Medium and High Voltage Tantalum Powder-FTP

Category

Product features: FTP series flake tantalum powder is a kind of tantalum powder whose primary particles are flake. Compared with sodium-reduced tantalum powder, this tantalum powder has a larger Fisher particle size, a smaller specific surface area, and a simpler grain shape. It has good sintering resistance, high reliability, and high voltage resistance. It is especially suitable for making 20-63V medium and high voltage solid tantalum electrolytic capacitors with high reliability requirements.
