DRQ125-101-R

Arrays, Signal Transformers Overview

The DRQ125-101-R is a shielded two-coil surface-mount inductor array from Eaton Electronics. It features a ferrite drum core and wire-wound construction within a 12.50mm x 12.50mm x 6.00mm package. The component provides an inductance of 102.7 µH in parallel connection and 410.8 µH in series connection, with a tolerance of ±20%. DC resistance is 170 mΩ in parallel and 682 mΩ in series. Rated currents are 1.78 A (parallel) and 892 mA (series), with saturation currents of 2.2 A and 1.1 A respectively.

Arrays, Signal Transformers Feature Summary

• Dual-coil configuration allowing flexible series or parallel circuit integration
• Shielded drum core design minimizes electromagnetic interference
• Wire-wound construction on ferrite material for stable performance

Arrays, Signal Transformers Applications

• SEPIC converter circuits
• Power supply filtering
• DC-DC converter input/output stages

Arrays, Signal Transformers Procurement Notes

Verify the specific suffix 'R' indicates reel packaging when ordering. Confirm RoHS3 compliance status for environmental regulations. Ensure the dual-coil pinout matches the target schematic requirements before finalizing procurement. Cross-reference manufacturer part numbers to avoid confusion with single-coil variants.

Arrays, Signal Transformers Selection Notes

Select this component when dual inductors are required in a compact footprint. Compare parallel versus series current ratings against load requirements. Verify that the 170 mΩ parallel DCR meets efficiency targets. Ensure the 12.5mm square package fits the PCB layout constraints.

Arrays, Signal Transformers Part Context

This part belongs to the DRQ series of shielded power inductors. It shares physical dimensions with other DRQ models but differs in electrical characteristics. The series utilizes a common drum core architecture optimized for high-current applications.

Arrays, Signal Transformers Replacement Considerations

DR125-101-R is a single-coil alternative with similar electrical values but lacks the dual-array feature. Substitution requires circuit redesign to accommodate separate components.
