Tantalum Capacitors

Tantalum capacitors are electrical components that are used to store energy in an electrical form. They are made of a mixture of tantalum metal and a dielectric material. The most common dielectric material used are polymers and there are various types available. The model 150D476X0020R2G is a type of tantalum capacitor. The part number is made up of the capacitance, tolerance, voltage, dielectric, form factor and case size. This model is a 47uF (micro Farad) 23V capacitor that uses an organic polymer as its dielectric. The form factor of this capacitor is an axial leaded disk with a 20mm diameter. Tantalum capacitors have many uses. They are often used as the main energy storage elements in systems that require a small and efficient storage device. This includes applications such as automotive electronics, smartphones, PDAs and medical devices. They are also used in switching power supplies, display and audio systems, and in clock oscillators. The working principle of a tantalum capacitor is similar to that of other capacitors; it stores energy in the form of electrical charge. The capacitor consists of two parallel plates which are separated by a dielectric material. When an electric field is applied to the capacitor, the dielectric material stores an electric charge which causes a change in the capacitance. The capacitance, or the amount of energy stored in the capacitor, can be changed by changing the dielectric material, the size of the plates, and the distance between the plates.The most common type of tantalum capacitor is the molded radial leaded type; these are the ones found in small electronics and consumer devices. Its construction is composed of a cylindrical tantalum anode, a polymer dielectric material and a tantalum cathode. The electrodes are connected to an internal lead frame, and the entire device is enclosed in a molded case. To ensure reliable operation, the pressure applied to the molded case is designed to keep all parts in place. In consumer electronics, these capacitors are usually mounted on a Printed Circuit Board through soldering. To reduce their overall size, manufacturers often use Surface Mount Technology to bond them directly onto the PCB.Tantalum capacitors offer several advantages when used in electronic applications. They have a relatively small size and low cost compared to other types of capacitors. Additionally, their temperature coefficients are low, so they can withstand temperatures up to 200°C. Furthermore, they have a great stability and a long operational life, which makes them suitable for applications such as automotive electronics. The 150D476X0020R2G tantalum capacitor is specifically designed for higher temperatures and has a tolerance of +-20%. This makes it a good choice for applications such as automotive electronics, as it can withstand temperatures up to 125°C.Overall, the 150D476X0020R2G is an efficient and reliable tantalum capacitor. It has a small size, low cost, and a long life, making it suitable for a wide range of applications. Furthermore, its temperature range and tolerance make it suitable for use in automotive electronics.
