2743014221

Overview

Fair-Rite Products Corp. part number 2743014221 is an axial leaded ferrite bead designed for electromagnetic interference suppression. The component utilizes Fair-Rite Material 46, providing a nominal impedance of 460 ohms at a single frequency point. It features a through-hole mounting configuration with a single line of connection. The device operates within a temperature range of -55°C to +125°C and complies with RoHS standards.

Feature Summary

• High impedance value suitable for broadband noise attenuation
• Axial leaded construction for standard through-hole integration
• Material 46 composition optimized for specific frequency suppression

Applications

• Electromagnetic interference (EMI) suppression on signal lines
• Common mode noise reduction in electronic assemblies
• Filtering high-frequency noise in power supply circuits

Procurement Notes

Verify the exact impedance specification against the official datasheet before procurement, as material 46 characteristics vary by frequency. Confirm that the axial lead length and diameter match your PCB footprint requirements. Ensure the operating temperature range meets your environmental conditions. Check for any specific packaging constraints if ordering in bulk quantities.

Selection Notes

Select this component when a high-impedance barrier is required at a specific target frequency. Material 46 offers different magnetic properties compared to common materials like 43 or 31. Evaluate the DC resistance and current carrying capacity to ensure it does not degrade circuit performance. Compare physical dimensions against available board space to confirm fitment.

Part Context

This part belongs to the Fair-Rite axial ferrite bead series, which are passive components used to suppress unwanted high-frequency signals. These beads act as frequency-dependent resistors, presenting high impedance to noise while allowing desired signals to pass. They are distinct from toroidal cores as they are pre-formed for direct circuit insertion.

Replacement Considerations

Substitute parts must match the 460 ohm impedance at the relevant frequency and utilize Material 46. Verify that replacement axial beads have compatible lead spacing and physical dimensions. Ensure the substitute component meets the same thermal and electrical ratings.
