Aluminum Electrolytic Capacitors: SLP181M350C3P3 application field and working principle

Aluminum electrolytic capacitors, also called tantalum electrolytic capacitors, are capacitors which use an electrolyte (usually an organic solvent) as the dielectric medium. They are the capacitors that are most commonly used in applications for general electronic purpose.

Application field for SLP181M350C3P3 Aluminum Electrolytic Capacitors

The SLP181M350C3P3 aluminum electrolytic capacitor is used in a variety of electronic applications such as power supplies, audio, as well as in industrial and automotive applications. It is a surface-mount type capacitor suitable for both low-temperature operation (down to -55°C) and high-temperature operation (up to 125°C). It is available in various capacitance values ranging from 0.1 to 2.2µF. It claims to provide excellent long-term stability and high reliability. Being a non-polarized type, it can be used in applications that require positive and negative power supplies without any time-poling. It is a popular choice for applications requiring high pulsed current ripple capability.

Working Principle of SLP181M350C3P3 Aluminum Electrolytic Capacitors

The SLP181M350C3P3 aluminum electrolytic capacitor features special aluminum electrolytic in which electrically conducting anode foil, electrolyte and separator are laminated and rolled up. It is then placed in a can-shaped case and sealed. A pressure relief valve is fitted for higher capacitance values.

The working principle of such capacitors is simple. When a voltage is applied, positive charges are stored in the anode, while negative charges stored in a dielectric layer. These, in turn, are kept at a distance from each other by an insulating layer embedded in between the anode and the dielectric layer. This result in an electric field between the two layers. The electric field helps in storing energy and thus allowing the capacitor to act as a filter for current.

SLP181M350C3P3 aluminum electrolytic capacitor has high volumetric efficiency, which helps to reduce physical size and cost, while still offering capabilities for excellent performances. With its close capacitance tolerance, low ESR, excellent long term stability and corona-resistant properties, this capacitor is an ideal choice for high power and temperature control applications.
