Aluminum electrolytic capacitors are widely used as short-time energy storage devices in power supply and signal processing circuits due to their simplicity, cost effectiveness and good performance. The EKZH160ELL182MJ25S belongs to this device category and is a radial-type aluminum electrolytic capacitor, characterized by high reliability and long service life. The application and working principle of this capacitor will be discussed in this article.

Application of EKZH160ELL182MJ25S:

The EKZH160ELL182MJ25S is a high voltage (160V DC) axial-type aluminum electrolytic capacitor and has long been used for capacitive-equalization applications and as a coupling device in high-voltage circuits. Under normal operating conditions, the EKZH160ELL182MJ25S is able to store electrical charge up to a peak voltage of 500V, thus being ideally suitable for applications such as motor starters, AC-adjustable speed drives, and high voltage control systems. In addition, these capacitors have also been employed extensively in automatic voltage regulators, voltage detection and control systems, as well as other signal and power processing circuits. In all of the above mentioned applications and more, the EKZH160ELL182MJ25S provides outstanding performance and long life due to its low Equivalent Series Resistance (ESR) and low leakage current.

Working Principle of EKZH160ELL182MJ25S:

The EKZH160ELL182MJ25S is an aluminum electrolytic capacitor that relies on an electrolytic liquid (for example: ethylene glycol or EDTA) within its cylindrical aluminum case to provide the capacitance. This liquid has the unique property of ionizing when an electrical field is applied. As electrical current flows into the capacitor from one terminal, it produces an electrical field that causes the liquid’s molecules to polarize. This creates an electrostatic field between the anode and cathode plates, which allows capacitive coupling and thus stores electrical charge. When the current is removed, the opposite polarity field is produced and the capacitor discharges.

The EKZH160ELL182MJ25S has a high temperature operating range of -40 to +125 degrees Celsius and can be used over a wide temperature range without compromising its performance. Aside from that, it also comes with a electrolytic liquid venting feature that allows the capacitor to slowly release excess pressure without damage caused by mechanical failures.

In conclusion, the EKZH160ELL182MJ25S is an ideal choice for capacitive-equalization and coupling applications in DC power/signal processing circuits. With its long life and wide operating temperature range, it has been used extensively in a wide range of applications, from AC adjustable speed drives, voltage regulation systems, and motor starters, to voltage detection and control systems.
