Aluminum - Polymer CapacitorsAluminum - Polymer capacitors (also known as Al-poly capacitors) are now being increasingly used in applications due to their small size, low impedance, and excellent high temperature stability. These capacitors are becoming increasingly important in both military and civilian applications.Aluminum- poly capacitors are constructed using two main materials, an aluminum foil and a polyethylene polymer film. The aluminum foil acts as the conductive electrode while the polyethylene polymer film acts as the dielectric. When a potential is applied to these electrodes, the polyethylene polymer film develops a built-in electric field which stores energy. The amount of energy stored depends on the thickness of the polyethylene polymer film and the area of the electrodes.The 337UVR2R5MEW aluminum-polymer capacitor from TDK is a surface-mount device that offers very low losses and a broad range of capacitance values up to 5μF at 25V. This capacitor is ideal for use in industrial and consumer electronics, due to its low impedance and resistance to vibration and shock. The capacitance of the 337UVR2R5MEW is determined by the area of the conducting electrodes, the thickness and permittivity of the polymeric film, and the distance and angle between them. The capacitor also has an 85℃ temperature rating, making it suitable for a wide range of temperature-sensitive applications.The 337UVR2R5MEW aluminum-polymer capacitor has wide application fields. It can be used to filter out noise in signal lines, power lines and circuits, store energy and act as energy dampeners. Some of the other applications of the 337UVR2R5MEW aluminum-polymer capacitor include power supply protection, over-voltage and over-current protection, electrical noise suppression, decoupling, signal line protection, and power supply filtering.The working principle of the 337UVR2R5MEW aluminum-polymer capacitor is fairly straightforward. When a voltage is applied to the capacitor, the electrical charges build up between the two conducting electrodes. This creates an internal electric field which can store energy. The capacitance of the 337UVR2R5MEW, determined by the area of the electrodes, thickness/permittivity of the polymer film and distance/angle between them, dictates the amount of energy that can be stored. The capacitor can then be discharged when needed, providing a current to the circuit.In conclusion, the 337UVR2R5MEW aluminum-polymer capacitor is an ideal choice for a wide range of applications due to its low losses and high temperature stability. It is a durable, reliable capacitor with a wide range of applications including noise suppression, decoupling, power supply protection, and signal line protection. The 337UVR2R5MEW also offers a wide range of capacitance values, enabling it to be used in a variety of different applications.
