Common Mode Chokes Procurement Notes

Verify the specific suffix AE against official Bourns documentation to confirm the exact winding type and packaging specifications. Ensure the selected variant matches the required inductance tolerance and current rating for the target application circuit. Cross-reference the datasheet revision date to confirm parameter validity before finalizing procurement orders.

Common Mode Chokes Selection Notes

Select this component when a low-profile surface-mount solution is required for data line protection. The 500 mA current rating suits moderate signal applications. Verify that the 25 µH inductance value aligns with the intended frequency attenuation requirements. Confirm compatibility with standard SMD reflow soldering profiles based on the thermal characteristics defined in the manufacturer's datasheet.

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 and winding configurations to address different EMI suppression needs. The DR331-253AE specifically provides a 25 µH option with sector winding, designed for space-constrained printed circuit board layouts requiring efficient common mode noise filtering.

Common Mode Chokes Replacement Considerations

Consult the official Bourns DR331 series datasheet for confirmed substitute part numbers. Direct replacements must match the 25 µH inductance, 500 mA current rating, and compatible physical footprint to ensure functional equivalence without redesigning the PCB layout.
