DRQ127-101-R

Arrays, Signal Transformers Overview

The DRQ127-101-R is a shielded, wire-wound surface-mount inductor from Eaton's DR series. It features a ferrite drum core and offers an inductance of 100 µH with ±20% tolerance. The component supports a saturation current (Isat) of 3.64 A and a rated DC current (Irms) of 1.96 A. It has a maximum DC resistance of 163 mΩ and operates within a temperature range of -40°C to +125°C. Dimensions are 12.50 mm x 12.50 mm x 8.00 mm.

Arrays, Signal Transformers Feature Summary

• Shielded drum core construction minimizes electromagnetic interference.
• Wire-wound design on a ferrite core for high power handling.
• Surface mount package suitable for automated assembly.

Arrays, Signal Transformers Applications

Arrays, Signal Transformers Procurement Notes

Verify the manufacturer part number DRQ127-101-R against official Eaton documentation to ensure correct specifications. Confirm that the required inductance, current ratings, and physical dimensions match the target circuit design before finalizing procurement orders.

Arrays, Signal Transformers Selection Notes

Select this component when a shielded, high-current SMD inductor is required. Ensure the application current does not exceed the 1.96 A rated or 3.64 A saturation limits. Verify that the 12.50 mm footprint and 8.00 mm height fit the PCB layout constraints.

Arrays, Signal Transformers Part Context

This part belongs to the DR series of shielded drum core inductors. It is distinct from single-coil variants like the DR127-101-R and multi-coil arrays like the DRQ127-100-R. The '101' suffix indicates the 100 µH value, while 'R' denotes the reel packaging format.
