It has a maximum capacitance of 8.2uF, an operating temperature range of −40°C to 105°C, and a maximum ESR rating of 19 Ω.

Aluminum electrolytic capacitors have many different types. The 672D826H050DM5D is a type of miniature aluminum electrolytic capacitor and the outer size is 6.3mm×7.7mm. This type of capacitor has several advantages for use in small electronics circuits, including low resistance, high capacitance, low ESR, excellent temperature characteristics, and excellent ripple-current capability. It is suitable for use with compact and high-density electronic devices.

The working principle of an aluminum electrolytic capacitor is based on the capacitance effect in a formed electrolyte layer. The aluminum electrolytic capacitor has two plates: an anode plate and a cathode plate. The anode plate is made of aluminum foil with a thin oxide layer to form the capacitor’s dielectric layer, while the cathode plate is formed from a ribbon of aluminum, which is then wound onto a metal core. The two plates are separated by an electrolyte, usually a solution of boric acid and borates.

The oxide layer of the anode serves to increase the surface area of the anode; when a voltage is applied across the two plates, an electric current is drawn from the anode and passed through the electrolyte and into the cathode. This current causes dissociation of electrolyte molecules, forming positively charged ions that attach to the oxide layer and negatively charged ions that are attracted to the cathode plate. When the electric field between the two plates reaches a certain intensity, a charge separation occurs, thus forming the capacitance and acting as a barrier to current flow.

The 672D826H050DM5D aluminum electrolytic capacitor is used to couple an input and output and suppress interference signals. It can also be used to smooth the voltage attainable from a power supply, and reduce the impact of a sudden voltage change.
