Fixed Inductors Procurement Notes

Verify the specific suffix 'F' against official Central Technologies documentation to confirm if it denotes a specific tape-and-reel packaging variant or a distinct manufacturing lot code, as standard datasheets may list only the base series prefix. Ensure compliance requirements such as RoHS status are confirmed via the manufacturer's current product declaration, as lead-free status can vary by production batch.

Fixed Inductors Selection Notes

Select this component when a precise 820 nH inductance with tight ±5% tolerance is required for high-frequency signal paths. The ceramic core material offers superior predictability compared to air cores, while the SMD package facilitates compact PCB layouts. Consider the 1.82 Ω DC resistance and 420 MHz self-resonant frequency limits when designing for power handling and bandwidth constraints.
