Working Principle

The main components of a tantalum capacitor are the two terminals, an anode, and a cathode. The anode is typically made of conductive tantalum powder with a manganese dioxide electrolyte, while the cathode is typically made of metallic oxide particles. When a voltage is applied to the terminals, an electric field is created in between them, which causes the anode and cathode to become polarized and store a charge. This charge can then be used as a power source for the capacitor’s applications.

In the M39003/03-4020/HSD, the hermetically sealed case provides additional protection from environmental elements, such as moisture, dust, and corrosion. This allows the capacitor to function better and for longer, which makes it better suited for a wide range of applications.
