2761007111

Overview

The Fair-Rite Products Corp. model 2761007111 is an axial leaded ferrite bead designed for electromagnetic interference suppression. It features a solid core construction with a nominal impedance of 111 ohms at the standard test frequency of 100 MHz. The component utilizes Fair-Rite material composition 43, which provides high permeability suitable for broadband noise attenuation in the lower frequency range. The physical dimensions include a length of approximately 1 inch (25.4 mm) and a diameter of roughly 0.39 inches (9.9 mm). It is rated for operation within a temperature range of -55°C to +125°C and complies with RoHS directives.

Feature Summary

• Axial leaded configuration for through-hole mounting
• Solid core design for mechanical stability
• Material 43 composition for effective low-frequency noise suppression

Applications

• Suppression of common mode noise on data lines
• Filtering of radio frequency interference on power cables
• EMI reduction in computer peripheral connections

Procurement Notes

Verify the specific impedance tolerance and material batch consistency upon order confirmation. Confirm that the axial lead spacing matches your PCB footprint requirements. Ensure compliance with current environmental regulations such as RoHS and REACH for your target market. Check for any specific handling instructions regarding thermal stress during soldering processes.

Selection Notes

Select this component when broadband attenuation around 100 MHz is required for axial wiring applications. Material 43 is optimal for frequencies below 10 MHz where higher permeability is needed compared to other compositions. Consider the physical size constraints and lead formability before finalizing the design. Compare against split-core alternatives if retrofitting existing cables without disconnection is necessary.

Part Context

This part belongs to the Fair-Rite ferrite beads and chips category, specifically the axial leaded type. These components are distinct from snap-on cores or surface mount chips, offering a permanent solution for wire harnesses. The product line supports various materials tailored to different frequency spectra, with Material 43 being a widely used general-purpose option for EMI control.

Replacement Considerations

Direct substitutes may include other axial ferrite beads with similar 111-ohm impedance at 100 MHz and Material 43 composition. Verify dimensional compatibility, particularly the lead diameter and overall length, to ensure fitment. Alternative manufacturers should provide equivalent impedance curves across the relevant frequency spectrum.
