CTX0.47-4-R

Arrays, Signal Transformers Overview

The CTX0.47-4-R is a surface-mount power inductor array manufactured by Eaton Electronics Division under the OCTA-PAC series. This component features two independent coils with an inductance of 440 nH each and a tolerance of 20%. It has a maximum DC resistance of 0.016 ohms per coil and supports a maximum DC current of 3.50 A. The device utilizes a toroidal core structure and is supplied in tape and reel packaging for automated assembly.

Arrays, Signal Transformers Feature Summary

• Dual-coil configuration within a single compact SMD package
• Toroidal core design for efficient magnetic containment
• Automotive-grade reliability suitable for harsh environments

Arrays, Signal Transformers Applications

• Automotive electronics power filtering
• General-purpose power supply input/output stages
• EMI suppression in high-current circuits

Arrays, Signal Transformers Procurement Notes

Verify the specific OCTA-PAC datasheet for detailed thermal derating curves and soldering profiles. Confirm that the dual-coil topology meets the circuit requirements, as the components are electrically isolated but mechanically integrated. Ensure PCB layout accounts for the specified footprint dimensions to maintain signal integrity and thermal performance.

Arrays, Signal Transformers Selection Notes

Select this part when space-constrained designs require two inductors with identical specifications. The 440 nH value is optimized for high-frequency switching applications. Consider the 3.50 A current rating against peak load conditions to prevent saturation. The SMD format facilitates automated placement, reducing assembly costs compared to through-hole alternatives.

Arrays, Signal Transformers Part Context

Eaton Electronics Division produces the OCTA-PAC series to provide multi-inductor solutions in reduced footprints. These arrays replace multiple discrete components, simplifying bill-of-materials and improving board density. The series is widely used in automotive and industrial sectors where reliability and size efficiency are critical design parameters.

Arrays, Signal Transformers Replacement Considerations

Direct substitutes must match the 440 nH inductance, dual-coil structure, and similar current ratings. Verify pin compatibility and mechanical dimensions before substitution. Alternative manufacturers may offer comparable toroidal arrays, but electrical characteristics should be cross-referenced with official datasheets.
