LCFE060502A650TG

Common Mode Chokes Overview

The LCFE060502A650TG is a two-line common mode choke manufactured by Littelfuse Inc. It features a surface mount design with a maximum thickness of 0.35 mm. The component provides a common mode impedance of 65 Ohms at 100 MHz, with a tolerance of ±25%. It supports a current rating of 50 mA and has a DC resistance (DCR) of 8 Ohms. The device exhibits a cut-off frequency of 4.76 GHz.

Common Mode Chokes Feature Summary

• Designed for effective suppression of common mode noise in high-frequency applications
• Provides high insertion loss exceeding -31 dB for common mode noise attenuation within the GHz range
• Maintains high differential signal integrity while filtering electromagnetic interference

Common Mode Chokes Applications

• EMI filtering for electronic circuits
• ESD protection components
• High-speed data line noise suppression

Common Mode Chokes Procurement Notes

Verify the specific impedance tolerance and current ratings against the official Littelfuse datasheet before integration. Confirm that the surface mount package dimensions align with your PCB footprint requirements. Ensure the operating environment does not exceed the thermal limits specified for the 50 mA rating. Cross-reference the part number suffix to confirm material composition and lead-free status as required by your assembly standards.

Common Mode Chokes Selection Notes

Select this component when space-constrained designs require low-profile EMI filtering. The 0605 footprint suits compact consumer electronics. The 50 mA rating indicates suitability for low-power signal lines rather than power delivery. Evaluate the 65 Ohm impedance against the target noise spectrum to ensure adequate attenuation without compromising signal quality.

Common Mode Chokes Part Context

This component belongs to the LCFE0605 series from Littelfuse. The series focuses on providing compact solutions for electromagnetic interference suppression. These chokes are engineered to meet the demands of modern portable devices where size and performance are critical constraints.

Common Mode Chokes Replacement Considerations

Consult the Littelfuse LCFE series compatibility matrix for direct substitutes. Verify that any alternative maintains the 0605 footprint and 50 mA current handling capability. Ensure the replacement offers comparable impedance characteristics at 100 MHz.
