Polyurethane has been used in China for a period of time, but due to its high hardness, inconvenient maintenance, and the price reduction of silicone rubber, the cost performance of polyurethane is not high.

At the same time, the design of the high-frequency switching transformer winding in the module switching power supply is also very important. The winding of the high-frequency switching transformer not only affects the copper loss, but also relates to the coupling between the high-frequency switching transformer windings, and also affects the iron loss of the high-frequency switching transformer. Influence, the design and manufacture of high-frequency switching transformers have a great impact on the performance of the module switching power supply

Special attention should be paid to the thermal conductivity related to thermal design. Generally, a thermal conductivity of 0.4W/M•K is defined as high thermal conductivity, and greater than 1 is defined as extremely high thermal conductivity.
