CTS4F-472K

Fixed Inductors Overview

The CTS4F-472K is a fixed axial leaded inductor from Central Technologies, designed for general-purpose applications. It features a shielded molded construction with an amorphous magnetic core, providing robust performance in RF circuits. The component offers a nominal inductance of 4700 µH (4.7 mH) with a tolerance of ±10%. Key electrical specifications include a maximum DC resistance of 51 Ω, a minimum quality factor of 70 at the nominal inductance, and a self-resonant frequency of 1.7 MHz. It supports a maximum rated current of 68 mA and operates within a temperature range of -55 °C to 125 °C.

Fixed Inductors Feature Summary

• Shielded molded wirewound construction minimizes electromagnetic interference
• Amorphous magnetic core material ensures stable inductance characteristics
• Axial leaded package facilitates through-hole mounting on printed circuit boards

Fixed Inductors Applications

• RF filter circuits requiring high inductance values
• General-purpose signal processing applications
• Power supply filtering where shielding is necessary

Fixed Inductors Procurement Notes

Verify the specific part number suffix against official Central Technologies documentation to confirm tolerance and packaging details. Ensure that the required operating current does not exceed the 68 mA rating to prevent thermal issues. Confirm compliance with relevant environmental standards such as RoHS before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when a shielded axial inductor with high inductance is required for RF or general-purpose applications. Consider the 51 Ω DC resistance and 68 mA current limit during circuit design. Compare with unshielded alternatives if EMI sensitivity is low, but prioritize this model for noise reduction requirements.

Fixed Inductors Part Context

The CTS4F series represents Central Technologies' line of shielded axial inductors. These components are engineered for reliability in demanding electronic environments. The CTS4F-472K specifically targets applications needing significant inductance in a compact, shielded form factor, distinguishing it from open-core variants.

Fixed Inductors Replacement Considerations

Direct substitutes may include other CTS4F series parts with similar inductance and current ratings. Verify physical dimensions and pin compatibility when replacing. Cross-reference with manufacturer datasheets to ensure equivalent electrical performance and thermal characteristics.
