CTRFB0810F-472K

Fixed Inductors Overview

The CTRFB0810F-472K is a fixed radial inductor manufactured by Central Technologies. It features an inductance of 4700 µH (4.7 mH) with a tolerance of ±10%. The component has a maximum DC resistance of 9.6 Ohms and a current rating of 280 mA. It utilizes a vertical cylinder package with radial leads for through-hole mounting.

Fixed Inductors Feature Summary

• Radial leaded construction for through-hole PCB integration
• Unshielded core design suitable for general-purpose filtering
• Vertical cylinder form factor for compact spatial arrangement

Fixed Inductors Applications

• Power supply input/output filtering
• Signal line noise suppression
• General electronic circuit impedance matching

Fixed Inductors Procurement Notes

Verify the specific suffix '472K' to confirm the 4.7 mH inductance value and ±10% tolerance. Ensure the 280 mA current rating and 9.6 Ohm DCR meet the target circuit requirements. Confirm the radial vertical package dimensions align with the PCB footprint before ordering.

Fixed Inductors Selection Notes

Select this component when a high-inductance, low-current radial inductor is required for unshielded applications. Compare the 280 mA saturation current against peak load conditions. Consider the 9.6 Ohm DC resistance impact on voltage drop within the signal or power path relative to alternative lower-resistance options.

Fixed Inductors Part Context

This part belongs to the CTRFB series of fixed inductors from Central Technologies. The series offers various inductance values ranging from microhenries to millihenries. The 472K variant specifically targets applications requiring higher inductance with moderate current handling capabilities in a standard radial package.

Fixed Inductors Replacement Considerations

Direct substitutes include other 4.7 mH radial inductors with similar current ratings and DCR. Verify pin compatibility and physical dimensions for equivalent replacement. Cross-reference with Central Technologies variants such as CTRFB0810F-102K for different electrical characteristics if available.
