875115957002 Capacitors

Aluminum - Polymer Capacitors are widely used in the fields of electronics, telecommunications and automotive applications. These capacitors are constructed with two or three layers of aluminum and polymer dielectrics, which are layered and soldered together to form a capacitor. The capacitors are constructed to provide high inrush current and low series resistance in smaller packages than conventional aluminum electrolytic capacitors.

The 875115957002 application field and working principle of aluminum-polymer capacitors takes into account three characteristics: voltage, capacitance, and temperature. When selecting a capacitor for use in any electronics, it is essential to understand how the combination of these three features will affect the performance of the device. Each component of an aluminum-polymer capacitor has a specified voltage and capacitance, and a temperature rating. The voltage determines the maximum voltage to be used and the capacitance determines the amount of energy that the capacitor can store. The temperature rating determines the range of temperatures that the capacitor can operate under.

The total capacitance of an aluminum-polymer capacitor is determined by the sum of the capacitance of each component in the capacitor. This is because the capacitance of each component is inversely proportional to its distance from the other components. This means that if a component is closer to the other components, its capacitance will increase. As the temperature ratings for each component are different, the total capacitance of a capacitor can also vary with the temperature.

Once the total capacitance of an aluminum-polymer capacitor is determined, the voltage can be calculated. The formula for calculating the voltage is: capacitance x temperature divided by the total capacitance for all components. The resultant voltage is referred to as the working voltage.

As capacitors are constructed with two or three layers, the working voltage can vary between the two layers. This is called the temperature coefficient. The temperature coefficient will typically be determined by testing the capacitor under extreme environmental conditions, such as subzero temperatures or high voltages. This allows the capacitor to be adjusted to meet the application requirements.

In order to ensure that the aluminum-polymer capacitor will remain in good working order throughout its life, it is important to keep the device in its intended operating environment. This may include controlling temperature and humidity levels as well as shielding the capacitor from electromagnetic interference.

The 875115957002 application field and working principle of aluminum-polymer capacitors make them an ideal choice for applications requiring a high capacitance and working voltage over a wide range of temperatures. Their lightweight and compact designs make them ideal for applications where weight and space are limited, such as those found in the automotive industry. They also offer increased efficacy due to their low series resistance, which reduces power loss and extend the life of the device.
