5 times more than the capacitor, but also pay attention to the positive and negative poles can not be connected to the reverse, especially the power supply part of the electrolytic capacitors should pay more attention to these two points, otherwise the capacitor may occur burst events. In addition, there is a brand of capacitors, different brands of resistance is just not the same error value, but different brands of capacitors is the life and quality of the different, such as a variety of losses and insulation resistance and temperature coefficients of the different. The following author will introduce a few good brands to you: PHILIPS Philips, RubyconBLACK GATE black gold steel, Rubycon Ruby, ELNA, ROE, SOLEN, Nichicon, DECON, WIMA this product is very expensive capacitors above the capacity of 1μF, RIFA, ERO, if you really do not recognize it. You really do not recognize the words you just remember that all capacitors on the C, D two letters all prefix capacitors do not buy, such capacitors are not the world's leading manufacturers, and even some capacitors used in computer boards and cards may also cause a bad influence. These capacitors can only be used to capacitance performance requirements are not very high in the product for example, to 4 dollars a radio, its capacity and some other performance indicators on the error is very large, even if the new factory products can ensure that 4 years or so can have a better performance, so it can not be loaded into the computer accessories.

While SRAM is said to be static, both SRAM and DRAM are volatile memories because they need a constant DC power source to maintain their states. If the power source is disconnected, the charges leave and the potentials drop to zero, erasing the information stored in all the cells. This is why the hard drive serves its special function of holding information even when the power is gone.

Silver mica capacitors are widely used in electronic circuits due to their stability, high precision, and reliability. They employ a thin sheet of mica as the dielectric material, which is sandwiched between two metal electrodes, typically made of silver. The silver electrodes are connected to the external leads of the capacitor. One of the key advantages of the silver mica capacitor is its exceptional temperature stability. It exhibits minimal variation in capacitance over a wide range of operating temperatures, making it suitable for applications that require precise and consistent performance.

By carefully evaluating these factors and understanding the requirements of your specific application, you can select a capacitor that meets your performance, reliability, and budgetary needs. Working closely with component suppliers or consulting engineering resources can provide valuable insights and guidance to ensure an optimal capacitor selection for your project.

Any type of similar value simple capacitor can he used in place of same value simple capacitor. In some capacitors air is used as dielectric material. Such capacitors are known as air capacitors. Some important capacitors and their features are as follows: Mica is such a material which is available in a thin layer in the nature. Its dielectric constant is very high. Especially for high frequency, it works as a good insulator even on high temperature.

A paper soaked in wax or oil is used as the dielectric in the paper capacitor . In between tin foils that serve as capacitor plates . This is shown in figure (3a) . In order to increase the capacitance to a large extent , waxed paper and strips of metal foils are arranged alternatively as shown in figure (3b) .

There is very low frequency loss in it, because of these silient features it is used as dielectric material in the capacitors. These type of capacitors are known as mica capacitor. Since winding of mica is not possible therefore mica capacitor are always flat in shape. These capacitors are used where more accuracy and high dielectric constant is needed. Mica capacitors are of various types.

Capacitors are extensively used for coupling and decoupling purposes in electronic circuits. In coupling applications, capacitors enable the transmission of AC signals while blocking DC components. They are used to connect different stages of amplifiers, allowing the AC signal to pass from one stage to another, while maintaining DC isolation. Capacitors also play a crucial role in decoupling, where they provide a stable source of local power to sensitive components. By placing capacitors near integrated circuits or microcontrollers, they help to smooth out voltage fluctuations caused by sudden changes in current demand. Choosing the right capacitor involves considering multiple criteria, such as capacitance, voltage rating, temperature and environmental considerations, size and package type, frequency response, and cost.
