Aluminum Electrolytic Capacitors
Aluminum electrolytic capacitors can be identified with their unique model numbers. The model number 400QXW150MEFC18X31.5 is an aluminum electrolytic capacitor designed for motor driving applications. While each component of the model number may appear confusing on its own, the entire model number reveals important information about the specific capacitor. Understanding the components of the model number exhibits how the capacitor should be used.
Applications
Aluminum electrolytic capacitors are engineered to assist applications that require stronger currents than other types of capacitors. Additionally, their cost-effective design makes them desirable for many motor driving applications. The model number 400QXW150MEFC18X31.5 denotes a capacitor designed for use in driving large electric motors. This particular capacitor is designed to offer superior current control efficiency and provides better heat tolerance under higher currents.
Components of the Model Number
The model number identifies an Aluminum Electrolytic Capacitor due to its unique prefix and set of numbers that follow. The “400QXW150MEFC18X31.5” model number offers the following breakdown about the capacitor:
- 400V – Rated voltage of the capacitor.
- QXW – Classification code; indicates size, series and environmental-protection level.
- 150 – Designates capacitance in μF.
- MEFC18 – Indicates size and terminal shape of the capacitor.
- X31.5 – Temperature range this capacitor is designed for.
Working Principle of an Aluminum Electrolytic Capacitor
An aluminum electrolytic capacitor is a polarized capacitor that consists of two metal plates that are separated by a liquid electrolyte. The “positive” terminal is connected to the porous oxide-coated aluminum foil, while the other plate is connected to the electrolyte. The electrolyte also acts as the dielectric medium for the capacitor. When the capacitor is placed in a circuit and voltage is applied, the aluminum oxide acts as a dielectric, and an electric field builds.
The electric field stores the energy, which then provides the electrical insulation between the two terminals. The field allows positive charges to accumulate and be stored at the aluminum foil terminal. The other electrolytic plate will be charged with the opposite polarity. Since the electrolyte isn’t tightly bound by the oxide layer, and since some molecules can pass through, these molecules will drag the charged particles across the dielectric material, allowing the capacitor to stay charged.
Advantages of Using Aluminum Electrolytic Capacitors
Aluminum electrolytic capacitors offer several advantages that make them a popular choice for motor driving applications. Their design enables them to store more energy in a specific size compared to other types of capacitors. This makes them a good option for designing high-current power sources that require a smaller size. Additionally, aluminum electrolytic capacitors are resistant to heat and are able to dissipate more heat from their surface. This makes them useful in applications that involve temperature fluctuations.
Conclusion
Aluminum electrolytic capacitors are essential components used in motor driving applications, as they offer superior current control and heat dissipation capabilities. These capacitors can be identified by their model numbers, which provide information about the voltage, capacitance, temperature range, and size of the capacitor. Understanding the model number enables users to select the correct capacitor for their needs. Aluminum electrolytic capacitors work by accumulating a positive charge at one plate and a negative charge at the other plate, which separated by a dielectric medium.
