Aluminum electrolytic capacitors are widely used in many electronic components and are important components in AC / DC power circuits. The LQR2W681MSEC is an aluminum electrolytic capacitor which is specifically designed for surface mount applications. It has a high capacitance, long working life, excellent high temperature characteristics, and high ripple current.

The main application field of the LQR2W681MSEC is power supply circuits and low frequency circuits. High precision applications will benefit from its low impedance, small size, and low DC bias characteristics. In low frequency circuits, the capacitor can provide good SNR performance and high pass filtering. Additionally, it can also be used in high frequency filtering applications such as in TV sets and DVD players.

The LQR2W681MSEC aluminum electrolytic capacitor is based on a tantalum anode electrolyte and cathode with a single layer of aluminum foil. It can be operated between temperatures of -40 to +105°C, which makes it ideal for use in harsh environments. It features a rated life of 1,000 hours at +105°C and excellent ripple absorption performance.

The working principle of an aluminum electrolytic capacitor is based on a double layer of tantalum and aluminum foils separated by an electrolyte. When a voltage is applied across the device, the aluminum foil acts as a positive electrode and attracts the positive ions in the electrolyte. The negative ions flow to the tantalum foil, forming an electric double layer. This double layer is then charged and acts as an electric field between the two foils, storing energy.

The LQR2W681MSEC aluminum electrolytic capacitor also features a self-healing mechanism which helps to prevent the capacitor from further damage in case of an overvoltage or overcurrent. This feature helps to improve the reliability of the device and increase its service life. The self-healing mechanism works by creating an electric field to prevent the formation of a short circuit. Over time, the device is able to recover from any such damage.

The LQR2W681MSEC aluminum electrolytic capacitor is an excellent choice for a variety of applications. With its high capacitance, long working life, excellent high temperature characteristics, and high ripple current, it is ideal for use in power supply circuits and low frequency applications.
