Aluminum - Polymer Capacitors are widely used in a broad range of applications, including energy storage, power distribution, and signal processing. The APXE6R3ARA221MF61G is a widely used Aluminum - Polymer capacitor with excellent performance, high reliability, and fairly low cost. This technology is beginning to replace tantalum capacitors for certain duties and applications due to their superior capacitance, frequency response, and robustness. With increasing demand for higher power applications such as those found in hybrid and electric vehicles, the use of Aluminum - Polymer capacitors is becoming more popular.

The APXE6R3ARA221MF61G Aluminum – Polymer capacitor is designed for general-purpose, non-critical applications that require low ESR, high ripple current and low parasitic inductance. It is suitable for use in frequency converters, motor drives, and high-frequency oscillators. It has a wide operating frequency range of 0.5 Hz up to 10 kHz, and its low ESR performance make it an excellent choice in high frequency applications.

The APXE6R3ARA221MF61G consists of an aluminum housing with a corrosion-resistant, normally closed contacts. The capacitor itself is constructed with an anode formed of Aluminum foil, and a cathode formed of highly conductive porous polymer, combined with a dielectric medium. This combination provides excellent capacitance which is independent of temperature and frequency, as well as a low ESR. As with most Aluminum-Polymer capacitors, the ESR is lowest over the temperature range from -40°C to 85°C. The device has a fairly low leakage current, and it is capable of handling high ripple currents.

In terms of its working principle, the APXE6R3ARA221MF61G is constructed in such a way that the two electrodes form a three-dimensional double layer at the interface between the aluminum and the polymer. This double layer stores electric charges and can provide a wide range of capacitance values ranging from <1nF to over 1000µF. The device’s capacitance is also temperature-compensated, meaning it will retain its capacitance over a range of operating temperatures. The capacitance value varies less than 0.01% from -40°C to 85°C.

In summary, the APXE6R3ARA221MF61G Aluminum - Polymer capacitor is a great option for applications that require extended temperature performance, high capacitance values, low ESR, and high ripple current. It is a reliable and cost-effective choice for many applications, including motor drives, frequency converters, and high-frequency oscillators.
