Aluminum Electrolytic Capacitors are distinguished by the dielectric, which consists of an aluminum oxide covered with an anodic coating on the surface of an aluminum foil. These capacitors are particularly suited for high-frequency filtering, energy storage, bypass applications, and polarized timing circuits. The AVES474M50B12T-F, in particular, is a high-quality electrolytic capacitor that fits in a radial leaded case. It offers long life, low equivalent series resistance, and good characteristics.

The AVES474M50B12T-F has a rated capacitance range from 47µF to 470µF and a rated voltage range from 4V to 50V. It is enclosed in a radial-leaded aluminum housing and has a maximum temperature range of 105°C. The AVES474M50B12T-F uses M-type electrolyte, with a capacitance tolerance of ±20%. With this capacitor, surge voltages may reach up to 315V.

The AVES474M50B12T-F application fields are numerous, although it is mainly used as bypass, blocking, coupling, or summing capacitors in filter and timing circuits. Additionally, decoupling capacitors, energy storage for circuits, and snubbering capacitors are other primary capabilities of the AVES474M50B12T-F. The capacitor features high frequency characteristics. In addition, it offers increased life cycle expectancy and has excellent overall performance even at elevated temperatures.

Aluminum Electrolytic Capacitors feature a two-terminal construction and use an insoluble electrolyte between the positive and negative plates of the capacitor. The AVES474M50B12T-F extends the voltage value of the capacitor with an applied voltage to the negative pole. Thus, its working principle is mainly based on the electrical Field Polarization in the dielectric. More precisely, the polarizing voltage acts over the aluminum oxide. It resurges the negative polarizations, also called “Fringing Field”.

When the capacitance depends on this type of resurging, it implies that the static capacitance it can withstand is higher than when the residual across currents are present. That is what makes Aluminum Electrolytic Capacitors so different from any other capacitance type, particularly the AVES474M50B12T-F. This also explains why this type of capacitors withstands higher currents and voltages without leakage.

Additionally, a key peculiarity of the AVES474M50B12T-F is its self-healing characteristic. The self-healing permeability is provided by the diffusion of holes in the dielectric, which implies that when any short-circuit event takes place, its overload condition dissipates via evaporation of the electrolytic.

The AVES474M50B12T-F is further distinguished as being a low-loss capacitor with a low equivalent series resistance. It ensures the capacitor has low power-loss in AC circuits and a lowered heat generation.

In conclusion, the AVES474M50B12T-F is an efficient electric polarized capacitor. It features a high capacitance range and robust performance. Thanks to the self-healing characteristic and the extended voltage range with low equivalent series resistance, this aluminum electrolytic capacitor has many applications, such as blocking, bypass, snubbering, or coupling capacitors. Besides, its low-loss characteristic makes it suitable for high-frequency filtering.
