Aluminum - Polymer Capacitors, or often referred to as Al-Polymer capacitors, are an essential component of electrical power, energy storage, and pulse operation circuits. The 2.5SW470M2.9X7.3 is an aluminum-polymer capacitor, which is a class of high-performance and high-density, polarized capacitor. It is usually most commonly used in high-current applications such as DC-DC converters, resonant converters, and UPS systems.
The conventional aluminum electrolytic capacitors, the wafer-style aluminum-polymer capacitors are far more efficient and reliable in terms of current capability and lifetime. What makes this capacitor so popular is its ability to operate at volatility of up to 35V, hence, it can handle larger currents with better results and lesser heat emission. Additionally, the 2.5SW470M2.9X7.3 capacitors possess a unique solid-state electrochemical construction that further helps in miniaturization, and provides considerable output power due to their extremely low internal resistance values.
The structure of the 2.5SW470M2.9X7.3 aluminum-polymer capacitor consists of an anodic aluminum wafer and multiple terminal leads. This combination makes the capacitor insensitive to low impedance, which is one of the primary benefits of this particular product. Additionally, the aluminum-polymer construction of the capacitor guarantees a longer life than the traditional aluminum electrolytic capacitor. The internal construction of the 2.5SW470M2.9X7.3 consists of an anode foam, solid electrolyte and a cathode gel. This combination increases the capacitance value and the overall performance of the capacitor.
The application field of the 2.5SW470M2.9X7.3 aluminum-polymer capacitor includes DC-DC converters that operate at high voltage and current levels, meaning it can be used for tasks such as power smoothing, power factor adjustments and related applications. Additionally, its wide range of inductance and capacitance makes it suitable for pulse operation circuits, such as timer-regulated signal generators, and for energy storage devices, such as energy buffers and fly-back overvoltage protectors. Furthermore, it can also be used in high-frequency circuits, as the oscillating nature of the signal requires very huge reactance which can be obtained by the capacitor through its low Equivalent Series Resistance (ESR).
The working principle behind the 2.5SW470M2.9X7.3 aluminum-polymer capacitor is the same as the conventional aluminum electrolytic capacitor. The terminals of the capacitor are connected to the power supply, with one terminal being positive, and the other negative. This provides an electric field within the active region. The energy stored in the capacitor increases with the application of voltage, as the electric field generated in the active region results in the formation of ions between the anodic side and the cathodic side of the capacitor. The ions form a bridge that extends across the active region and provides a path to the movement of current. This results in the buildup of electrical energy, while at the same time providing a cycle of charge and discharge. The capacitance value of the 2.5SW470M2.9X7.3 depends on the Surface Area and the thickness of the electrodes, as well as the internal resistance of the capacitor.
