• High-frequency signal processing

Procurement Notes

Verify the specific manufacturer designation, as API Delevan assets may be managed by other entities. Confirm that the component meets all required environmental standards for the target application. Ensure the ordering suffix matches the desired packaging configuration. Cross-reference the datasheet to validate electrical parameters against system requirements before finalizing procurement.

Selection Notes

Select this component when an unshielded inductor is required for RF applications. The 8.2 µH value and 195 mA current rating suit moderate power levels. Consider the 2.5 Ω DC resistance for voltage drop calculations. The 20 MHz self-resonant frequency defines the upper operational limit. Verify compatibility with the PCB footprint dimensions.

Part Context

This part belongs to the Delevan fixed inductor family, specifically designed for surface-mount integration. It serves as a passive component for managing signal integrity in electronic systems. The product line emphasizes reliability in radio frequency environments. It is distinct from shielded or common-mode variants within the broader catalog.
