Fixed Inductors Procurement Notes

Verify the specific tolerance code required for the order, as specifications may vary based on the suffix. Confirm that the operating environment remains within the stated temperature limits of -55 °C to +125 °C. Ensure the PCB layout accommodates the 0603 footprint dimensions accurately. Check for any specific handling requirements related to the surface-mount package type during assembly processes.

Fixed Inductors Selection Notes

Select this component when a compact surface-mount inductor with a 0.18 µH value is required for RF or general-purpose applications. Consider the 0.7 A current rating and 0.4 Ω DC resistance for power handling needs. The ferrite core selection provides appropriate performance characteristics for frequencies up to the self-resonant point. Verify compatibility with automated placement equipment due to the small form factor.

Fixed Inductors Part Context

This part belongs to the CTML0603F series of multilayer chip inductors manufactured by Central Technologies. The series offers various inductance values ranging from low nanohenry to higher microhenry levels within the same 0603 case size. These components are engineered for high-frequency stability and are commonly integrated into consumer electronics and communication devices requiring reliable passive components.

Fixed Inductors Replacement Considerations

Direct substitutes include other 0603 ferrite-core inductors with matching 0.18 µH inductance and similar current ratings. Verify pinout compatibility and physical dimensions before substitution. Cross-reference with manufacturer datasheets to ensure equivalent Q-factor and self-resonant frequency performance.
