- General purpose RF signal processing
Procurement Notes
Verify the specific suffix (e.g., R) against official API Delevan documentation to confirm exact electrical tolerances and packaging configurations. Ensure the procurement channel provides valid RoHS compliance data, as availability varies by distributor. Cross-reference the datasheet parameters for self-resonant frequency and current ratings before integration into final designs.
Selection Notes
Select this component when a high-inductance value of 160 µH is required in a compact axial form factor. Consider the 126 mA current limit and 6.4 Ohm DC resistance for power budget calculations. The unshielded design requires careful layout consideration to minimize electromagnetic interference with adjacent circuitry compared to shielded alternatives.
Part Context
This part belongs to the 1537 series of RF inductors manufactured by API Delevan. The series offers various inductance values with different tolerance options. The 'R' suffix typically denotes specific manufacturing or tolerance variations within the product line. These components are standard passive elements used in electronic assemblies requiring precise inductive properties.
Replacement Considerations
Direct substitutes must match the 160 µH inductance, 126 mA current rating, and axial package dimensions. Verify that alternative parts maintain similar Q factors and self-resonant frequencies to ensure circuit stability. Check for equivalent DC resistance values to prevent thermal issues.
