2743008112

Overview

The Fair-Rite Products Corp. model 2743008112 is an axial leaded ferrite bead designed for electromagnetic interference (EMI) suppression. It utilizes Fair-Rite Material 43, providing high permeability for effective noise attenuation in the broadband frequency range. The component exhibits a nominal impedance of 180 Ohms at a test frequency of 100 MHz. It features an axial termination type and is rated for an operating temperature range from -55°C to +125°C.

Feature Summary

• Constructs with Material 43 ferrite composition for broad-spectrum EMI suppression capabilities
• Features axial leads for through-hole mounting on printed circuit boards
• Provides 180 Ohms impedance at 100 MHz to attenuate high-frequency noise

Applications

• Suppression of common mode noise on data lines
• Filtering power supply input and output traces
• Noise reduction on communication interface cables

Procurement Notes

Verify the specific material designation matches the required frequency response profile for your application. Confirm that the axial lead spacing and physical dimensions are compatible with your PCB footprint or cable assembly constraints. Ensure the 180 Ohm impedance value at 100 MHz aligns with the target noise frequencies. Check RoHS compliance status if restricted substances are prohibited in your manufacturing process.

Selection Notes

Select this component when broadband noise suppression is required across lower and mid-range frequencies. Material 43 offers higher permeability than standard materials, making it suitable for applications where significant inductance is needed in a compact form factor. Consider the thermal rating of +125°C for environments with elevated ambient temperatures. Evaluate the DC resistance characteristics if current carrying capacity is a critical design parameter.

Part Context

This part belongs to the Fair-Rite series of ferrite beads on leads. These components are distinct from snap-on cores as they are integrated directly onto wire leads during manufacturing. They serve as passive filters to dampen high-frequency oscillations without affecting the desired signal integrity. The axial configuration allows for easy integration into existing wiring harnesses or board layouts.

Replacement Considerations

Substitute parts must maintain the same Material 43 composition to ensure equivalent magnetic properties. Verify that the replacement offers comparable impedance at 100 MHz and similar thermal stability limits. Physical lead spacing and overall length should match to fit existing mechanical constraints.
