Aluminum Electrolytic Capacitors are electrical components with unique properties, making them useful for many applications. The MAL213215472E3 is a specific type of capacitor and this article will discuss its application field and working principle.

The MAL213215472E3 is a type of polarised, non-solid aluminium electrolytic capacitor. It has a standard Tolerance of ±20%, an Operating Temperature of -55°C – +105°C and includes a silicone coating for added protection.

Given its specifications, the MAL213215472E3 is suitable for a wide range of applications. It is widely used in circuits and equipment requiring higher than average capacitance values, including timers, power supplies and amplifiers.

Capacitors such as the MAL213215472E3 operate on the principle of electrostatics. They consist of two metal plates separated by a dielectric material, which is a substance that does not allow any electric current to flow through it. A voltage applied to the plates create an electric field that causes an attraction or repulsion between the two plates, depending on the polarity. This creates an electrical charge that is used to store energy.

The MAL213215472E3 differs from other types of electrolytic capacitor in that it is of a radial design, meaning that it has the two plates arranged on either side of a central core. This radial design increases the surface area of the plates and increases the capacitance of the device. This makes the MAL213215472E3 suitable for higher capacitance values than other designs.

Another advantage of the radial design of the MAL213215472E3 is that it is self-healing. If the dielectric is compromised – for example, due to an excess of voltage – the aluminium plates will reform naturally and restore the initial capacitance levels.

The MAL213215472E3 is also highly reliable, thanks to its silicone coating and its low ESR values (Equivalent Series Resistance). The coating prevents corrosion to the plates over time and the low ESR values reduce the internal impedance of the device, preventing it from becoming inefficient over time.

In conclusion, the MAL213215472E3 is a highly versatile and reliable aluminium electrolytic capacitor. Its radial design gives it the ability to provide high capacitance values with low equivalent series resistance, while its silicone coating ensures that it remains reliable even in harsh environments.
