Aluminum electrolytic capacitors (AECs) are similar in construction to conventional wet tantalum capacitors, but the electrolyte for these applications is aluminum instead of manganese dioxide. Aluminum electrolytic capacitors are used for a wide range of electrical and electronic applications from high voltage applications, to low voltage applications such as control and power supplies. The AECs construction varies from manufacturer to manufacturer.
The UKA1A101MDD is a series of radially leaded aluminum electrolytic capacitors designed specifically for motor control applications. These AECs are designed with a high withstand voltage rating and havae superior ripple current capabilities. The UKA1A101MDD is manufactured using a dielectric material, tantalum pentoxide and an electrolyte composed of at least 35% of aluminum. This combination provides the highest operating temperature ratings, including the ability to withstand temperatures up to 250°C.
The larger size of the 2.5mm and 5mm lead spacings provides a larger and more robust contact for increased connection strength. The unique shape and design makes it easier to mount and remove the AECs from boards. Furthermore, the sturdy wall construction provides protection from mechanical shock and vibration. The internal components of the capacitor are enclosed in a robust plastic housing, which helps to protect the capacitance from environmental influences.
The working principle of the UKA1A101MDD is based on the fact that a capacitor stores electrical energy in the form of an electric field between two parallel surfaces. The dielectric, or the insulating material, allows electrons to continue to flow through the capacitor, thus creating the electric field. The UKA1A101MDD electrolytic capacitor is designed to provide superior capacitance values and stability in conditions of high voltages and temperatures. The internal dielectric layer provides protection from external influences and also helps to maintain frequency stability. The electrolyte provides additional protection from electrical stress and maintains a constant capacitance value during operation.
The UKA1A101MDD aluminum electrolytic capacitors are an ideal choice for applications requiring high withstand voltages, capacity and stability. They can be used in a wide range of motor control applications, including power supplies, motor starters, industrial controllers and other high voltage applications. Their exceptional temperature range, frequency stability and reliability, coupled with their robust construction, makes them an ideal choice for the toughest applications.
