LCFE160804A350TG

Common Mode Chokes Overview

The LCFE160804A350TG is a four-line common mode choke from the Littelfuse LCFE series, designed for surface mount applications in the 0603 (1608 metric) package. It provides an impedance of 35 Ohms at 100 MHz with a rated current of 100 mA and a DC resistance of 6 Ohms. The component ensures high insertion loss exceeding -35 dB for common mode noise attenuation in the GHz range and features a high differential mode cut-off frequency up to 10.35 GHz. It supports high-temperature soldering at 260°C for 10 seconds.

Common Mode Chokes Feature Summary

• Effective suppression of common mode noise through high insertion loss in the GHz range
• High differential mode cut-off frequency ensuring signal integrity
• Thin profile design suitable for space-constrained surface mount layouts
• Robust construction guaranteed for high-temperature soldering processes

Common Mode Chokes Applications

• High-speed differential line filtering
• Common mode noise filter circuits
• ESD protection systems

Common Mode Chokes Procurement Notes

Verify the specific impedance value and current rating against the official Littelfuse datasheet before integration. Confirm that the 0603 package dimensions align with the target PCB footprint. Ensure the supplier provides documentation confirming compliance with RoHS standards and the specified high-temperature soldering capability to guarantee reliability during assembly.

Common Mode Chokes Selection Notes

Select this component when designing compact high-speed interfaces requiring effective common mode noise rejection without compromising differential signal quality. The 100 mA rating suits low-power data lines. Consider the thin profile for devices with strict height restrictions. Validate that the 35 Ohm impedance matches the system's noise environment requirements at the operating frequency.

Common Mode Chokes Part Context

This part belongs to the LCFE1608 series of common mode chokes manufactured by Littelfuse Inc. The series is characterized by its ultra-thin form factor and high-performance filtering capabilities in a small surface mount package. These components are engineered to meet the demands of modern electronics where space is limited and signal integrity is critical.

Common Mode Chokes Replacement Considerations

The LCFE160804A550TG is a confirmed substitute within the same series, offering 55 Ohms impedance instead of 35 Ohms. Verify if the higher impedance meets the specific noise suppression requirements of the application.
