Common Mode Chokes Procurement Notes

Verify the specific suffix BE against official Bourns documentation to confirm exact electrical tolerances and packaging specifications. Ensure compatibility with peak reflow temperatures defined in the datasheet. Confirm RoHS compliance status for your region. Cross-reference the 120 mOhm DCR value with the latest manufacturer release notes to avoid discrepancies from older revisions.

Common Mode Chokes Selection Notes

Select this component when a low-profile 11 µH inductor is required for data lines with currents up to 0.5 A. The bifilar design offers superior common mode performance compared to standard single-wire chokes. Consider the 7.3 x 5.4 mm footprint for space-constrained layouts. Evaluate the 120 mOhm DC resistance impact on signal integrity for sensitive applications.

Common Mode Chokes Part Context

This part belongs to the Bourns DR331 series of surface mount data line chokes. The series provides various inductance values tailored for different frequency ranges. The DR331-113BE specifically targets applications requiring moderate inductance with high current handling capabilities in a small form factor.

Common Mode Chokes Replacement Considerations

Check Bourns DR331-103AE or DR331-253AE for alternative inductance values within the same series. Verify pinout and footprint compatibility before substituting with components from other manufacturers.
