• Robust ferrite core construction ensures stable performance across wide temperature ranges

Common Mode Chokes Applications

• High-speed serial interface protection
• USB port noise filtering
• Data line EMI suppression

Common Mode Chokes Procurement Notes

Verify the specific suffix 'S' against official Sumida documentation to confirm mechanical orientation or pinout variations compared to standard variants. Ensure compatibility with automated pick-and-place equipment regarding the horizontal gull-wing package profile. Cross-reference the 700 mA rating with system thermal requirements to prevent saturation during peak load conditions.

Common Mode Chokes Selection Notes

Select this component when designing circuits requiring 25 µH common mode attenuation for differential data signals. Consider the 0.16 Ω DC resistance impact on signal integrity and power loss. Evaluate the physical footprint constraints against available board space. Confirm that the operating temperature range meets the environmental specifications of the final assembly.

Common Mode Chokes Part Context

This part belongs to the CPFC54 series of surface-mount common mode chokes from Sumida. The series is designed for filtering electromagnetic interference in digital communication interfaces. It complements other components in the CD54 power inductor family but serves a distinct filtering function rather than energy storage.

Common Mode Chokes Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify cross-compatibility with generic 25 µH SMD common mode chokes only if electrical parameters and mechanical dimensions match exactly.
