Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are one of the most common type of capacitors and are often referred to as “The Swiss Army Knife” of capacitors. This is because they are widely-used in a variety of applications and are available in an extremely wide range of sizes. Aluminum electrolytic capacitors can be broadly divided into two main types: polarized and non-polarized.

LKX2D821MESA45 Application Field and Working Principle

The LKX2D821MESA45 is a type of polarized aluminum electrolytic capacitor, commonly used in AC power supply circuits. The working principle behind these capacitors is based on the physical process of electrolysis. In electrolysis, an electrical potential is applied to an electrolyte solution, which ionizes the electrolyte solution and causes a charge to be stored on the electrodes of the capacitor. This stored charge is what provides the capacitance to the capacitor.

The LKX2D821MESA45 capacitors are typically used in AC power supply circuits, specifically in circuits that require heavy filtering of AC line voltages and currents. The device is optimized for applications that require a high frequency response, in the range of 100kHz to 3MHz. These devices are ideal for filtering AC line voltages as they are able to rapidly charge and discharge, enabling the capacitor to react quickly to changes in the input voltage. The LKX2D821MESA45 is a robust device that can handle temperatures ranging from -55°C to +105°C.

The LKX2D821MESA45 has a rated voltage of 25 VDC with a maximum operating voltage of 50 VDC. It is also rated for 85°C operation and has a maximum internal pressure of 2.76 x 10^-4 atm.

The polarized aluminum electrolytic capacitors like the LKX2D821MESA45 are widely used in AC line filtering power supplies due to their ability to rapidly charge and discharge which allows them to react quickly to changes in voltage. In these applications, the capacitors provide a low impedance path for AC signals while reducing interference and noise.

These capacitors are also used in the audio industry for amps and speaker crossover networks. Here, these capacitors help to reduce crossover distortion and minimize the frequency response deficits created by active devices in the circuit. They also help reduce interference from external noise sources in the environment.

In addition, the LKX2D821MESA45 capacitors can also be used in motor control applications, as these capacitors can provide a stable voltage supply for components in the circuit such as an LED display. They can also reduce the noise generated during motor start up and improve motor efficiency.

In conclusion, the LKX2D821MESA45 are high-performance polarized aluminum electrolytic capacitors optimized for 400kHz - 3MHz AC line filtering applications. These capacitors are ideal for reducing noise, interference, and crossover distortion in audio, motor control, and power supply applications. The device can handle ambient temperatures ranging from -55°C to +105°C and is rated for a maximum operating voltage of 50 VDC.
