The 2944666661 is a wound ferrite bead manufactured by Fair-Rite Products, designed for EMI suppression and signal conditioning in electronic circuits. This component features a NiZn material composition with 1½ turns of 24 AWG oxygen-free high conductivity copper wire with 100% matte tin plating over nickel undercoating, wound through a six-hole ferrite core. The bead exhibits typical impedance values ranging from 42 O at 1 MHz to 555 O at 200 MHz, providing effective attenuation across a wide frequency spectrum. With a compact form factor (6 mm × 10 mm core dimensions) and operating temperature range of -55°C to 125°C, this wound bead is ideal for high-frequency filtering, noise reduction in power supplies, and signal integrity applications in telecommunications, computing, and industrial electronics.
