2861000202

Overview

Fair-Rite 2861000202 is a multi-aperture ferrite core utilizing Material 61. It features two apertures with an inner diameter of 3.8 mm and an outer width of 13.3 mm. The component has an external length of 7.5 mm and provides an impedance of 190 ohms at 250 MHz. It is supplied in bulk packaging.

Feature Summary

• Dual-aperture design for simultaneous cable processing
• Material 61 composition for high-frequency noise suppression

Applications

• EMI suppression on dual-conductor cables
• Common mode choke implementation
• High frequency noise filtering

Procurement Notes

Verify the specific material grade and impedance specifications against the official Fair-Rite datasheet to ensure compatibility with target frequency ranges. Confirm physical dimensions match the required aperture sizes for the intended cable bundle. Check RoHS compliance status if required by project specifications.

Selection Notes

Select this component when dual-channel noise suppression is required within a compact footprint. Material 61 offers specific permeability characteristics suitable for higher frequency applications compared to standard mixtures. Ensure the cable diameter fits within the 3.8 mm inner diameter constraint.

Part Context

This part belongs to the Fair-Rite multi-aperture core series, designed for efficient space utilization in EMI suppression tasks. It differs from single-hole toroids by accommodating multiple conductors simultaneously without requiring separate components for each line.
