Common Mode Chokes Procurement Notes

Verify the complete part number including the suffix TG against official Littelfuse documentation to ensure correct packaging and material specifications. Confirm that the 25 Ohm impedance rating aligns with the specific requirements of the target differential interface. Check RoHS compliance status through the manufacturer's official datasheet rather than distributor summaries.

Common Mode Chokes Selection Notes

Select this component when designing circuits requiring attenuation of common mode noise on three-channel differential pairs. Ensure the operating environment stays within the specified -45 C to +85 C range. Verify that the 80 mA current handling capacity meets the signal line requirements without causing excessive voltage drop across the 5 Ohm DC resistance.

Common Mode Chokes Part Context

This component belongs to the Littelfuse LPF Series LCF, which consists of common mode noise filters tailored for high-speed differential serial interfaces. The series addresses electromagnetic interference issues that can degrade video quality or introduce static in audio signals. These devices are engineered to maintain signal integrity in sensitive electronic applications.

Common Mode Chokes Replacement Considerations

Consult the official Littelfuse LPF Series datasheet for verified substitute part numbers. Cross-reference impedance values and channel counts to ensure functional equivalence. Do not assume compatibility based solely on physical dimensions.
