CTDR1F-270K

Fixed Inductors Overview

The CTDR1F-270K is a fixed radial inductor manufactured by Central Technologies, featuring a drum core design with wirewound construction. It provides a nominal inductance of 27 µH with a tolerance of ±10%. The component has a maximum DC resistance of 30 mΩ and operates within a temperature range of -55°C to +125°C. It is unshielded, RoHS compliant, and lead-free, designed for vertical mounting on printed circuit boards.

Fixed Inductors Feature Summary

• Unshielded drum core construction for cost-effective general-purpose applications
• Vertical radial leaded package suitable for through-hole mounting
• RoHS compliant and lead-free manufacturing process

Fixed Inductors Applications

• General purpose filtering circuits
• Power supply input/output stages
• Signal conditioning networks

Fixed Inductors Procurement Notes

Verify the part number suffix 'F' indicates the specific drum core variant rather than generic axial types. Confirm RoHS compliance status matches current regulatory requirements. Ensure the vendor provides original manufacturer documentation to validate the 30 mΩ DC resistance specification. Check that the supplier guarantees authenticity against counterfeit components.

Fixed Inductors Selection Notes

Select this component when an unshielded radial inductor is required for space-constrained vertical layouts. Consider the 27 µH value and 30 mΩ resistance for low-loss applications. Verify thermal performance meets the -55°C to +125°C operating range. Compare against shielded alternatives if electromagnetic interference mitigation is necessary.

Fixed Inductors Part Context

This part belongs to the CTDR1F series of fixed inductors from Central Technologies. The series includes various inductance values ranging from microhenries to millihenries. All variants share the same radial drum core form factor and wirewound technology, differing primarily in inductance and DC resistance specifications.

Fixed Inductors Replacement Considerations

Direct substitutes include other 27 µH radial drum core inductors with similar DC resistance and current ratings. Verify pin compatibility and physical dimensions before substitution. Cross-reference with CTDR1-270K if shielding differences are acceptable.
