Speaking of resistors, I think many friends are not strangers. We learned it when we were in junior high school. It is actually a component used to limit the flow. In this case, you are a little confused. What does it have to do with the epoxy plate? Why is the good material for the resistor. Don’t worry, I think you will understand after you finish reading this article.
There are many occasions where resistors are used, if in some chemical and pharmaceutical establishments. It must be corroded in varying degrees. Moreover, the air pollution is very serious nowadays. Many corrosive ions in the atmosphere also have certain corrosion effect on the boards. The epoxy board has excellent corrosion resistance and greatly retard the aging of the boards.
Nowadays, many resistors are used for cameras and medical electronic products. With the lightening of electronic products, the requirements for plates are becoming increasingly demanding. The density of epoxy panels is 1.70-1.90g/cm?, which meets the needs of modern electronic products.
High temperature resistance
Resistors can be said to work day and night, naturally will grow as time goes on, and generate heat. The high temperature resistance of the epoxy plate can reach B level, the temperature is about 155 degrees, so we don’t have to worry about the heat of the resistor because of the long working of the resistor, which affects the plate, the cracks, the dark color and so on.
For the insulation of electronic products is especially important, the breakdown voltage of the epoxy plate is as high as: the parallel layer breakdown voltage (in the transformer oil of 90 + 2 c): more than 40KV, even if the country’s electricity consumption is rising continuously. But to achieve its breakdown voltage, it is unprecedented.
No need for regular maintenance
It has good performance and does not require regular testing. This greatly saves the manpower and material resources. It saves money. It’s good to say that it has a permanent effect on resistors.
Bright colors and many varieties
Its color is yellow, water green, white, black and so on. There are more choices for people. Bright colors not only make the whole resistor look vibrant, but also greatly save the time people look for when testing.
I think we all know why epoxy plates are good materials for resistor insulation. The above views belong to my personal understanding. Where is there a place that is not clear or there is a wrong place? You are welcome to correct them.
