LCFE160804A550TG

Common Mode Chokes Overview

The LCFE160804A550TG is a four-line common mode choke filter manufactured by Littelfuse Inc. in the LCFE series. It features a compact 1608 metric (0603) surface mount package with dimensions of 1.60mm x 0.80mm. The component provides an impedance of 55 Ohms at 100 MHz with a tolerance of 25%. It supports a maximum current rating of 100mA and includes ESD protection capabilities, making it suitable for high-speed differential line filtering applications.

Common Mode Chokes Feature Summary

• Four-line configuration for simultaneous noise suppression across multiple signal paths
• High insertion loss exceeding -35 dB for effective common mode noise attenuation in the GHz range
• Integrated ESD protection to safeguard sensitive circuitry from electrostatic discharge events

Common Mode Chokes Applications

• High-speed differential data lines requiring common mode noise filtering
• Portable electronic devices with limited board space constraints
• Interfaces susceptible to electromagnetic interference in compact form factors

Common Mode Chokes Procurement Notes

Verify the specific suffix 'TG' against official Littelfuse documentation to confirm tape and reel packaging specifications. Ensure the 1608 footprint matches the target PCB layout. Confirm that the 100mA current rating aligns with the operational requirements of the intended application to prevent saturation or thermal issues during normal operation.

Common Mode Chokes Selection Notes

Select this component when multi-line noise suppression is required within a minimal surface area. The 1608 package size offers a significant footprint reduction compared to larger chokes. Evaluate the 55 Ohm impedance value against the target frequency spectrum to ensure adequate attenuation. Verify compatibility with automated pick-and-place equipment due to the small SMD dimensions.

Common Mode Chokes Part Context

This part belongs to the Littelfuse LCFE series, which focuses on high-performance common mode filters for modern electronics. The series emphasizes miniaturization without compromising noise suppression efficiency. The LCFE160804A550TG specifically addresses the need for robust ESD protection and high-frequency filtering in densely packed consumer and industrial devices.

Common Mode Chokes Replacement Considerations

Consult Littelfuse official substitution guides for verified alternatives. Cross-reference impedance values and physical dimensions to ensure mechanical fit. Verify that any substitute maintains the four-line configuration and equivalent current ratings.
