Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are one of the most important components, broadly used in various kinds of electronics products and digital devices. Not only restricted to the electronics applications, aluminum electrolytic capacitors also have been applied to many fields such as automotives, industrial control systems and aircrafts as well. Here we will focus on the description of the application field and working principle of UKW1C472MHD aluminum electrolytic capacitor.UKW1C472MHD aluminum electrolytic capacitors are mainly used in high frequency and filtering applications. Comparing with film capacitors, they are characterized with much higher capacitance with same volumetric size and also better mechanical strength to resist high voltage shocks and vibrations without any direct damage. Generally, this type of capacitors are made up of an anode aluminum foil, a separator soaked with an electrolyte, and a spiral-wrapped cathode foil. Those are compounded in the form of porous blocks. The working principle of UKW1C472MHD aluminum electrolytic capacitor is based on the fact that the anode aluminum foil is able to form a passive film over its surface through oxidation. This allows a large capacitance within a very small size. In this case, electrons can travel through the film instead of the electrolyte itself, which creates a bidirectional electrical field along the separator-cathode foil direction. Thus the capacitive effect happens.Apart from the advantages of high capacitance and high voltage shock resistance, UKW1C472MHD aluminum electrolytic capacitors also have several other useful features, such as low cost, low ESR and higher power handling. These could make them the ideal component for both the high-frequency and high-current electronic circuits. Normally, they can be expected to meet an operating temperature of -40°C to 85°C. Certainly, like most of the electrical components, the UKW1C472MHD aluminum electrolytic capacitors also need to pay attention to the follows: their life expectancy is determined by the ESR, ripple current and operating temperature; the temperature should not exceed their rated operating temperature as it will significantly shorten the capacitor life; and proper mounting is necessary as well.In conclusion, UKW1C472MHD aluminum electrolytic capacitor is an ideal component for high frequency, high current and filtering applications. It has a wide operating temperature range and characterizes with low ESR, good power handling and long life expectancy. Proper mounting and operating temperature control are essential to ensure the efficiency and safety of the application.
