Aluminum electrolytic capacitors (also known as electrolytic caps or e-caps) are polarized capacitors traditionally manufactured with aluminum oxide film as the dielectric. Such devices come in many sizes, shapes, and fom-factors, and they can be used in a plethora of applications. The capacitance value ranges of an aluminum electrolytic capacitor typically fall between 1μF and 2000μF and they typically can operate in temperatures up to 105°C. One such example of an aluminum electrolytic capacitor is the EKZN350ELL181MHB5D.

The EKZN350ELL181MHB5D is part of the EKZN seriese of aluminum solid electrode electrolytic capacitors developed by Nichicon, a Japanese electronics manufacturer. This device features a combination of low ESR and low impedance characteristics for improved performance and stability. This capacitor supports high ripple current and is also designed to ensure long life for a wide variety of applications. Its speciality is that it has an extended operating temperature range, from -55°C to 105°C with an ultra-low impedance of 1.8Ω at 120Hz.

The aluminum electrolytic capacitor EKZN350ELL181MHB5D is suitable for use in multiple points, such as inverter, servo motor, and VFD. It serves in high voltage switching power applications, power transmission and distribution systems, light dimmer circuits, and power circuits. It is also suitable for automotive, aerospace, medical, and military applications, as these types of applications require extreme performance and reliability. The device supports up to 280V voltage and has a low ESR value of 0.41Ω.

The EKZN350ELL181MHB5D also has a wide range of typical working applications, such as in motor drive systems as well as in AC/DC switching power supplies, alternative energy applications, medical equipment, and inverter. This device is often preferred in motor drive systems as it provides greater exposure to shock, vibration, and other environmental effects. In addition, it is preferred for its great temperature stability, a very important factor when considering the maximum permitted ambient temperature.

The basic working principle of aluminum electrolytic capacitors is quite straightforward. Two metal plates are separated by a thin sheet of aluminum oxide, an electrolytic dielectric material. When an external electric field is applied to the capacitor, the positive ions in the electrolyte are attracted to the negative plate and the negative ions in the electrolyte are attracted to the positive plate, creating two opposite positive/negative electric fields that overlap and polarize the oxide film. This creating a capacitance that can store a limited amount of electrical charge. The capacitance of the capacitor is then determined by the geometry of the plates, the distance between them, and the relative permittivity of the oxide film.

In short, the EKZN350ELL181MHB5D is a highly reliable aluminum electrolytic capacitor that can be used in a wide range of applications, from industrial machines and automotive applications, to power supplies, motors, and many more. Its extended temperature range and low ESR make it an attractive option for applications that require long lifespans and extreme environmental conditions.
