The 2944666631 is a wound ferrite bead manufactured by Fair-Rite Products, designed for electromagnetic interference (EMI) suppression and signal conditioning in electronic circuits. This component features a NiZn material grade with oxygen-free high conductivity copper wire wound with 100% matte tin plating over a nickel undercoating, providing excellent electrical performance and corrosion resistance. The bead exhibits typical impedance values ranging from 131 O at 1 MHz to 1200 O at 100 MHz, with dimensions of 6 mm (A) × 0.75 mm (B) × 10 mm (C), and is wound with 3 turns of 24 AWG wire at 38.0 ± 3.0 mm length. Operating and storage temperatures range from -55°C to 125°C, ensuring reliable performance across diverse environmental conditions. This wound bead is commonly used in high-frequency filtering, power supply noise reduction, and signal integrity applications where compact form factor and predictable impedance characteristics are essential.
