Aluminum - Polymer Capacitors are designed to store and release energy in circuits that experience frequent changes in voltages, such as in inverters, switching regulators, and other applications that are subject to frequent voltage changes. They are ideal for operating in environments with limited space and high temperature conditions. This type of capacitor is composed of an aluminum layer, a polymer layer and a glass or ceramic substrate. The aluminum and polymer layers form a dielectric, commonly referred to as tanatalum, which is sandwiched between the metal and the polymer, providing energy storage and release capabilities.The 875105244012 Aluminum - Polymer Capacitor is a surface mount tanatalum capacitor device with a capacitance range of up to 4700μF, suitable for applications in the 0.5 - 50 V range. This capacitor is significantly smaller than standard electrolytic and tantalum counterparts, making it ideal for confined spaces and is suitable for temperature ranges from -55 to 85 °C. This capacitor offers high conductivity, low equivalent series resistance (ESR) and a long life span, and is offered in a wide range of capacitance ranges.When an electrical voltage is applied to the 875105244012 Aluminum - Polymer Capacitor, electrons are drawn to the positive end of the capacitor, while the negatively charged ions are pushed to the outside to the negative end. This potential difference creates an electric field which is responsible for storing and releasing the energy within the capacitor. As the electrical voltage changes, the electric field adjusts accordingly, changing the charge within the capacitor. This fluctuation of charge sets up an alternating current flow in the circuit, allowing energy to be stored and subsequently released as needed for the applications.

The 875105244012 Aluminum - Polymer Capacitor also features several components that contribute to its superior performance. The device is composed of a solid aluminum foil anode on which the polymer dielectric is deposited. The device also features a bottom anode film which are typically formed from copper, copper-coated steel, or anode material film in order to reduce contact resistance. The top of the device also includes an epoxy molding compound which encloses the top edge of the aluminum foil and helps improve insulation. Furthermore, the capacitor utilizes a wet-proofing process to protect the dielectric and anode layers from external liquids.

The 875105244012 Aluminum - Polymer Capacitor is commonly used in a wide range of applications, such as power supplies, switching power supplies, sound amplifiers and instrumentation. This device is particularly ideal for applications where physical space is limited, due to its miniature size, and is also suitable for operation in harsh conditions. Additionally, its low ESR, high temperature stability and long service life reduce maintenance costs, making the device a cost effective option for a variety of applications.
