Impedance reaches 700 Ohms at a frequency of 3.35 MHz. It operates within a temperature range of -40°C to +125°C and meets AEC-Q200 qualification standards.

Common Mode Chokes Feature Summary

• Provides effective common mode noise suppression for dual-line circuits
• Capable of handling high continuous DC currents up to 30 A
• Constructed with a shielded molded core for compact integration

Common Mode Chokes Applications

• High-current power line filtering
• Automotive electronic systems requiring AEC-Q200 compliance
• Noise suppression in DC-DC converter outputs

Common Mode Chokes Procurement Notes

Verify the specific package dimensions against design constraints, as sources indicate variations such as 23 mm x 24.3 mm x 22.7 mm or horizontal pad configurations. Confirm that the 190 uH inductance and 1.35 mOhm DCR values align with circuit requirements. Ensure the supplier provides official datasheets to validate the AEC-Q200 automotive qualification status before finalizing procurement.

Common Mode Chokes Selection Notes

Select this component when designing circuits that require robust common mode rejection for high-current DC lines. The low DC resistance minimizes power loss, while the high saturation current capability ensures stability under heavy loads. Consider the physical footprint carefully, as dimensional data varies across distributor listings, potentially indicating different mechanical variants within the same electrical specification family.

Common Mode Chokes Part Context

This part belongs to the PA5140 series of common mode chokes from Pulse Electronics. It is categorized under Inductors, Chokes & Coils and serves as a surface-mount solution for EMI mitigation. Unlike the PA4341 power inductor series which focuses on energy storage, this component is specialized for differential signal integrity and noise cancellation in multi-wire power transmission paths.

Common Mode Chokes Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Engineers should consult manufacturer cross-reference guides for equivalent components with matching 30 A current ratings and similar impedance characteristics.
