Aluminum Electrolytic Capacitors are an important component in many electronic circuits and devices. They’re widely used because of their low cost, good electrical properties, high capacitance, and long life. The LQR2G681MSECBN is an Aluminum-Electrolytic Capacitor and its application field and working principle will be discussed in this article.The LQR2G681MSECBN is a surface mount electrolytic capacitor, specifically designed for high-frequency applications in automobiles and consumer electronics. It offers superior performance and excellent reliability in harsh environments. As a result, the LQR2G681MSECBN is widely used in applications such as motherboard bypass capacitors, LED backlighting, automotive and truck audio systems, and a variety of audio and video equipment that has digital or analog processing stages.The LQR2G681MSECBN is defined by a number of performance metrics, which include capacitance, maximum operating temperature, rated voltage, and equivalent series resistance (ESR). The capacitance range of the LQR2G681MSECBN is 47uF to 220uF, and the maximum operating temperature is 105°C. Its rated voltage is 2.5V and its ESR is typically between 0.11 and 0.86 ohms.The working principle of Electrolytic Capacitors, such as the LQR2G681MSECBN, is based on the electrical double layer that forms at the surface of the anode of the capacitor. The double layer is formed by the combination of a thin layer of negatively charged ions adhered to the anode surface, and a thinner layer of positively charged ions deposited on top of the negatively charged ions. The double layer creates an electrically non-conductive barrier that can store electric charge.To use the LQR2G681MSECBN in the application, it must first be placed on a printed circuit board (PCB). Avoid handling the capacitor directly, as oil and dirt on the fingertips can damage the capacitor and render it useless. Once the capacitor is in place, two signal pins must be soldered to each of the two capacitor terminals on the PCB. This will allow the capacitor to form the electrical connection required to power the circuit.Finally, the two circuit pins and capacitor terminals must be connected to the two signal pins. Typically, the two signal pins must be connected to a voltage source, such as a battery, power supply, or other power supply component. This allows the capacitor to store the electrical charge and supply the necessary voltage to power the circuit.In conclusion, the LQR2G681MSECBN is an Aluminum Electrolytic Capacitor and is typically used in high-frequency applications, such as motherboard bypass capacitors and automotive audio systems. Its design parameters include a capacitance range of 47uF to 220uF, a maximum operating temperature of 105°C, a rated voltage of 2.5V, and an ESR typically between 0.11 and 0.86 ohms. Its working principle is based on the electrical double layer that forms at the surface of the anode of the capacitor, which creates an electrically non-conductive barrier capable of storing electric charge. With these factors in mind, the LQR2G681MSECBN can be used in a variety of applications to provide reliable and efficient electrical power.
