Aluminum Electrolytic Capacitors Overview

Aluminum electrolytic capacitors, commonly known as “electrolytic caps,” incorporate a thin layer of aluminum oxide on the surface of an aluminum foil to create a dielectric layer that separates a thin anode foil from the cathode. Applying a voltage to the terminals of the electrolytic capacitor causes positive charges to accumulate on the anode while negative charges accumulate on the cathode. The capacitor behaves like a battery, storing energy for a short amount of time and discharging when the voltage is removed. These capacitors are commonly used in power supplies, oscillators, radio frequency circuits, load-sensing and voltage-sensing circuits, and both AC and DC circuits. The aluminum electrolytic capacitors offer high charge and discharge rates, improved high temperature characteristics, and very long shelf life. They are also relatively inexpensive.

B41821A7108M000 Capacitor Overview

The B41821A7108M000 aluminum electrolytic capacitor is a radial leaded type with an axial body length of 28mm and a maximum diameter of 12.5mm. It has 10μF of capacitance and a rated voltage of 450VDC. It is part of the B41821 Series of EPCOS capacitors, which offers reliability in conditions that escape other aluminum electrolytic capacitors. It has a low tolerance value with a capacitance deviation of 6%, an operating temperature between -40 and +85°C, and a rated voltage of 450VDC. This professional grade aluminum electrolytic capacitor offers enhanced life and robustness in higher temperature and ripple current environments, as well as a longer operating life because of its inherent humidity protection. The B41821A7108M000 also offers low resistant behavior in applications with high ambient temperatures and an extended operating life in high humidity environments. The B41821A7108M000 is typically used in the input and output circuits of AC power supplies, as well as voltage-sensing circuits in TVs and servo systems. It is also used in guitar amps where it helps reduce noise or hum. The EPCOS capacitor is also commonly employed in audio-frequency circuits for rear view mirrors, CD players, and car radios.

B41821A7108M000 Application Fields and Working Principle

As an aluminum electrolytic capacitor, the EPCOS B41821A7108M000 is primarily used in applications such as power supplies, oscillators, radio frequency circuits, load-sensing and voltage-sensing circuits, and both AC and DC circuits. This capacitor is known for its efficient performance in filtering or smoothing pulsating currents, for energy storage, frequency control, noise reduction, or surge protection.The working principle of an aluminum electrolytic capacitor is based on the fact that it consists of an anode foil that is separated from the cathode by a thin dielectric layer made of aluminum oxide. When a voltage is applied to the terminals of the capacitor, positive charges accumulate on the anode while negative charges accumulate on the cathode. This charge separation creates an energy storage capacity that is known as capacitance. When the voltage is removed, the charges slowly discharge, releasing the stored energy.The unique design elements of the B41821A7108M000 capacitor provide a reliable and efficient performance in noisy or high temperature conditions. It offers improved life and robustness in high temperature and ripple current environments. The enhanced characteristics make it ideal for use in high-power applications, such as power supplies and voltage-sensing circuits. The low temperature coefficient of capacitance also ensures a higher operating life in high humidity environments. The B41821A7108M000 is a highly reliable aluminum electrolytic capacitor that is suitable for use in a wide range of systems. Its long lifetime and efficient performance make it an ideal choice for applications that require reliable energy storage and high performance.
