Tantalum Capacitors

Tantalum capacitors are widely used in electronics due to their high-frequency responses, low-loss characteristics and long shelf life. As part of the capacitor family, tantalum capacitors offer a significant increase in performance over other types of capacitors. The T491A475K016AH is a type of tantalum capacitor that is used in a variety of applications.The T491A475K016AH is a polarized capacitor, meaning that it takes a positive and negative voltage to be connected correctly. The T491A475K016AH applies an anode on the outer casing and a cathode located on the interior. Connecting the anode and cathode in the wrong order can cause damage to the capacitor. The voltage range of the T491A475K016AH is 16V and the capacitance range is 4.7uF resulting in a maximum current rating of 0.25A.The T491A475K016AH is constructed with an electrolyte, typically tantalum oxide, and two metal plates. This construction offers an extremely stable capacitor, with a shelf life that can last for decades. An internal oxide layer forms over the plates, forming the dielectric. The eroding of the oxide layer is the cause of leakage current, resulting in a loss in capacitance.The T491A475K016AH is most commonly used in filter and bypass capacitors. Filter capacitors are used to filter or reduce AC component signals while Bypass capacitors are often used as signal bypassing to improve signal quality. This makes the T491A475K016AH ideal for signal or power conditioning in circuits.The T491A475K016AH can be used in many applications where high capacitance values, long shelf life and high surge current ratings are needed. Such applications include power conditioning, signal filtering, audio signal conditioning and oscillator circuits. The T491A475K016AH is also used in regulator circuits and power supplies to provide high capacitance.The advantages of using periodic Electrolytic capacitor include: their high-frequency response, long shelf life, stability, and low-loss characteristics. They also have a low total equivalent series resistance (ESR) for a given capacitance, making them ideal for power conditioning. Additionally, Smaller size capacitors on the market with higher capacitance values and higher current ratings, making them ideal for a variety of applications.Due to their unique construction, the T491A475K016AH is a rugged capacitor with a high current rating and long shelf life. The T491A475K016AH can be used in many different circuits due to its high capacitance and current ratings and excellent frequency response. This makes the T491A475K016AH ideal for power and signal conditioning, audio signal conditioning, oscillator circuits and other applications.
