Designed for compact surface-mount PCB integration
Constructed for reliable operation across extended industrial temperature ranges

Common Mode Chokes Applications

High-speed data interface filtering
USB port noise suppression
HDMI signal line protection

Common Mode Chokes Procurement Notes

Verify the specific suffix and tape/reel specifications against the manufacturer's latest datasheet before ordering. Confirm that the 750 mA current rating aligns with the target circuit's peak load requirements. Ensure the footprint matches the 9.60 mm by 5.80 mm land pattern defined in the official mechanical drawings to guarantee proper solder joint integrity during assembly.

Common Mode Chokes Selection Notes

Select this component when space-constrained designs require effective common mode attenuation for differential pairs. The low DCR minimizes signal loss while maintaining adequate impedance for noise reduction. Consider the 1.31 mH value at 100 kHz as the primary metric for determining cutoff frequency characteristics relative to the specific data rate being filtered.

Common Mode Chokes Part Context

This part belongs to Eaton's CMS series of surface-mount common mode chokes. These components are engineered for applications requiring efficient noise filtering in minimal board areas. The series typically offers various inductance and current ratings to suit different signal integrity needs in consumer and industrial electronics.
