Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor is an electrolytic capacitor that provides high capacitance value per unit volume which is used in power electronics and electrical systems for applications such as energy storage, filtering, timing, motor starting, and noise reduction. It consists of two aluminum foils, each rolled with a thin oxide film inside it, separated by a thin layer of dielectric material like paper or a polymer film. The distance between the two aluminum foils determines the capacitance value of the capacitor. The positive aluminum foil is then connected to the positive terminal of the capacitor, while the negative terminal is connected to the other aluminum foil.

HVMLS221M250EK1D application field and working principle

The HVMLS221M250EK1D is an aluminum electrolytic capacitor specifically designed for applications requiring high capacitance values with a wide operating temperature range. The capacitor is used in automotive electronics, solar grid inverters, power supplies, and consumer electronics. The capacitor can store energy, filter signals, reduce power losses, and reduce noise in the power delivery system. The working principle of the HVMLS221M250EK1D aluminum electrolytic capacitor involves two thin foil plates of aluminum, each rolled with a thin oxide layer, separated by a dielectric material. When a voltage is applied to the capacitor, a strong current is generated which forms an electric field between the two aluminum foil plates. The electric field generates a charge that accumulates on the inner surfaces of the oxide layers. This charge creates an electric field that is opposite of the applied voltage, resulting in a capacitance effect. This capacitance effect is used to store energy, to filter signals, or to reduce power losses and noise in the system.

The first key feature of the HVMLS221M250EK1D aluminum electrolytic capacitor is its large capacitance value per unit volume. It can provide up to 221 microfarads of capacitance in a volume of 0.2 milliliters. This means that the capacitor can store energy much more efficiently and compactly than other types of capacitors. The second key feature is its wide operating temperature range. The capacitor can be used in conditions between -40°C and +125°C, making it suitable for use in difficult environmental conditions. The third key feature is its low equivalent series resistance (ESR). This allows for higher power efficiency and reduced power losses during operation. It also features improved ripple current handling, making it suitable for use in power delivery systems that require high levels of current.

The HVMLS221M250EK1D aluminum electrolytic capacitor is a reliable and durable high-performance component that can provide a variety of benefits to power electronics and electrical systems. It can store energy more efficiently, filter signals, reduce power losses and noise, and handle higher currents. This makes it suitable for a wide range of applications, including automotive electronics, solar grid inverters, power supplies, and consumer electronics.
