Toroidal Choke Coils Common mode chokes are used because many electrical devices may be connected to the same power lines (or power supply lines), substantial electrical noise can exist on these lines. Switching mode power supplies can generate a lot of high frequency noise which can travel over the power lines and interfere with the operation of computers and other electronic devices connected to the power lines. A common mode choke may be used to reduce a type of electrical noise known as common mode noise. Electro-magnetic interference (E.M.I.) in the circuit's environment is one source of electrical noise. E.M.I. induces or couples unwanted electrical signals into the circuit. It is desirable to filter out the unwanted noise signals without significantly affecting the desired signal. We have various type of items. Usually, Choke Coils, Line Filter are made to order. DIMESION Vertical Type (Core Size) Horizontal Type (Core Size) Applications Choke Coil for SMPS EMI Noise filter Low pass filter for Digital Amp PFC filter for PDP TV DC Reactor for PC Power transformer High Pass filter TV or Audio equipment, Telecommunication devices, Electronic contral board, RF Filters, Other Noise Filter TYPE V - TYPE Standard Base H - TYPE Standard Base Line Filter Line Filter is compact in size and large Inductance and have excellent electromagnetic noise suppression properties. TOROIDAL TYPE LINE FILTER Applications Choke Coil for SMPS EMI Noise filter Low pass filter for Digital Amp PFC filter for PDP TV DC Reactor for PC Power transformer High Pass filter TV or Audio equipment, Telecommunication devices, Electronic contral board, RF Filters, Other Noise Filter CORE ELECTRONICS makes Chokes Coils and LINE Filter in a wide variety of shapes and sizes. 25 26
