CTML0603F-220K

Fixed Inductors Overview

The CTML0603F-220K is a shielded multilayer chip inductor manufactured by Central Technologies, designed for surface-mount applications. It features a ferrite core construction within a compact 0603 (1608 metric) package measuring 1.6 x 0.8 x 0.8 mm. The component provides an inductance of 22 µH with a tolerance of ±10%. Key electrical specifications include a maximum DC resistance of 2.1 Ohms and a rated current of 1 mA. The unit operates reliably within a temperature range of -55°C to +125°C.

Fixed Inductors Feature Summary

• Shielded multilayer ferrite construction minimizes electromagnetic interference
• Compact 0603 surface-mount footprint suitable for space-constrained designs
• Wide operating temperature range ensures reliability in harsh environments

Fixed Inductors Applications

• RF filtering circuits
• Power supply output chokes
• Signal processing filters

Fixed Inductors Procurement Notes

Verify the specific suffix 'K' corresponds to the required ±10% tolerance during procurement. Confirm that the 1 mA current rating aligns with the application's peak load requirements. Ensure the 2.1 Ohm DC resistance does not cause excessive voltage drop in the target circuit design before finalizing orders.

Fixed Inductors Selection Notes

Select this component when a 22 µH inductance value is required in a small form factor. Consider the low 1 mA current rating carefully; it is suitable for signal-level or low-power applications rather than high-current power stages. Compare the 2.1 Ohm DCR against circuit loss budgets to ensure efficiency targets are met without compromising performance.

Fixed Inductors Part Context

This part belongs to the CTML0603F series of fixed inductors from Central Technologies. The series utilizes multilayer ceramic technology to provide stable inductance values in standard imperial sizes. The 0603 size offers a balance between component density and electrical performance for consumer electronics and portable devices.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 22 µH inductance, 0603 package dimensions, and similar current ratings. Verify that alternative manufacturers offer comparable shielding characteristics to prevent noise coupling issues in sensitive RF or analog sections of the design.
