2873002702

Overview

Fair-Rite 2873002702 is a multi-aperture ferrite core utilizing Material 73. It features a binocular geometry with two circular apertures, each having a diameter of 1.7 mm. The component measures 7.01 mm in length and 4.20 mm in outer diameter. It provides an impedance of 44 ohms at 25 MHz and has an initial permeability (µi) of 2500.

Feature Summary

• Binocular dual-aperture design for simultaneous cable management
• Material 73 composition optimized for high-frequency noise suppression
• High initial permeability for effective common-mode choke applications

Applications

• Common-mode chokes for data lines
• EMI suppression on multi-conductor cables
• Noise filtering in high-speed digital circuits

Procurement Notes

Verify the specific material grade and impedance characteristics against your circuit requirements. Confirm that the aperture dimensions accommodate the target cable bundle diameter. Ensure compliance with relevant environmental regulations such as RoHS if applicable to your manufacturing process.

Selection Notes

Select this component when dual-cable routing within a single magnetic structure is required. Material 73 is suitable for frequencies typically above 10 MHz. Verify that the physical size fits within the available enclosure space and that the thermal properties meet operational demands.

Part Context

This part belongs to Fair-Rite's binocular ferrite core series, designed specifically for handling multiple conductors through a single magnetic path. The binocular shape allows for balanced winding and efficient use of space compared to standard toroidal cores for similar applications.

Replacement Considerations

Check Fair-Rite datasheets for other Material 73 binocular cores with compatible dimensions. Verify impedance curves at operating frequencies to ensure equivalent performance. Physical mounting constraints must be matched.
