Aluminum electrolytic capacitors are widely used in the field of electronics and are essential components of many types of electrical and electronic equipment. The B41821A3277M000 is an aluminum electrolytic capacitor that has been widely adopted for various applications.

Description

The B41821A3277M000 is an aluminum electrolytic capacitor featuring an operating temperature range of -40°C to +85°C and a rated voltage of 16V. It has an ESR of 0.028 ohm at 120Hz and a maximum ripple current of 47.2mA (at 85°C/120Hz). It is constructed from an anodic aluminum alloy case and two threaded terminals. It also features a plasticized polypropylene dielectric.

Application Fields

The B41821A3277M000 capacitor is well-suited for a variety of applications where stability, low ESR, and high ripple current are required. It is most often used in the power supplies of automotive electronics, consumer electronics, and medical devices. Additionally, it is used for switching power supplies, DC-DC, switching current, and lightning impulse.

Working Principle

Aluminum electrolytic capacitors are polar capacitors that use an anode, a cathode, and an electrolyte between them to store electrical charge. They work by using an electrolyte solution to bridge the gap between the two electrodes, which is then held in place by a dielectric layer between them. This dielectric layer can be plasticized polypropylene.

When current is first applied to the capacitor, the electrolyte is forced into the gap and reacts with the anode and cathode, forming an oxide film. This film forms a barrier that blocks current flow, thus allowing the capacitor to hold a charge. The oxide film also improves the capacitance of the device and helps reduce ESR and reduce ripple current.

When the capacitor is discharged, the oxide film breaks down and the electrolyte is expelled back into the electrolytic solution. This process is reversible, which allows the capacitor to be used repeatedly for applications such as energy storage and filtering.

The B41821A3277M000 capacitor is an excellent choice for a wide range of applications that require not only low ESR and ripple current but also reliable performance and stability over a range of temperatures. The durable construction and extended temperature range also make it well-suitable for automotive and medical applications.
