Aluminum - Polymer Capacitors: RR70G122MDN1PH Application Field and Working Principle

Aluminum-polymer capacitors have made huge strides in recent years to become a more popular choice among professional and personal electronic users. An aluminum-polymer capacitor, also commonly known as an aluminum-polymer electrolytic capacitor, is an incredibly efficient energy storage device that allows for high-density designs, saving valuable real estate in modern electronics. The RR70G122MDN1PH is a highly efficient aluminum-polymer capacitor created by Alphcon Electronics. It is specially formulated with a high-speed version that provides low equivalent series resistance (ESR) and is geared towards medium frequency switching applications. It is widely used in automotive, industrial and consumer applications, and contains a 4V to 10V DC voltage. The RR70G122MDN1PH is an aluminum-polymer electrical component made using component parts that combine electrolytic aluminum foil with polymerized organic materials such as polyphenylene sulfide, polyethylene terephthalate, and ethylene propylene diene. Depending on the technology used, the polymer component parts can consist of a mixture of different materials such as activated carbon, ceramic powder, zeolite, etc. By varying the component parts, the construction can be tailored for a wide range of applications and operating temperature ranges.The operating principle of an aluminum-polymer capacitor is essentially no different from that of any other type of capacitor. It follows the same basic principle of capacitance, regardless of its construction. In an aluminum -polymer capacitor, the electric current is stored in the form of a potential, which consists of a positive plate and a negatively charged plate. These plates are insulated, in the form of a thin dielectric film, by either air or any other insulating material such as paper, mica, ceramic, rubber, plastic, etc. The electric current to the capacitor is then applied across the terminals of the plates using a dielectric material. The dielectric material acts as an insulator between the two plates, so that the potential which is maintained across the positive and negative plates doesn’t dissipate. This potential is the capacitance that is measured as the electric current is maintained within the capacitor.With the RR70G122MDN1PH, it offers an output capacitor design for efficient circuitry, with a wide temperature vertical range due to its 10 x 7 x 8.5mm case dimensions, and a wide capacitance range from 10µF to 1,000µF. This allows for a low ESR and low dissipation factor, in addition to the high ripple current of 185mA at +85°C. It can also be used in various operating temperatures, typically from -55°C to +85°C. Due to these reasons, this capacitor makes an ideal choice for powering digital devices and LED lighting applications. The RR70G122MDN1PH is an affordable solution due to its high-volume production, and can be used in multiple circuits and devices. It boasts an impressive load life, up to 1,000h at +85°C, along with other features such as the Bi-Polar Working Voltage, 6.3V to 16V, allowing it to be used across a wider range of applications with different power requirements.All in all, the RR70G122MDN1PH is a versatile and reliable aluminum-polymer capacitor from Alphcon Electronics, designed for various medium-frequency switching applications. Its low equivalent series resistance, voltage and capacitance range, combined with its flexibility and performance make it an ideal solution for many electronic and automotive systems,where functionality and energy efficiency matter.
