CTMC1812SF-6R8J

Fixed Inductors Overview

The CTMC1812SF-6R8J is a fixed inductor manufactured by Central Technologies, designed for surface-mount applications. It features an unshielded drum core construction with wirewound technology. The component has a nominal inductance of 6.8 µH and a maximum DC resistance of 1.2 Ohm. It supports a current rating of 285 mA and utilizes the standard 1812 (4532 Metric) package dimensions.

Fixed Inductors Feature Summary

• Unshielded drum core design for general-purpose signal handling
• Wirewound construction utilizing ferrite core material
• Surface-mount compatibility within the 1812 footprint

Fixed Inductors Applications

• Television sets
• Video cassette recorders
• Disk drives
• Computer peripherals
• Telecommunication equipment

Fixed Inductors Procurement Notes

Verify the specific suffix 'J' indicates the required tolerance level against project specifications. Confirm that the unshielded configuration aligns with electromagnetic interference requirements for the target circuit board layout. Ensure the 1812 package size fits the designated PCB silkscreen and copper pad definitions prior to finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when a 6.8 µH inductance value is required in a compact surface-mount form factor. Consider the 285 mA current rating to ensure it meets the operational load without saturation. The unshielded nature may necessitate careful placement relative to sensitive traces compared to shielded alternatives.

Fixed Inductors Part Context

This part belongs to the CTMC1812 series of fixed inductors from Central Technologies. It shares the 1812 physical footprint with other variants in the line but differs in inductance values and current ratings. The SF designation typically denotes specific core or winding characteristics within this product family.

Fixed Inductors Replacement Considerations

Direct substitutes include the CTC4F-6R8J, though it uses an axial leaded package rather than surface mount. For equivalent surface-mount performance, verify other 1812 ferrite core wirewound inductors with matching 6.8 µH values and comparable current ratings.
