Aluminum Electrolytic Capacitors

Introduction

Aluminum electrolytic capacitors are commonly used components in electronic circuits and are typically used to store charge or filter signals in low frequency applications. They are electrolytic capacitors which contain an electrolytic material, like aluminum oxide, separating two metal plates. When a voltage is applied, an electric field is generated in the electrolyte which causes a redistribution of charges to build up electrostatic capacitance. Every aluminum electrolytic capacitor consists of an anode, cathode, dielectric layer, and electrolyte layer.

B41231B9278M000 application field and working principle

The B41231B9278M000 is an aluminum electrolytic capacitor manufactured by TDK. It is a non-polarized, snap-in type capacitor and is designed for medium- and high-frequency applications in audio, video, and power circuits. The capacitor has an operating temperature range of -40 °C to +105 °C and is rated for a capacitance value of 2.2µF, rated voltage of 50V, and a rated ripple current of 1.660 mA. It has a physical size of 18 mm in diameter and 28.4 mm in length and an insulation resistance of 500 mohms or higher.The B41231B9278M000 aluminum electrolytic capacitor is constructed with two metal plates that are separated with a dielectric material and submerged in an electrolyte. The metal plates are called the anode and the cathode, and when a voltage is applied across them, an electric field is formed in the middle. This creates an accumulation of charge on either side of the capacitor, which stores energy analogous to a battery. When the voltage applied to the capacitor changes, the electric field reorients itself to oppose that change, providing a buffer. This process of charging and discharging allows the capacitor to store and release energy on demand, enabling it to be used for filtering and other signal conditioning purposes.
