Tantalum - Polymer Capacitors Tantalum - polymer capacitors are a type of electrochemical energy storage device commonly used in a wide range of applications and electronic equipment. These capacitors are typically composed of a solid electrolyte layer surrounded by two dielectrics – one ceramic and one tantalum – and a mixture of other materials such as talc, barium titanate, and or Bismuth oxide, depending on the type of capacitor.The T550B107K050AT4250 is a high performing, low-profile, conductive polymer aluminum solid tantalum capacitor. This small, robust capacitor is unique and comprises of a combination of two dielectrics – tantalum powder and aluminum oxide – a diaphragm, and a conductive polymer. The conductive polymer acts as the electrolyte material and provides excellent electrical performance and extremely low Effective Series Resistance (ESR). This capacitance is designed to fit in tight spaces and can be ordered in a range of capacitance values from 1µF to 680µF. It features RoHS compliance, low ESR, high frequency and high temperature rating, and a maximum working voltage of 50V.The main application for these T550B107K050AT4250 capacitors is to manage operations of circuit boards in various industry sectors like automotive, industrial, medical, telecommunication, aerospace, and defense. They can also be widely used in computing systems, power supplies, automotive power electronic systems, and communication networks.To understand how this T550B107K050AT4250 capacitor works, it is important to understand the working principles of a typical tantalum-polymer capacitor. How a capacitor works can be explained using the simplified figure below.When a voltage is applied across a tantalum-polymer capacitor, electric charges accumulate on the two dielectrics, and these charges create a potential (voltage) difference between the two dielectrics. This potential difference is the capacitor’s Voltage Withstand Level (V WL). The magnitude of this voltage can be adjusted by changing the thickness of the diaphragm – the part of the capacitor which separates the two dielectrics – as well as other components like the electrolyte material or the type of tantalum material used. As such, different types of tantalum-polymer capacitors will have different V WL values.The current of the device is controlled by the thickness of the diaphragm and the resistance of the electrolyte material. The resistance of the electrolyte material limits the amount of current that can flow through the capacitor and its performance. The ESR of the device is determined by the type of electrolyte material and its temperature-dependent properties.In conclusion, the T550B107K050AT4250 capacitor is a low-profile, conductive aluminum solid tantalum capacitor specially designed for use in tight spaces. It is commonly used in different industry sectors for managing operations of circuit boards and can provide excellent electrical performance due to its combination of two dielectrics and a conductive polymer. Its working principle is based on the accumulation of electric charge between two dielectrics and the regulation of current by the diaphragm and electrolyte material.
