The electrolyte is an essential component of an electrolytic capacitor and provides the conductive medium through which the capacitor’s electrical charge is stored and released. It is typically a liquid, paste, or gel that is placed between the two electrodes of a capacitor. A capacitor’s electrolyte can be any material that allows for an electric current to flow through it.
The most common types of electrolytes used in these capacitors are electrolytic solutions containing dissolved salts of metals. The electrolytes used in electrolytic capacitors allow for the capacitor to have a certain voltage rating. When a voltage is applied to the capacitor, it causes an electric field to spread through the electrolyte solution.
This electric field causes deposition of metal ions on the electrodes of the capacitor, forming an electrical double layer between them. This double layer increases the capacitance of the capacitor. When the electrolyte evaporates, the molecules of the volatile solvent become disconnected from the solid environment and partially escape in the form of gas.
This gas escapes from the capacitor, and has to be replaced if the capacitor is going to remain functional. As such, it is important to use a capacitor with an electrolyte that is both high in quality and suitable for the application.
The choice of electrolyte can affect the physical and electrical characteristics of the capacitor, such as capacitance, equivalent series resistance, leakage currents, and other factors that can influence performance.
The Global capacitor electrolyte market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
The UCK Series of Chip-Type Aluminum Electrolytic Capacitors with High Capacitance and Low Voltage is Introduced by NICHICON Corporation. These products are perfect for use in telecommunications and automotive equipment. Based on our accumulated technology is the UCK series. It uses an electrode foil with a high capacitance to achieve both miniaturization and high capacitance.
Thus, in comparison to the UCM series, the current chip-type product rated at 105°C, the UCK series achieves a maximum increase in capacitance. The series helps to create terminal and device designs that are smaller. Additionally, the UCK series is 30% shorter in height than the current UPW series of radial leaded capacitors with the same capacitance. This results in labor savings and a lower profile when surface mounting.
There is a growing need for chip-type aluminum electrolytic capacitors with equivalent capacitance to replace radial lead-type aluminum electrolytic capacitors due to the trend in many industries toward surface mounting of electronic components. Higher-capacitance aluminum electrolytic capacitors that are more compact are always in demand, as are high-capacitance capacitors for use in power backup and other applications. To address these market demands, they introduced the UCK line of chip-type aluminum electrolytic capacitors.
