2644246201

This Fair-Rite 2644246201 is a connector EMI suppression plate, a ferrite plate designed to suppress conducted EMI at critical interfaces. It measures 5.86mm x 3.86mm x 1.52mm and features 6 holes arranged in 2 rows, with a hole diameter of 2mm and pitch of 2mm. The plate is made of 44 NiZn ferrite material, known for high impedance and high resistivity.

Electrically, the plate provides a typical impedance of 14Ω at 25 MHz and 28Ω at 100 MHz. The material has an initial permeability of 500 µi, flux density of 3000 G at 10 Oe, residual flux density of 1100 G, and coercive force of 0.45 Oe. The loss factor at 1 MHz is 150×10⁻⁶ and the temperature coefficient of initial permeability is 1.6 %/°C over 20-70°C. The Curie temperature is greater than 160°C and resistivity is 1×10⁹ Ω·cm.

These plates are suitable for use with many types of connectors to suppress conducted EMI. The C dimension can be modified for specific applications. Single turn impedance tests are performed on the E4990A Impedance Analyzer. The package style is a connector-mounted suppression plate with no leads or termination style.
