• High-speed digital interface protection

Procurement Notes

Verify the specific suffix and tape-and-reel specifications against the manufacturer's latest datasheet before ordering. Confirm that the AEC-Q200 certification status aligns with your project's automotive quality requirements. Ensure the surface mount footprint matches your PCB layout constraints to prevent assembly errors.

Selection Notes

Select this component when filtering high-frequency common mode noise in automotive circuits without introducing significant series resistance. The 3.8A rating accommodates moderate current loads while maintaining effective attenuation at 100 MHz. Consider the physical dimensions and terminal availability for integration into compact electronic assemblies.

Part Context

This part belongs to the WCM5555FASV series of common mode chokes from TAI-TECH. The series offers various impedance levels tailored for different frequency suppression needs. The '701' designation specifically indicates the 700 Ohm impedance characteristic at the standard test frequency of 100 MHz.

Replacement Considerations

Cross-reference with other AEC-Q200 qualified two-line chokes offering similar 700 Ohm impedance and 3.8A current ratings. Verify pin compatibility and inductance curves to ensure equivalent noise suppression performance in the target application.
