Wide band choke we are leading manufacture and supply SMD power inductor?Bpower transformer?Bhigh & low frequency transformer?Bfiltered modular Jacks?Bcommunication transformer?Bcoil etc the coil including :1)Common mode choke ,2)wide band choke,3) PFC(Power factor choke) The wide band choke mainly work as a filter to eliminate E.M.I Problems for large current. 1)Feature The chokes consist of rod-type bodies with six or eight axial holes through which wire is threaded to from a 0.5, 1.0, 1.5*2, 2.5, 3 or 3.5 turns coil. 2) Application 1)R6H R8H Type Cores are used for Wide Band Choke. The impedance is substantially resistive and constant. 2)Used in PC boards to filter the EMI from the outsides computer disk drivers and communication equipments, etc.
