Tantalum capacitors are an important type of capacitor. Originally used in military equipment and applications where high reliability was required, they are now widely used in a variety of different applications.The T491B155M035AT is a type of tantalum capacitor. It is an axial-type electrolytic capacitor, with a radial leaded version also available. It has a voltage rating of 35 volts and is polarized with a negative lead. Its capacitance is 155μF, with a tolerance of ±20%.The T491B155M035AT is commonly used in automotive and electronic applications like automotive amplifiers, radio surround sound systems, and audio/visual equipment in general. It is also used in power supplies, where it can help to filter out noise, making it ideal for situations where reliability and accuracy are of the utmost importance.The working principle of an electrolytic capacitor, like the T491B155M035AT, is based on the ability of a chemical reaction to generate electrical charges. This chemical reaction is initiated when a voltage is applied across the leads and charges are then stored in an electrolyte solution which is between the two dielectric layers of the capacitor.The two dielectric layers form a barrier between the two electrodes, which separate the two electrical charges. When a voltage is applied, the charges separate and build up potential energy which helps to form an electric field. The voltage applied across the two leads will determine the capacity of the capacitor, which is essentially the amount of potential energy that can be stored.The T491B155M035AT is a very reliable capacitor and is well suited to most automotive and electrical applications. It is a robust, reliable, and cost effective solution and is known for its exceptional durability and accuracy, making it a popular choice for a variety of industry applications.
