LCFE160804H101TG

Common Mode Chokes Overview

LCFE160804H101TG is a surface-mount common mode choke from the LCFE series, designed for high-speed differential line filtering. It features four lines with a nominal impedance of 100 Ohms at 100 MHz and a tolerance of 25%. The component supports a maximum DC current of 100 mA and has a maximum DC resistance of 8 Ohms. It operates within a temperature range of -40°C to +85°C and utilizes an 0603 (1608 metric) package with eight leads.

Common Mode Chokes Feature Summary

• Provides effective suppression of common mode noise with high insertion loss exceeding -35 dB in the GHz range.
• Features a high differential mode cutoff frequency up to 10.35 GHz for signal integrity preservation.
• Ensures reliability through guaranteed high-temperature soldering capability at 260°C for 10 seconds.

Common Mode Chokes Applications

• High-speed data interface protection
• Differential signal line filtering
• Common mode noise attenuation in compact PCB designs

Common Mode Chokes Procurement Notes

Verify the specific manufacturer part number against official Littelfuse documentation to confirm electrical characteristics and package dimensions. Ensure that the selected component meets the required impedance tolerance and thermal specifications for the target application environment before finalizing procurement.

Common Mode Chokes Selection Notes

Select this component when designing circuits requiring multi-line common mode filtering in ultra-thin form factors. Consider the 100 mA current rating and 8 Ohm DCR limits to ensure compatibility with the power budget. The 100 MHz impedance specification should align with the operating frequency of the protected signals.

Common Mode Chokes Part Context

This device belongs to the LCFE series of common mode chokes manufactured by Littelfuse Inc. The series is characterized by its ability to handle high-frequency noise while maintaining a low profile suitable for space-constrained electronic assemblies.

Common Mode Chokes Replacement Considerations

The TDK TCM1608G-900-4P-T200 is identified as a similar replacement option. Note that the TCM1608G series is marked as obsolete, making the Littelfuse alternative a viable source for continued supply.
