Procurement Notes

Verify the specific ordering suffix and package configuration against the manufacturer's current documentation before purchase. Confirm that the requested quantity aligns with the supplier's available stock levels and minimum order requirements. Ensure compatibility with automated surface mount assembly processes by checking the reel or cut tape specifications provided in the official datasheet.

Selection Notes

Select this component when a low inductance value near 1.8nH is required within a standard 0805 footprint. Consider the high self-resonant frequency of 6GHz for applications demanding minimal parasitic effects at higher frequencies. Evaluate the DC resistance limit of 100 mOhm against the circuit's current handling needs to ensure efficient operation without excessive power loss.

Part Context

This part belongs to the LL2012-F Series of fixed inductors manufactured by Toko America Inc. The series represents a line of miniature multilayer ceramic chip inductors designed for modern electronics requiring small form factors. These components are engineered to provide reliable inductance values while maintaining high Q factors and self-resonant frequencies typical of advanced ceramic technologies.

Replacement Considerations

Consult official substitution lists for compatible parts within the LL2012 family, such as the LL2012-FHL Series, which shares similar footprint characteristics but may differ in electrical parameters. Verify that any alternative component matches the 0805 package dimensions and meets the required 1.8nH inductance specification.
