The material used in the ydk-700v capacitor developed by capsun and tdk is 820v, which has been used in Japanese capsun group audio system. This is of great epoch-making significance, which means that the 537v rectified 380v will no longer need 2 400v de-series. The future performance of aluminum electrolytic capacitors will be further developed with the development of technology. The normal capacitance volume of 700v100uf is usually in the range of $22 or $22 for 35*80-100mm or 50*80-96mm.
