Aluminum-polymer capacitors are a type of horizontally polarized supercapacitor which includes a dielectric electrolyte and two aluminum electrodes. They offer high electrochemical stability and low resistance, leading to the high power density, low frequency noise rejection and very low leakage current they are known for. The PCJ0E821MCL6GS is one of many models of aluminum-polymer capacitors that can be found in the market. This article seeks to explain the applications, benefits and working principle of the PCJ0E821MCL6GS.

Applications of the PCJ0E821MCL6GS

The PCJ0E821MCL6GS aluminum-polymer capacitor is designed for a range of applications that require the storage and release of energy quickly and reliably. Such applications include power supplies, high-end audio equipment, and resistance welding machines. The capacitor’s high power density, low resistance, long life, small size and low cost per Joule of stored energy make it a viable candidate for a wide range of applications. Additionally, its high capacitance, high operating temperature range, and low equivalent series resistance (ESR) also mean it can handle high pulse and high ripple current, making it a suitable choice for applications such as electric vehicle traction converters and flywheels.

The PCJ0E821MCL6GS can also be used in LED lighting systems thanks to its low ESR, and fast charging and discharging performance. Its small size, long life and fast switch-on time mean it is suitable for applications such as dimming systems, LED drivers, and compact power conversion modules. It is also used in mobile phones and tablet computers because of its fast response time, low ESR and low leakage current.

Benefits of the PCJ0E821MCL6GS

The PCJ0E821MCL6GS offers several important benefits:

• High power density: The device boasts a high power density of 1.0 kW/dm3, making it is an ideal choice for applications that require a rapid, accurate release of stored energy.
• Low equivalent series resistance: Its ESR is 2 mOhms, meaning it can handle highripple and high pulse current with minimal resistance. Its low ESR also makes it suitable for LED lighting systems and mobile phones.
• Wide operating temperature range: The PCJ0E821MCL6GS can operate in temperatures between minus 40 Celsius and 105 Celsius.
• High capacitance: Its capacitance of 2.7V is sufficient for a range of applications, including power conversion modules and electric vehicle traction converters.
• Long life: The capacitor offers a shelf life of up to 10 years at a temperature of 20 Celsius.
• Low leakage current: Its leakage current is 1nA or less, meaning it can be safely used in mobile devices, such as mobile phones and tablets.

Working Principle of the PCJ0E821MCL6GS

The aluminum-polymer capacitor of the PCJ0E821MCL6GS consists of two aluminum-laminated electrodes, which are separated by a dielectric material containing a gel electrolyte. When a voltage is applied across the electrodes, a thin layer of current is formed(leakage current ), which is responsible for the capacitor’s low equivalent series resistance. The electricity stored in the capacitance is then released in the form of a current, as required by the application.

In summary, the PCJ0E821MCL6GS aluminum-polymer capacitor is a reliable, high-quality device that can store and release energy quickly and reliably. Its high power density, low ESR, wide operating temperature range, high capacitance and long life make it a suitable choice for applications such as LED lighting systems, electric vehicle traction converters and mobile phones.
