T491B225M035AT4860

T491B225M035AT4860 is a type of tantalum capacitor. A tantalum capacitor is an electrolytic capacitor, a passive electronic component, that uses the metal tantalum as an electrolyte. It consists of two electrodes, an anode and a cathode, and a solid or gel electrolytic dielectric material that separates them. It is usually a polarized capacitor, meaning that it has a positive and negative terminal, and behaves oppositely depending on which way the voltage is applied. Tantalum capacitors are widely used for their high volumetric efficiency, low ESR, and lower distortion due to low dielectric absorption.

The T491B225M035AT4860 is a bi-polarized, surface-mount, convex, encapsulated, solid tantalum-based electrolytic capacitor commonly used in many electronic applications. It has a capacitance value of 22 uF and an operating temperature range of -55°C to +125°C. This capacitor is made with a Kynar® (PVDF) dielectric material and is suitable for both high temperature, high frequency, and low temperature applications. The positive electrode is tin-plated niobium, while the negative electrode is manganese dioxide. It is highly resistant to oxidation and corrosion, even in humid or aggressive atmospheres. It is also very reliable, with a life expectancy of up to 4 billion cycles at ambient temperatures.

Tantalum capacitors work by storing a static electric charge and releasing it when an electric field is applied; this charge is stored as a reverse-biased electric field between the two electrodes. The dielectric material acts as a barrier and prevents the stored charge from leaking. The dielectric material is typically insulated from the anode and cathode by a thin glass-like substance called a dielectric layer; this insulating layer is essential for the capacitor to store and release the charge. When a voltage is applied across the two electrodes, electrons will flow from the anode to the cathode, creating a current. As the current builds, electricity is stored in the capacitor, creating an electric field that opposes the incoming voltage, eventually preventing the current from flowing any further. When the voltage is removed, the reverse biased electric field holds the charge and prevents it from dissipating.

The T491B225M035AT4860 is used in a variety of applications such as transportation, automotive, industrial, aerospace, power supplies and renewable energy. It is suitable for use in a wide range of applications where high current pulses, high voltages, and rapid charge/discharge cycle times are required. In automotive applications, it is often used to reduce or eliminate noise in the electrical system. In renewable energy applications, it is used to store energy from solar and wind power systems. It is also used in power supplies to provide stable, regulated power, and in industrial applications to reduce power loss due to inductive loads.

T491B225M035AT4860 is a highly reliable, long-lasting, and reliable capacitor with many application. It is a versatile part, suitable for both high temperature and low temperature applications, and is capable of storing and releasing a significant amount of energy in a short amount of time. It is a valuable component for many applications and can be used to improve the reliability and performance of many electronic systems.
