Arrays, Signal Transformers Procurement Notes

Verify the specific revision status and RoHS compliance details directly with Eaton Electronics or authorized distributors before procurement. Confirm that the 146 mΩ DCR and 1.3 A rating align with your circuit design requirements. Ensure the 4-pin SMT footprint matches your PCB layout constraints. Check for any recent Product Change Notifications regarding packaging or material composition updates.

Arrays, Signal Transformers Selection Notes

Select this component when a compact, high-current coupled inductor is required for space-constrained designs. The 32.63 µH value suits intermediate frequency switching applications. Compare the 146 mΩ resistance against thermal dissipation limits in your enclosure. Consider the 1.3 A current rating relative to peak load conditions and derating factors at elevated temperatures.

Arrays, Signal Transformers Part Context

This part belongs to the Eaton Econo-Pac series, which offers cost-effective magnetics solutions. The CTX33-3P-R shares physical characteristics with other parts in the CTX33 family, such as the CTX33-2P-R, but differs in electrical specifications like inductance and pin configuration.
