Recently, the business unit partners of Microelectronics have encountered such problems. Customers of some trading companies or distributors often want to know what is an EI square transformer and what ispin transformer. Since transformers are not a popular industry, the relevant knowledge is not familiar to everyone every day. Many customers also help their customers buy products on their behalf and they don't understand transformers. Today, I will share with you some tips to distinguish between EI square transformers and pin transformers.
In general, EI square transformers are low-frequency transformers, somepin transformerBelongs to the low frequency transformer, also some belong to the high frequency transformer, and the skeleton type transformer is mostly high frequency transformer. The appearance is also slightly different from the application.
Appearance: EI square transformer is mainly wire. Pin transformers have pins and no exposed wires.
Structurally: pin transformer is also called pcb transformer orpin transformerThe needle hits the bull. The process structure is to wind the copper wire on the transformer frame, and then weld the pins to the input and output windings of the transformer. The top pins are usually made of 0.5 mm-0.65mm copper-clad steel. Some pins are not all needle-shaped, but also sheet-shaped.
Application: Mostpin transformerPlug directly into the PCB board. Most EI square transformers are directly connected to the equipment through leadsInterface.
