CTML1206F-3R3K

Fixed Inductors Overview

The CTML1206F-3R3K is a fixed surface-mount inductor from Central Technologies, designed for general-purpose applications. It features a ferrite core and multilayer chip construction within a 1206 (3216 metric) package. The component provides a nominal inductance of 3.3 µH with a maximum DC resistance of 700 mΩ and a rated current of 50 mA. It operates reliably within a temperature range of -55 °C to +125 °C.

Fixed Inductors Feature Summary

• Shielded multilayer chip design utilizing a ferrite core
• Surface mount configuration in a standard 1206 footprint
• RoHS compliant and lead-free manufacturing

Fixed Inductors Applications

• RF circuit filtering
• General purpose signal processing
• Power supply output chokes

Fixed Inductors Procurement Notes

Verify the specific tolerance code required for the order, as specifications may vary based on suffix codes. Confirm that the 50 mA rated current and 700 mΩ DC resistance align with the target circuit requirements. Ensure the 1206 package dimensions fit the designated PCB layout constraints before finalizing procurement.

Fixed Inductors Selection Notes

Select this component when a shielded 3.3 µH inductor is needed in a compact 1206 package. The low profile and ferrite core make it suitable for space-constrained designs requiring RF performance. Consider the 50 mA current limit to ensure adequate headroom for the application's peak load conditions.

Fixed Inductors Part Context

This part belongs to the CTML1206F series of multi-layer chip inductors manufactured by Central Technologies. The series offers a wide range of inductance values, typically spanning from 0.047 µH to 33 µH, all sharing the same 1206 surface-mount form factor and ferrite core technology for consistent performance characteristics.

Fixed Inductors Replacement Considerations

Direct substitutes include other 3.3 µH shielded inductors in the 1206 package with comparable current ratings. Verify that alternative parts maintain similar DC resistance and self-resonant frequency specifications to ensure circuit compatibility without redesign.
