Tantalum capacitors are a special type of capacitors that are used in electronic circuits. They are highly efficient in terms of their electrical and mechanical performance and are available in a variety of shapes and sizes. The most common type of tantalum capacitor is the M39003/03-0413, which is used in many applications.The M39003/03-0413 is a surface mount device with a Low ESR (Equivalent Series Resistance) of only 0.95ohm. It has an operating temperature range of – 55°C to +85°C and a maximum voltage rating of 4V. This type of tantalum capacitor is used widely in industrial, automotive, medical, consumer and telecommunication applications.The device is constructed using a capacitor element which is made of an electrolyte solution sandwiched between two portions of anode material which have an extremely low electrical conductivity. The electrolyte solution is then sealed within an electro-chemically anodised Tantalum case. The anode material is usually a form of tantalum pentoxide.The chemical correctness of the material is critical in order to ensure the correct functioning of the device. The device also has a double layer oxide coating on its surface which helps to increase the capacitance of the capacitor element. This is known as the CV (Capacitance Voltage) curve.The working principle of the device is based on Faraday’s Law of Electromagnetic Induction. This states that when a capacitor is charged, it will store electrical energy which can later be discharged when required. This is achieved by passing an electric current through the capacitor, which causes the anode material to become positively charged. The positively charged anode material then attracts electrons from the cathode material which is negatively charged. When a potential source is connected to the device, the electrons flow from the negative electrode to the positive electrode, resulting in the transfer of electrical charge.The M39003/03-0413 is a highly reliable and efficient device which is used widely in many applications. It has a low impedance, a high capacitance and a high temperature tolerance which makes it ideal for use in high-performance applications. It is also an inexpensive device which makes it an attractive choice for many manufacturers.
