Common Mode Chokes Procurement Notes

Verify the specific impedance tolerance and DC current ratings against the official Littelfuse datasheet before integration. Confirm that the 0806-4 package dimensions align with the target PCB land pattern. Ensure the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the manufacturer part number to avoid confusion with similar series components.

Common Mode Chokes Selection Notes

Select this component when space-constrained designs require effective common-mode noise filtering for differential signals. The low DC resistance minimizes signal loss, while the high impedance at 100 MHz ensures effective attenuation of high-frequency interference. Consider the 100 mA current rating to ensure adequate headroom for the application's operational currents without saturation.

Common Mode Chokes Part Context

This component belongs to the Littelfuse LCF series of common mode chokes. These devices are engineered specifically for suppressing electromagnetic interference in high-speed digital communication lines. The series offers various channel counts and impedance values to suit different signal integrity requirements across consumer and industrial electronics.

Common Mode Chokes Replacement Considerations

Check Littelfuse documentation for direct cross-references. Verify that any substitute maintains the 25 Ohm impedance at 100 MHz and fits the 0806-4 package. Ensure the replacement supports the required 100 mA current rating and -40°C to +85°C temperature range.
