特种宇航级云母电容器用真空浸渍树脂研究

he compelling need to high reliability, coupled with a desire to application in the spacecraft, is the principal reasons why mica capacitors have become capacitors of first resort, especially for filter capacitors. The electron components in the spacecraft have to face the challenge of harsh space environment, they can not be applicable for replacement and maintenance, quickly and efficiently, so that the capacitors need to upgrade fitting for the space flight standards. It is well known that there is few scientific research on the high-end mica capacitors. In this paper, a kind of imported aerospace mica capacitor was analyzed and especially the chemical components of its VPI impregnating resin were studied. It was very useful that the related materials can be obtained by Chinese independent research and development in the future.
