Common Mode Chokes datasheet and documents for DR331-225BE

DR331-225BE

Common Mode Chokes Overview

The Bourns DR331-225BE is a surface-mount common mode choke designed for data line filtering. It features a bifilar winding configuration and a ferrite core, providing an inductance of 2.2 mH with a tolerance of ±25%. The component supports a maximum DC current of 300 mA and has a maximum DC resistance of 700 mOhms. It operates within a temperature range of -40°C to +135°C. Physical dimensions are 9 mm in length, 5.4 mm in width, and 4.7 mm in height, with a lead pitch of 3.7 mm.

Common Mode Chokes Feature Summary

Bifilar winding structure for enhanced common mode noise suppression
Ferrite core construction optimized for high-frequency EMI filtering
Surface mount package suitable for automated PCB assembly

Common Mode Chokes Applications

Data line filtering in electronic circuits
EMI suppression for signal transmission lines
Common mode noise reduction in communication interfaces

Common Mode Chokes Procurement Notes

Verify the specific suffix BE against the manufacturer's latest datasheet to confirm pinout and material compliance. Ensure the ordering quantity aligns with the factory reel size or cut tape availability. Confirm RoHS status and lead-free requirements match project specifications before finalizing procurement.

Common Mode Chokes Selection Notes

Select this component when a 2.2 mH inductance is required for common mode noise attenuation on data lines. The 300 mA current rating must accommodate the operating current without saturation. Consider the 9 mm x 5.4 mm footprint and 3.7 mm pitch for PCB layout compatibility. Verify thermal performance at the maximum operating temperature of 135°C.

Common Mode Chokes Part Context

This part belongs to the Bourns DR331 series of surface mount data line chokes. The series offers various inductance values tailored for different filtering requirements. These components utilize bifilar windings to maximize common mode impedance while maintaining low differential mode interference.
