EI33 EE type high frequency power transformer

High-frequency transformers are power transformers whose working frequency exceeds intermediate frequency (10KHz). They are mainly used as high-frequency switching power transformers in high-frequency switching power supplies, and also used as high-frequency inverter power transformers in high-frequency inverter power supplies and welding machines. According to the working frequency, it can be divided into several grades: 10KHZ-50KHZ, 50KHZ-100KHZ, 100KHZ ~ 500KHZ, 500KHZ ~ 1MHz, and more than 10MHZ.
