Tantalum capacitors, are capacitors which make use of tantalum as the anode, as opposed to other materials such as aluminium and ceramic. This type of capacitor is very popular due to its excellent performance with a relatively compact footprint. The M39003/03-0312H is a Tantalum capacitor that is designed for use in high-frequency applications. It has a wide range of operating temperatures and is available in both axial and surface mount packages. The M39003/03-0312H has a Voltage Rating of 16V, a Capacitance of 470uF and a Maximum Dissipation of 2.7W.

The working principle of a Tantalum capacitor can be broken down into four stages: The anode, dielectric, cathode and electrolyte. In a solid tantalum capacitor, these four stages are constructed from the same material. The anode is made from a metal powder with a high resistance to oxidation and is mixed with a binder which helps to reduce its resistance. The mixture is then formed into a solid anode by thermal compression or extrusion. The dielectric material is formed by firing a mixture of tantalum oxide and/or titanium oxide. The cathode consists of manganese dioxide and the electrolyte is an aqueous solution of potassium, sodium and hydroxide.

When a voltage is applied across the capacitor, the anode is positively charged while the cathode is negatively charged. This creates an electric field between them which is strongest at the edges of the anode and cathode. This electric field causes electrons to move from the cathode to the anode, which in turn causes current to flow. The current causes a electric charge to build up in the dielectric layer of the capacitor, which is known as an Insulating Layer or dielectric breakdown. This process continues until the voltage across the capacitor reaches its rated value, at which point the current flow stops.

The M39003/03-0312H Capacitor is suitable for use in high-frequency applications such as radios, alarms, radar and telecommunication systems. Its low ESR (Equivalent Series Resistance) allows it to store more energy per unit of volume. Its low resistance also helps reduce heat loss in the device, making it well suited for long life applications. The M39003/03-0312H is also RoHS (Restriction of Hazardous Substances) compliant, meaning it does not contain any hazardous material which could harm the environment.

In summary, the M39003/03-0312H is a Tantalum capacitor that is designed for use in high-frequency applications. It has a wide range of operating temperatures, a Voltage Rating of 16V, a Capacitance of 470uF and a Maximum Dissipation of 2.7W and is RoHS compliant. Its low resistance helps reduce heat loss in the device, making it well suited for long life applications.
