Fixed Inductors Procurement Notes

Verify the specific ordering suffix when purchasing to ensure correct tolerance and packaging configuration. Confirm that the required operating temperature range aligns with the specified -55 °C to 125 °C limits. Ensure the target circuit current does not exceed the 15 mA maximum rating to prevent performance degradation or thermal issues during operation.

Fixed Inductors Selection Notes

Select this component for designs requiring a 12 µH inductance in a compact 0805 footprint. Consider the 1.2 Ω DC resistance and 15 mA current limit when evaluating power loss and saturation characteristics. The 22 MHz SRF defines the upper frequency limit for effective inductive behavior in high-speed signal paths.

Fixed Inductors Part Context

This part belongs to the CTML0805F series of multilayer chip inductors produced by Central Technologies. The series offers various inductance values ranging from low nanohenry to higher microhenry levels within the same 0805 form factor. These components are engineered for space-constrained electronic assemblies requiring reliable passive filtering.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 12 µH value, 0805 package, and similar electrical parameters such as DCR and SRF. Verify that alternative manufacturers offer compatible tolerance ratings and temperature coefficients for equivalent circuit performance.
