Aluminum Electrolytic Capacitors

EKZM160ELL471MHB5D is an aluminum electrolytic capacitor from the EKZM series, manufactured by YAGEO. It has a maximum voltage of 160 VDC, a minimum of 10 VDC and a capacity of 470 μF. Its dimensions are 16 × 25 mm, and it has a ripple current of 5.6 Amp.

Application Field

Aluminum electrolytic capacitors are used to store and filter currents and voltages in power supplies. In addition, they can be used in signal circulation circuits and signal smoothing filters. They are mostly used in the fields of signal processing, power management and control, filtering of audio and video signals, communication equipment, inverters and TV sets.

The EKZM160ELL471MHB5D has a maximum temperature rise of 85°C (125°C at 85°C of ambient temperature) and an endurance of 1500 hours to 85°C, making it suitable for use in areas with high temperatures. Its miniature dimensions make it suitable for use in small spaces and make it popular in the audio and video industries.

Working Principle

An aluminum electrolytic capacitor is constructed with two aluminum plates spaced apart by an insulating material called an electrolyte. A weak oxide layer is formed on the aluminum plates when they are exposed to the electrolyte. This oxide layer forms the capacitor dielectric. The electrolyte acts as an ion bridge between the two plates, acting as an electrolytic conductor.

The two plates act as two oppositely charged plates, forming an electric field. The electric energy is stored and can be released when needed through the reduction of this electric field. This allows the capacitor to filter AC signals and filter noise while preventing DC voltage from flowing through.

While traditional capacitors are composed of one or two paper dielectrics, aluminum electrolytic capacitors are composed of an additional anode made from aluminum foil and tightly wound around a winding core. The capacitor\'s value, or tolerance, is determined by the number of turns, the insulation gap between the anode and the winding core, and the surface area of the anode. This type of capacitor has the advantage of being able to provide very large capacities compared to other types of capacitors.

The EKZM160ELL471MHB5D is an electrolytic capacitor that is popular in the audio and video industries due to its high temperature performance, miniaturized form factor, and high capacity. Its components and construction make it suitable for a wide range of applications in power and signal processing.
