Aluminum Electrolytic Capacitors and B41252A3159M Application Field and Working Principle

Aluminum electrolytic capacitors are characterized by their large capacitance in comparison to its volume. This type of capacitor utilizes an oxide film to form a dielectric which can hold a large amount of charge on both electrodes, allowing for a better relationship between their physical size and capacitance. Since aluminum electrolytic capacitors employ a liquid electrolyte, they’re not recommended for high temperature or vibration service applications.

The B41252A3159M is a traditional series of radial leaded aluminum electrolytic capacitors developed by TDK Corporation. This series has a voltage range of 6.3Vdc to 50Vdc and a capacitance range of 470μF to 8200μF, making it suitable for various circuit designs in the consumer, industrial, automotive, and medical industries. The temperature range of -40°C to +125°C and long-life qualities make them an excellent choice for connection in circuits.

Working Principle

Aluminum electrolytic capacitors are classifed as non-polarized capacitors, meaning their capacitor is connected to two electrodes and currents can flow in either direction. The anode of an aluminum electrolytic capacitor is composed of an aluminum foil electrode that is anodized, with the oxide layer serving as the dielectric for the device. The cathode of the capacitor is typically Niobium or Tantalum, with a electrolyte gel or ionic solid for its dielectric. Surrounding the anode and cathode layers is an outer covering that prevents electrical discharge from occurring between the two electrodes.

The B41252A3159M has a long life rating of 2000 or more hours with a temperature range of -40°C to +125°C, making it both versatile and reliable in its applications. With a maximum allowable rated ripple current of 6.78A at 85°C and a maximum 25V of rated permissible dissipation factor of 0.2% at 20°C, this type of aluminum electrolytic capacitor performs well in both low and high power applications.

Applications

B41252A3159M aluminum electrolytic capacitors are used in various applications, including power supplies, switching and resonant circuits, communication equipment and other electronic products. due to its long-life operations and its wide voltage ratings, they have become a popular choice for many electronic applications.
