EFD transformer is a high frequency transformer designed for ultra-thin switching powersupply. lt has a flat ferrite core, its shape can meet the requirements of power transformerhigh power and ultra-thin volume requirements, the same can also meet the requirementsof switching power supply in temperature rise, but the requirements for PCB board will beimproved, and other performances are close to EE and EC Transformers. EFD transformercommonly used models have EFD15EFD20, EFD25, EFD30 and so on. The following tablelists the dimensions and output power of some products. The maximum output power varieswith the magnetic material characteristics and operating frequency. The data in the table arefor reference only. The test conditions are 1KHz/1v, voltage withstand AC2000v, insulationresistance:DC500V200MQ
