2743005111

Overview

The Fair-Rite Products Corp. 2743005111 is an axial leaded ferrite bead designed for electromagnetic interference suppression. It utilizes Fair-Rite Material 43, providing high impedance in the frequency range of 25 MHz to 300 MHz. The component exhibits an impedance of 103 Ohms at 100 MHz and 90 Ohms at 250 MHz. It features a single-line configuration with axial leads for through-hole mounting. The device operates within a temperature range of -55°C to +125°C and complies with RoHS standards.

Feature Summary

• Utilizes Fair-Rite Material 43 for effective noise attenuation across broad frequency bands
• Axial leaded construction facilitates standard through-hole PCB integration
• Single-line design targets common-mode noise on individual conductors

Applications

• Electromagnetic interference suppression in electronic circuits
• Signal line filtering for data transmission cables
• Power supply input/output noise reduction

Procurement Notes

Verify the specific impedance tolerance and DC resistance values against the official manufacturer datasheet prior to finalizing the bill of materials. Confirm that the axial lead spacing matches the target printed circuit board layout dimensions. Ensure the operating temperature rating aligns with the environmental conditions of the intended application to guarantee long-term reliability and performance stability.

Selection Notes

Select this component when broadband noise suppression is required using Material 43 characteristics. The axial form factor is suitable for applications where surface-mount space is unavailable or where mechanical strain relief via leads is necessary. Compare impedance profiles against competing materials if specific frequency targeting is critical for the noise spectrum present in the system.

Part Context

This part belongs to the Fair-Rite ferrite bead series, specifically utilizing Material 43 known for its high permeability and resistivity. It serves as a passive component for EMI control, distinct from split-core or snap-on rings. The axial lead style differentiates it from chip-style beads, offering robust mechanical connection for wiring harnesses or direct board mounting.

Replacement Considerations

Substitute parts must match the 103 Ohm @ 100 MHz impedance profile and utilize Material 43 composition. Verify equivalent axial lead dimensions and current carrying capacity. Cross-reference with other manufacturers' ferrite beads offering similar frequency response curves to ensure functional compatibility without altering circuit impedance characteristics.
