126 WIDE BAND CHOKE SERIES WB FEATURES DIMENSIONS IN INCHES 45o - Inexpensive for broad use - These wide band chokes can be customized into single or o o o 0.236 0.012 0.081 multi-turn windings o o o - For the most demanding EMI filtering, the 3 turns winding can provide lossy impedance close to 1000 ohms Hole dia 0.031 0.004 (6X) - Since the high frequency performance of wound magnetics is compromised by the inter-winding capacitance that exists between multiple conductor turns, the 6 hole bead with one or two turns 3 turns provides improved performance for applications above 100 MHz - With 2 windings of 1.5 turns, the 6 hole bead provides a typical common mode choke. With equal and opposite current flowing through the bead, zero net bias is established and maximum impedance is realized from the bead 2.5 turns 0.394 0.020 PHYSICAL CHARACTERISTICS - Wire specifications - Packaging 24 AWG tinned copper wire 1000 pieces per plastic bag 2 X 1.5 turns SPECIFICATIONS Part Number Number of Turns Z @ 100 MHz ( ) Winding configuration Lead length ( max ) WB2-1.0T WB2-1.5T WB2-2.0T WB2-2.5T WB2-2X1.5T 1 turn 1.5 turns 2 turns 2.5 turns 1.5 turns with 2 windings 200 470 600 725 450 Radial lead Axial lead Radial lead Axial lead Axial lead 0.50" 1.50" 0.50" 1.50" 1.50" WB2-3.0T 3 turns 750 Radial lead 0.50" WB4-1.0T WB4-1.5T WB4-2.0T WB4-2.5T WB4-2X1.5T 1 turn 1.5 turns 2 turns 2.5 turns 1.5 turns with 2 windings 150 400 525 650 450 Radial lead Axial lead Radial lead Axial lead Axial lead 0.50" 1.50" 0.50" 1.50" 1.50" WB4-3.0T 3 turns 690 Radial lead 0.50" Associated Components Technology / Phone 800-234-2645 / Fax 714-265-4810 / Website http://www.act1.com
