Overview
The Fair-Rite Products Corp. model 2743002112 is an axial leaded ferrite bead utilizing Material 43 composition. It provides an impedance of 158 Ohms at a test frequency of 100 MHz. The component features a round cable geometry with a length of 6.7 mm and a diameter of 3.5 mm. It operates within a temperature range from -55°C to +125°C. The unit weighs approximately 500 mg and is designed for broadband EMI suppression at lower frequencies.
Feature Summary
- Axial leaded construction for through-hole integration
- Material 43 composition for broadband noise attenuation
- Round solid core design for cable wrapping
Applications
- EMI suppression on signal cables
- Power line noise filtering
- Data bus protection
Procurement Notes
Verify the specific impedance tolerance and DC bias characteristics against the official Fair-Rite datasheet before finalizing the design. Confirm that the axial lead pitch and physical dimensions fit the target PCB footprint or cable assembly constraints. Ensure the operating temperature range meets the environmental requirements of the end application.
Selection Notes
Select this component when broadband attenuation is required for cables carrying signals in the MHz range. The Material 43 formulation offers high permeability suitable for suppressing common mode noise. Compare the 158 Ohm impedance value against other series beads to ensure adequate attenuation without excessive insertion loss for the specific signal integrity needs.
Part Context
This part belongs to the Fair-Rite 27 series of ferrite beads on leads. These components are distinct from snap-on cores as they feature integrated axial leads, facilitating direct soldering to circuit boards. They are commonly used in conjunction with other EMI suppression techniques to meet regulatory compliance standards for electromagnetic interference.
Replacement Considerations
Cross-reference with Fair-Rite part number 2743002112L or 2743002112LF for identical specifications. Verify compatibility with alternative suppliers offering Material 43 axial beads with similar 158 Ohm @ 100 MHz impedance ratings.
