Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors (also known as Al Caps or electrolytic capacitors) are a type of capacitor with a very high electrical capacitance and are widely used when high capacitance values are required. The capacitance of an aluminum electrolytic capacitor is usually much larger than that of other types of capacitors, such as ceramic, tantalum or paper capacitors. Due to their large capacitance values, aluminum electrolytic capacitors are often used in applications where space is limited and component count needs to be minimized.

MLS401M150EK0C Application Field and Working Principle

The MLS401M150EK0C aluminum electrolytic capacitor is a high-voltage radial-type capacitor that is designed for applications that require high performance. The capacitor features an operational voltage rating of 150V DC, a capacitance range of 0.47-2.2uF, and a tolerance of ±20%. The capacitor is also suitable for use in high-temperature applications, with a temperature range of -40 to +125°C.

The working principle of the capacitor is based on the physical properties of aluminum and electrolytes. The capacitor uses a pair of aluminum foils, which are separated by paper and a thin oxide layer. The foils are then rolled and inserted into a container filled with an electrolyte, and sealed in place. An electrical voltage is then applied across the aluminum foils, and electrons flow from one foil to the other, forming a new oxide layer at the surface of the electrode. This oxide layer increases the capacitance of the device and forms an electrical barrier. The capacitance of the capacitor is affected by the type and thickness of the oxide layer, as well as its surface area.

The MLS401M150EK0C aluminum electrolytic capacitor is ideal for applications that require high voltage operation, such as motor drive and inverter circuits, power units and control circuits. The capacitor also offers higher temperature capabilities and is suitable for use in high-temperature applications. The capacitor is also suitable for use in automotive applications, providing reliable operation even in extreme environmental conditions.
