In order to improve the transient response, it is recommended to use AVX tantalum capacitor as output capacitor, this capacitor is a metal tantalum as a positive electrode, dilute sulfuric acid and other liquid as the negative, tantalum surface oxide film made of medium. The main advantages of high insulation resistance, wide frequency response, low leakage current, good temperature characteristics (operating temperature range of -55 ~ +125 ℃), small size, large capacity, stable performance, long life, can be widely used Military, computer, mobile phone, power controller and other high-end technology.
