Electromagnetic Power Choke Coil Inductor Enameled Wire
Electromagnetic Enameled Wire Toroidal Choke Coil
High-frequency transformers are power transformers whose working frequency exceeds the intermediate frequency (10kHz). They are mainly used as high-frequency switching power supply transformers in high-frequency switching power supplies. They are also used as high-frequency inverters in high-frequency inverter power supplies and high-frequency inverter welding machines. Change the power transformer. According to the working frequency, it can be divided into several grades: 10kHz-50kHz, 50kHz-100kHz, 100kHz~500kHz, 500kHz~1MHz, and above 10MHz.
Common mode Choke, also known as Common mode Choke, is commonly used to filter Common mode EMI signals in switching power supplies of computers.In board card design, common-mode inductor also plays the role of EMI filter, which is used to suppress the electromagnetic wave emitted by high-speed signal line.
