The 2661000701 is a ferrite EMI suppression bead manufactured by Fair-Rite Products, designed to suppress electromagnetic interference in signal lines and power circuits. This 61 material grade bead features typical impedance values of 134 O at 100 MHz, 174 O at 250 MHz, 206 O at 500 MHz, and 230 O at 1000 MHz, with a DC bias field of 2 Oe per ampere-turn. The bead has outer diameter (A) of 3.5 mm, inner diameter (B) of 1.3 mm, and length (C) of 12.7 mm, with a weight of 0.38 g, and the length dimension can be modified to suit specific applications. These beads are ideal for use in high-frequency signal conditioning, power supply filtering, and general EMI suppression applications where guaranteed minimum impedance specifications are required.
