LCF201204A181TG

Common Mode Chokes Overview

The Littelfuse LCF201204A181TG is a surface-mount common mode choke designed for high-speed differential line filtering. It features four channels with an impedance of 180 Ohms at 100 MHz and a maximum DC current rating of 100 mA. The component utilizes an 0805 (2012 Metric) package with eight leads and a lead spacing of 0.65 mm. It offers a tolerance of 25% and includes a DCR of 4 Ohms, providing compact EMI suppression for signal lines.

Common Mode Chokes Feature Summary

• High-speed differential line filtering capability
• Compact surface-mount design in an 0805 package
• Four-channel configuration for multi-line applications

Common Mode Chokes Applications

• Signal line EMI suppression
• High-speed data interface protection
• Differential signal integrity maintenance

Common Mode Chokes Procurement Notes

Verify the specific suffix 'A' and 'T' against official Littelfuse documentation to confirm impedance tolerance and packaging type. Ensure the 100 mA current rating aligns with circuit requirements. Confirm the 0805 footprint dimensions match PCB layout constraints before finalizing procurement orders.

Common Mode Chokes Selection Notes

Select this component when space-constrained designs require four-channel common mode filtering. The 180 Ohm impedance at 100 MHz suits high-frequency noise attenuation. Verify that the 100 mA current limit meets the operational load of the target signal lines without saturation.

Common Mode Chokes Part Context

This part belongs to the LCF series of common mode chokes from Littelfuse. These components are engineered for suppressing electromagnetic interference in compact electronic assemblies. The series supports various impedance values and channel counts to accommodate diverse signal processing needs.

Common Mode Chokes Replacement Considerations

Check Littelfuse datasheets for alternative part numbers within the LCF series offering similar 180 Ohm impedance and 4-channel configurations. Ensure any substitute maintains the 0805 footprint and 100 mA current rating for direct compatibility.
