Aluminum electrolytic capacitors are a type of capacitor that uses an electrolyte to achieve a larger capacitance value per unit volume than other ones. The 16PK470MEFC8X11.5 is a capacitor of this type that is mainly used in electronic devices. This article will discuss the application field and working principle of the 16PK470MEFC8X11.5.

The 16PK470MEFC8X11.5 is mainly used in either a bypass application or a decoupling application. As a bypass capacitor, this part is used to short a high-frequency noise signal while allowing a low-frequency signal to pass through. This would be employed in cases where certain high-frequency signals need to be blocked from entering an application circuit. In decoupling applications, the 16PK470MEFC8X11.5 is used to absorb energy and thus protect the components connected before it from any unexpected indirect current. It is typically used in applications like: audio amplifiers, video amplifiers, television receivers, and radio receivers.

The 16PK470MEFC8X11.5 operates using an electrolytic capacitor principle. This concept involves using a conductive electrolyte, usually in form of an acidic solution, to form the dielectric layer on the capacitor. It consists of a positive electrode, which is typically made of aluminum and contains a porous layer, and a negative electrode made of a metal with a higher electron affinity opposite the electrolyte. This creates a space charge layer between the electrodes. When a voltage is applied across the two electrodes, an electric double layer is generated, which will contribute to the overall capacitance.

The 16PK470MEFC8X11.5 has a number of advantages. It has a high capacitance to volume ratio, which allows it to occupy less space in an application circuit while providing a sufficient capacitance value. In addition, it can be operated at relatively high frequencies, with its self-resonant frequency reaching up to mid-MHz ranges. Moreover, the 16PK470MEFC8X11.5 can be used as a filter in power supplies thanks to its excellent characteristics for ripple current and noise absorption. Furthermore, it is highly resistant to external shocks and vibration and can withstand temperatures up to -40°C to 85°C.

In summary, the 16PK470MEFC8X11.5 is an aluminum electrolytic capacitor mainly used in a bypass or decoupling applications. It operates using the electrolytic capacitor principle, whereby a voltage is applied across two electrodes to form an electric double layer, allowing it to generate a sizeable capacitance value. Furthermore, the 16PK470MEFC8X11.5 has a number of advantages, such as a high capacitance to volume ratio, operating frequency and ability to be used as a filter in power supplies.
