381LR681M200H452

Aluminum electrolytic capacitors are one of the most widely used capacitors in the electronics industry. The construction of aluminum electrolytic capacitors makes use of the principle that the dielectric (insulating) material between two conductors acts as a barrier to electric fields, allowing an electric charge to be stored safely. These types of capacitors are commonly referred to as "aluminum electrolytic capacitors" due to their unique design which uses an anodized or electrolytically deposited aluminum foil as the dielectric material. The model number 381LR681M200H452 is a non-polarized aluminum electrolytic capacitor. This specific model is used in applications such as AC/DC power supplies, inverters, and motor drives which require high electrical current and high capacitive energy storage. The working principle of these capacitors is based on the principle that when a voltage is applied across two conductive surfaces (the anode and the cathode), the electric field generated between them creates an increase in negative ions on the anode due to electrostatic attraction of the electrons. Conversely, a negative voltage on the anode causes the positive ions to move towards the cathode, resulting in a reduction of the negative electrical charge on the anode. This process continues in a cyclical fashion, resulting in a steady charge interface between the anode and the cathode.The 381LR681M200H452 aluminum electrolytic capacitor is typically formed from aluminum foil that has been anodized or electrolytically deposited. This provides a thin layer of insulation between the anode and the cathode, thereby increasing the capacitive energy storage of the capacitor. The anode and cathode layers are further separated by a thin film of electrolyte material, which facilitates charge transfer between the anode and the cathode when a voltage is applied.The 381LR681M200H452 aluminum electrolytic capacitor is a high temperature type, meaning that it is designed for use in applications that require higher operating temperatures. These capacitors are typically rated for use in temperatures up to 180°C. This makes it an ideal choice for applications such as motor drives and power supplies, which operate at higher temperatures, and require high levels of energy storage. The 381LR681M200H452 aluminum electrolytic capacitor is also designed for high ripple current capability. Ripple currents are changes in electrical current that occur in alternating current circuits, and they can cause damage to the capacitor if they are not properly accounted for. This model is designed to withstand up to 100mA of ripple current, which is sufficient for most applications.In conclusion, the 381LR681M200H452 is a high temperature, high ripple current, non-polarized aluminum electrolytic capacitor. It is commonly used in applications such as AC/DC power supplies, inverters, and motor drives, where high electrical current and capacitive energy storage is required. This model makes use of an anodized or electrolytically deposited aluminum foil as the dielectric material, and it is rated for operation in temperatures up to 180°C. The thin film of electrolyte material that separates the anodes and the cathodes further enhances the capacitive energy storage of the capacitor, and it is designed to withstand up to 100mA of ripple current.
