries. The manufacturer specializes in custom magnetics and RF coils for sectors where reliability is critical. This specific model represents a standard value within their broader portfolio of axial wirewound inductors.
Replacement Considerations
Consult Gowanda Electronics for direct substitutes or updated series equivalents. Verify that any alternative maintains the 18 µH inductance, 185 mA current rating, and compatible package dimensions to ensure seamless integration without redesigning the host circuit board.
