Common Mode Chokes Procurement Notes

Verify the specific impedance tolerance rating of 50% against design requirements, as this differs from standard 25% variants. Confirm that the 4.8 A current rating aligns with the application's peak load conditions. Ensure the 5.5x5.5 mm footprint matches the PCB layout constraints. Cross-reference the datasheet for thermal derating curves relevant to the operating environment.

Common Mode Chokes Selection Notes

Select this component when high current handling capability is required alongside effective common mode noise suppression. The 300 Ohm impedance provides attenuation for high-frequency interference without significant signal degradation. Consider the unshielded nature of the device for placement relative to sensitive components. The wide temperature range supports operation in demanding industrial environments.

Common Mode Chokes Part Context

This part belongs to the Vishay Dale ICM series of common mode chokes. These components utilize ferrite cores and paired windings to suppress electromagnetic interference. The ICM series is engineered for reliability in compact surface mount configurations, offering consistent performance across various electronic systems requiring noise reduction on power or data lines.

Common Mode Chokes Replacement Considerations

Substitutes must match the 300 Ohm impedance at 100 MHz and support at least 4.8 A DC current. Verify compatible package dimensions of 5.5 mm x 5.5 mm x 3.5 mm. Ensure equivalent DC resistance and temperature range specifications are met by alternative manufacturers.
