Capacitor Grade Tantalum Powder (20V-60V) Description
Tantalum has twice the density of steel and it is highly ductile. It has the fourth-highest melting point of all metals and is able to form extremely thin and protective oxide layers for high-quality capacitors. Our powder also has a high surface area and great handling and flow properties.
