Arrays, Signal Transformers Procurement Notes

Verify the manufacturer part number DRQ74-8R2-R against official Eaton documentation to ensure authenticity. Confirm that the specific order suffix matches the required packaging format, such as tape and reel or cut tape. Check for recent Product Change Notifications regarding manufacturing lines or materials. Ensure compliance with RoHS3 standards and verify the moisture sensitivity level for storage and handling requirements before procurement.

Arrays, Signal Transformers Selection Notes

Select this component when a compact dual-inductor solution is required for power conversion topologies. The shielded design minimizes magnetic coupling with nearby components. Evaluate the parallel versus series current ratings based on the specific application load. The 7.60mm square footprint allows for dense board layouts. Verify that the operating temperature range meets the environmental conditions of the final device.

Arrays, Signal Transformers Part Context

This component belongs to the DRQ series of shielded drum core inductors from Eaton - Electronics Division. The series is designed for high-power applications requiring low profile and efficient thermal performance. The DRQ74 variant specifically denotes the 7.60mm x 7.60mm package size. These arrays are commonly used in telecommunications and industrial equipment where space constraints and EMI suppression are critical design factors.
