Aluminum Electrolytic Capacitors

Capacitors are electrical components used to store energy and provide surge capacity for systems that require higher power briefly. Electrolytic capacitors use an electrolyte, typically made of aluminum, to store their charge and range from a few microfarads to thousands of microfarads of total capacitance. The 100ZLH220MEFCG412.5X25 is an electrolytic capacitor employing an aluminum electrolyte and is used in a wide variety of applications and equipment to store and manage an electrical charge.

Application Field

The 100ZLH220MEFCG412.5X25 electrolytic capacitor is a high-temperature electrolytic capacitor designed for use in the industrial applications. It has a capacitance of 220μF and an operating temperature up to 125°C. The capacitor is RoHS compliant, making it suitable for use in the current trend of green electronics. It is most commonly used in power supplies, automotive and renewable energy applications, as well as many other industrial applications where its high surge current capability and long-term reliability are advantageous.

Working Principle

The internal workings of an electrolytic capacitor are based on Faraday’s law of capacitance, with a thin layer of oxide forming the dielectric layer between the anode and cathode. It is this dielectric that separates the anode and cathode apart, allowing the capacitor to store charge and manage current. The 100ZLH220MEFCG412.5X25 capacitor uses an anodic layer of aluminum as the anode material and is thus referred to as an ‘aluminum electrolytic capacitor’. The construction and materials of an electrolytic capacitor make it an ideal choice for storing electrical charge and providing surge current to systems requiring higher levels of current than normal.

In order to ensure an even distribution of electrical current, the 100ZLH220MEFCG412.5X25 capacitor is constructed using a design process known as ‘stacking’. This process involves stacking multiple layers of aluminum and foil together to form a solid structure, with the aluminum acts as the anode and the foil as the cathode. Stacking allows for the capacitor to have greater capacitance and provide improved surge current capabilities.

All electrolytic capacitors are polarised, meaning that they need to be properly orientated with respect to the positive and negative connections. Generally, electrolytic capacitors are marked with a longer positive lead, making it easy to identify which lead is which. This is critically important to ensure the correct connections, as reverse polarity may result in leakage and failure of the capacitor.

Overall, the 100ZLH220MEFCG412.5X25 Aluminum Electrolytic Capacitor is an essential component in many industrial applications, providing reliable performance and excellent surge current capabilities. With its long term reliability, rugged construction and versatile design, it is well positioned to meet the needs of many industries.
