Cautions of Transformer
3.1 Application scenarios-widely used in various high-end, high-precision small instruments and meters such as: electric meters, meters, controllers, ultra-thin switching power supplies, electronic circuits, high-power chargers, etc., more application scenarios are waiting for your suggestions.
3.2 Types-There are many types of transformers. According to the working frequency, they can be divided into low frequency transformers, intermediate frequency transformers, and high frequency transformers. According to the pin installation method, there are pin transformers (also called PCB transformers) and potting transformers (high, Low voltage windings are all poured with epoxy resin in vacuum and cured, etc. Please choose the appropriate category and related parameters according to the application scenario.
3.3 Material-Ferrite core is used, which can meet the requirements of ultra-thin volume and temperature rise. It has high permeability, high magnetic saturation density, and low core loss. For specific materials, please refer to the technical leaflet provided by our company or The sales leaflet shall prevail.
