Overview
Fair-Rite part number 2873001502 is a solid multi-aperture ferrite core utilizing Material Grade 73. It features an inner diameter of 3.80 mm (0.150 inches), an outer diameter of 7.50 mm (0.295 inches), and a length of 6.60 mm (0.260 inches). The component provides an impedance of 57 ohms at 10 MHz and 52 ohms at 25 MHz.
Feature Summary
- Multi-aperture design allows for the passage of multiple conductors through a single magnetic structure.
- Material Grade 73 composition offers high permeability suitable for broadband transformer applications.
Applications
- Common mode chokes for multi-conductor cables
- Broadband transformer cores
- EMI suppression on signal lines
Procurement Notes
Verify the specific material grade and impedance characteristics against your circuit requirements before ordering. Confirm that the physical dimensions, particularly the inner diameter, accommodate the cable bundle or conductor size intended for use. Ensure compliance with relevant environmental regulations such as RoHS if applicable to your manufacturing process.
Selection Notes
Select this component when a multi-hole configuration is required for simultaneous cable management and noise suppression. Material 73 is appropriate for applications requiring higher inductance values compared to lower permeability materials. Evaluate the operating frequency range to ensure the impedance profile meets the attenuation needs of the specific EMI spectrum being addressed.
Part Context
This part belongs to Fair-Rite's 28 series of multi-aperture ferrite cores. These components are distinct from standard toroidal rings due to their multiple holes, which facilitate the routing of several wires through a single magnetic path for efficient common-mode noise reduction.
Replacement Considerations
Direct substitutes must match the multi-aperture geometry and Material 73 specifications. Verify dimensional compatibility with existing cable assemblies. Alternative materials may require recalibration of impedance performance at target frequencies.
