2761008112

Overview

The Fair-Rite Products Corp. part number 2761008112 is an axial leaded ferrite bead designed for electromagnetic interference (EMI) suppression. It utilizes material composition 112, which provides specific impedance characteristics at radio frequencies. The component features a minimum impedance of 163 Ohms measured at a test frequency of 100 MHz. This solid-state device is constructed to handle signal lines where conducted noise reduction is required without introducing significant series resistance.

Feature Summary

• Provides controlled impedance for EMI suppression in signal and power lines
• Utilizes Material 112 composition for specific high-frequency attenuation properties
• Features axial leads for through-hole mounting on printed circuit boards

Applications

• Suppression of conducted EMI in digital signal lines
• Noise filtering in communication equipment interfaces
• EMI mitigation in computer peripheral connections

Procurement Notes

Verify the exact impedance specification against the manufacturer's current datasheet before integration. Confirm that the axial lead configuration matches the target PCB footprint requirements. Ensure the Material 112 composition aligns with the intended frequency range of the application. Check RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when axial mounting is preferred over surface mount alternatives. Choose Material 112 specifically for its impedance profile at 100 MHz. Consider the physical size constraints of the housing or enclosure during layout. Evaluate the current carrying capacity relative to the signal line load to prevent saturation or excessive heating.

Part Context

This component belongs to the Fair-Rite 'Beads-on-Leads' product family. These components are distinct from chip beads and toroidal cores, offering a compromise between ease of installation and performance. They are commonly used in prototyping and low-volume production where manual soldering is standard practice.

Replacement Considerations

Substitute parts must match the 163 Ohm minimum impedance at 100 MHz and utilize Material 112. Verify that the replacement offers identical axial lead spacing and physical dimensions to fit existing tooling and fixtures.
