APXA6R3ARA821MJC0G Application Field and Working Principle

The APXA6R3ARA821MJC0G is an aluminum-polymer capacitor designed for applications in automotive and industrial systems. This capacitor has a capacitance rating of 6.3µF, an ESR rating of 149 mOhm, and a ripple current rating of 2.6 Arms. It features an on/off pressure contact connection that requires no soldering.

The working principle of the APXA6R3ARA821MJC0G capacitor is based on the theory of electrolytic capacitors. It utilizes a thin film of electrolyte between two layers of electrodes that stores the electrical charge in an electrostatic field. The aluminum-polymer capacitor is constructed with etched aluminum and a polymer bonded dielectric material. This combination ensures a high voltage rating, low ESR, and wide temperature range (-25 to +85 °C).

In automotive systems, the APXA6R3ARA821MJC0G capacitor is used to limit the peak currents that can be drawn from the power supply. This, in turn, helps protect the vehicle\'s electrical system, batteries, and other electronic components during high-amperage events. In industrial applications, the capacitor is used for DC-DC power conversion, as well as for frequency filtering. In both cases, the capacitor\'s low ESR ensures that the power supply remains stable.

The APXA6R3ARA821MJC0G capacitor is packaged in a small, 35-gram package. It is hermetically sealed, which provides protection from dust, moisture, and other environmental conditions. The device also features “snap-on” connections that provide a secure, electromagnetic compatibility (EMC) and reliable electrical connection.

Overall, the APXA6R3ARA821MJC0G aluminum-polymer capacitor is an ideal solution for automotive and industrial applications. Its capacitance rating, ESR rating and ripple current rating make it suitable for various power conversion and filtering requirements. Additionally, its hermetic sealing and snap-on contacts make it reliable, secure and EMC compliant, providing superior electrical and environmental protection.
