Procurement Notes
Verify the specific manufacturer designation, as API Delevan components are often listed under API Delevan Inc. Confirm RoHS compliance status through official datasheets, as historical data may vary. Ensure the ordering suffix matches the required tape and reel quantity specifications for production integration.
Selection Notes
Select this component when a shielded surface mount inductor with 4.7 µH nominal value is required. Consider the 175 mA current rating and 3.1 Ohm DC resistance against circuit load requirements. Verify that the 70 MHz self-resonant frequency aligns with the target operating bandwidth for optimal performance.
Part Context
This part belongs to the 105R series of RF inductors manufactured by API Delevan. The series provides shielded, surface-mount solutions designed for high-frequency applications. These components are engineered to support miniaturization trends in modern electronics while maintaining stable electrical characteristics across varying environmental conditions.
Replacement Considerations
Cross-reference with ER1641-472KM for leaded alternatives if surface mount space permits. Verify pin compatibility and thermal profiles before substituting with other manufacturers' 4.7 µH SMD inductors to ensure equivalent Q-factor and saturation current ratings.
