DR221-113AE

Common Mode Chokes Overview

The Bourns DR221-113AE is a surface mount common mode choke designed for data line applications. It features an inductance of 11 µH with a tolerance of +50%/-30% and offers an impedance of 450 Ohms at 10 kHz. The component supports a maximum DC current of 250 mA and has a maximum DC resistance of 180 mOhms per winding. It operates within a temperature range of -40°C to +125°C and measures 5 mm in length with a height of 3.3 mm.

Common Mode Chokes Feature Summary

• Surface mount construction for automated assembly
• Common mode filtering for signal integrity
• Compact footprint suitable for space-constrained designs

Common Mode Chokes Applications

• Data line protection
• Signal line filtering
• Electronic equipment noise suppression

Common Mode Chokes Procurement Notes

Verify the specific suffix AE against official Bourns documentation to confirm package and tape/reel specifications. Ensure the requested quantity matches distributor availability, as lead times vary by supplier. Confirm that the operating environment remains within the specified -40°C to +125°C range during installation and use.

Common Mode Chokes Selection Notes

Select this component when a compact surface mount solution is required for low-current data lines. The 250 mA rating suits sensitive signal circuits rather than power delivery. Verify that the 11 µH inductance meets the specific frequency attenuation requirements of the target application before finalizing the design.

Common Mode Chokes Part Context

This part belongs to the Bourns DR221 series of surface mount data line chokes. The series provides various inductance values for different filtering needs while maintaining a consistent small form factor. The DR221-113AE specifically targets applications requiring moderate inductance with high current handling relative to its size.

Common Mode Chokes Replacement Considerations

Consult the official Bourns DR221 series datasheet for direct substitutes with similar inductance and current ratings. Cross-reference pinout and mechanical dimensions to ensure compatibility with existing PCB layouts without redesigning traces or pads.
