CTDT1608CF-683

Fixed Inductors Overview

The CTDT1608CF-683 is a shielded power inductor manufactured by Central Technologies. It features a fixed inductance of 68 µH with a tolerance of ±20%. The component has a maximum DC resistance (DCR) of 0.575 Ω and a saturation current rating of 30 mA. The test frequency for inductance measurement is specified at 100 kHz. This surface-mount device is designed for general-purpose power applications.

Fixed Inductors Feature Summary

• Magnetic shielding structure to reduce electromagnetic interference
• Ferrite core construction for stable performance
• Surface-mount package design for automated assembly

Fixed Inductors Applications

• General purpose power inductor circuits
• DC-DC converter input/output filtering
• Power supply ripple suppression

Fixed Inductors Procurement Notes

Verify the specific suffix 'CF' against the manufacturer's latest datasheet to confirm RoHS compliance status and lead-free plating specifications. Ensure the ordering code matches the required inductance value of 68 µH and the current ratings of 30 mA saturation and 290 mA RMS, as these parameters are critical for circuit reliability and thermal management.

Fixed Inductors Selection Notes

Select this component when a compact, shielded inductor is required for low-current power stages. The 68 µH value suits applications needing moderate energy storage with tight space constraints. Consider the 30 mA saturation limit carefully; if higher current handling is needed, a different part from the series with lower inductance or larger physical dimensions should be evaluated to prevent core saturation.

Fixed Inductors Part Context

This part belongs to the CTDT1608CF series of shielded power inductors from Central Technologies. The series offers various inductance values ranging from 10 µH to 100 µH, all sharing similar physical footprints and shielding characteristics. These components are intended for use in portable electronics and compact power modules where size and EMI reduction are prioritized.

Fixed Inductors Replacement Considerations

The DT1608C-683MLTC from Coilcraft is a documented alternative within the same form factor family. Verify that the replacement's DCR and current ratings meet or exceed the original requirements before substitution.
