2752555577

Overview

Fair-Rite 2752555577 is a differential-mode ferrite chip bead from the 27 series, designed for surface-mount applications. It utilizes Material 52 to provide high impedance in the 100 MHz range, specifically rated at 700 Ohms. The component supports a maximum DC current of 5 A with a low DC resistance of 6.2 mOhms. Physical dimensions are 11 mm in length, 5 mm in width, and 5 mm in height. It operates within a temperature range of -55°C to +125°C and is available in cut tape or reel packaging.

Feature Summary

• Differential mode suppression capability for noise reduction
• High current handling capacity suitable for power lines
• Low insertion loss due to minimal DC resistance
• Surface-mount design for automated assembly

Applications

• Power supply output filtering
• Data line noise suppression
• EMI mitigation in compact electronic devices

Procurement Notes

Verify the specific impedance rating against project requirements, as sources indicate variations between 640 Ohms and 700 Ohms at 100 MHz. Confirm the package type matches the PCB footprint, as both cut tape and reel options are listed. Ensure the manufacturer lead time aligns with production schedules, given the stated twenty-week cycle. Cross-reference the material number to confirm compatibility with the target frequency spectrum.

Selection Notes

Select this component when differential mode noise attenuation is required on high-current lines. The five-ampere rating makes it suitable for power delivery networks where standard beads might saturate. The Material 52 composition offers effective performance in the VHF range. Consider the physical size constraints, as the eleven-millimeter length may require specific board layout planning compared to smaller footprints.

Part Context

This part belongs to Fair-Rite's 27 series of ferrite chips, which are engineered for surface-mount technology. The series focuses on providing robust EMI suppression in space-constrained environments. Material 52 is selected for its specific permeability characteristics, balancing impedance magnitude with current handling capabilities for modern electronic designs.

Replacement Considerations
