CTH6VF-270K

Fixed Inductors Overview

The CTH6VF-270K is an unshielded wirewound axial inductor from Central Technologies, designed for power line applications. It features a nominal inductance of 27 µH with a maximum DC resistance of 220 mΩ and a self-resonant frequency of 8.0 MHz. The component utilizes a varnish coating (indicated by the VF suffix) and supports through-hole mounting. It is RoHS3 compliant and suitable for general-purpose inductive filtering tasks.

Fixed Inductors Feature Summary

• Unshielded wirewound construction for standard inductive performance
• Axial leaded package optimized for through-hole PCB mounting
• Varnish coated finish providing environmental protection

Fixed Inductors Applications

• Power line chokes
• General purpose inductive filtering
• Signal conditioning circuits

Fixed Inductors Procurement Notes

Verify the specific ordering suffix to confirm the coating type; the 'VF' designation indicates a varnish finish, whereas 'EF' denotes epoxy. Ensure the procurement documentation explicitly references the Central Technologies manufacturer and the complete part number CTH6VF-270K to distinguish it from similar series components like the CTH8F or CTH6F variants which may have different electrical characteristics or physical dimensions.

Fixed Inductors Selection Notes

Select this component when an unshielded axial inductor with 27 µH inductance is required for through-hole assembly. Consider the 220 mΩ DC resistance limit for current handling requirements and the 8.0 MHz self-resonant frequency for high-frequency application suitability. Confirm that the varnish coating meets the environmental protection needs of the target circuit board.

Fixed Inductors Part Context

This component belongs to the CTH6VF series of fixed inductors manufactured by Central Technologies. The series offers various inductance values in an axial wirewound format. The CTH6VF-270K specifically represents the 27 µH variant within this lineup, characterized by its unshielded design and varnish coating, distinguishing it from shielded or epoxy-coated alternatives in the broader product catalog.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 27 µH inductance, axial form factor, and through-hole mounting style. Verify that any replacement component maintains comparable DC resistance and self-resonant frequency specifications to ensure circuit compatibility without requiring layout modifications.
