2944770301

Overview

Fair-Rite 2944770301 is a ferrite bead designed for broadband frequency suppression in the 10-300 MHz range. It utilizes Material 44 to achieve an impedance of 358 ohms at 100 MHz. The component features a radial termination style and axial lead configuration. Physical dimensions include a length of approximately 1 inch (25.4 mm) with a diameter of 0.138 inches (3.5 mm). It operates within a temperature range of -55°C to +125°C.

Feature Summary

• Utilizes Material 44 composition for effective broadband noise attenuation across high-frequency ranges.
• Features axial leads for through-hole mounting, facilitating integration into standard circuit board layouts.
• Provides high impedance characteristics specifically optimized for suppressing electromagnetic interference in the 10-300 MHz spectrum.

Applications

• Suppression of common-mode noise on data lines operating in broadband frequency ranges.
• Filtering high-frequency interference on power supply input and output traces.
• Noise reduction on signal cables connecting sensitive electronic components.

Procurement Notes

Verify the specific impedance value and material composition against the manufacturer's official datasheet before procurement. Confirm that the axial lead format matches your assembly requirements. Ensure the operating temperature range meets your environmental specifications. Check for RoHS compliance status if required by your regulatory framework. Validate the package type to ensure compatibility with your manufacturing process.

Selection Notes

Select this component when broadband suppression between 10 and 300 MHz is required. Material 44 offers higher permeability than Material 31, making it suitable for higher frequency applications. Consider the physical size and lead spacing for PCB layout constraints. Evaluate the thermal performance to ensure stability within the specified -55°C to +125°C range during operation.

Part Context

This part belongs to Fair-Rite's ferrite beads and chips category. It is distinct from open-core or toroidal cores due to its solid bead construction and integrated leads. The product line focuses on discrete components for direct circuit integration rather than cable-wrapping solutions.

Replacement Considerations

Substitute parts must match the 358 ohm impedance at 100 MHz and utilize Material 44. Axial leaded ferrite beads from other manufacturers may serve as alternatives if electrical parameters and physical dimensions are compatible. Verify that any replacement maintains the same broadband frequency coverage and temperature rating.
