50HZ or 60HZ), power transformers, and some audio transformers are also EI, such as audio.

Classification of silicon steel ei transformer laminate

Silicon steel ei transformer lamination is classified according to installation method

It is divided into pin type and lead type riding type. The pin type is soldered on the circuit board. The lead type is external lead wire. Most of them are iron shells on the outside, and the iron shell has mounting holes, which can be screwed.

Silicon steel ei transformer lamination according to core size classification

EI transformers are categorized by size, and the general category is classified according to the length of the silicon steel sheet. For example, commonly used EI-19, EI-28, EI-35, EI-41, EI-48, EI-57, EI-66, EI-76.2, EI-86, EI-96, EI-114 and so on. Among them, 28, 35, and 41 refer to the length of the silicon steel sheet.

The detailed classification should also consider the total stack thickness of silicon steel sheets. Some transformers are marked with EI-48*20. This 20 means that the total stack thickness of silicon steel sheets is 20mm, so this transformer is EI-48, subdivided EI-48*20.

In some places, it is classified according to the width of the silicon steel sheet, and the hatch is the part protruding in the middle of the E piece.
