Arrays, Signal Transformers Procurement Notes

Verify the specific suffix 'R' against official datasheets to confirm reel packaging requirements. Confirm that the 1.0 A current rating aligns with thermal management capabilities in the final assembly. Ensure SMT pad layouts match the 11.54 x 11.54 mm package dimensions provided in the manufacturer documentation.

Arrays, Signal Transformers Selection Notes

Select this component when dual-channel inductance is required in a single SMD package. Compare the 19.6 µH value against circuit simulation results for ripple current requirements. Evaluate the 0.146 Ω DCR impact on overall efficiency relative to alternative discrete inductors or other OCTA-PAC variants.

Arrays, Signal Transformers Part Context

This part belongs to the Eaton CTX series of coupled inductors, utilizing amorphous metal cores. The OCTA-PAC branding indicates a specific form factor designed for high-density mounting. It serves as a specialized passive component for managing magnetic coupling in multi-phase or dual-output power supply architectures.

Arrays, Signal Transformers Replacement Considerations

Consult the official Eaton cross-reference guide for verified substitutes. Alternative models may include different inductance values or current ratings within the same CTX series. Verify pin compatibility and thermal characteristics before substitution.
