Aluminum-polymer capacitors are electrical components that are part of a larger circuit, typically used to store or filter electrical energy, and this article will discuss the application field and working principle of the specific EEF-SX0D391XR aluminum-polymer capacitor.

Typical aluminum-polymer capacitors are made of a tightly wound aluminum foil, usually the anode, covered with plastic that serves as the dielectric. Electrolytic-type capacitors will also contain an electrolyte, unlike ceramic capacitors. The EEF-SX0D391XR aluminum-polymer capacitor has an aluminum foil as the anode (positive) with an electrolytic layer made of a conductive polymer material serving as the dielectric. This type of capacitor not only has an increased energy density compared to standard aluminum-polymer capacitors but also offers a long-term stability in the range of -55°C to +125°C.

The maximum capacitance of the EEF-SX0D391XR aluminum-polymer capacitor is 1000 μF and its capacitance tolerance is -15%, +10%. It is rated ripple current at 120 Hz and +125°C of 3.5A. Its equivalent series resistance (ESR) is 0.06Ω, its leakage current at +25°C is 5mΑ and its impedance is 5.8 mΩ. The maximum operating voltage is 6.3V and its lifetime is over 1,000 hours at +125°C.

The EEF-SX0D391XR aluminum-polymer capacitor is mainly used in automotive, audio, ventilation and other electronic equipment in order to reduce noise, filter out any spikes and save energy. It can also be used as a power supply capacitor as it can store energy and release it when needed. It is usually used with a dedicated switch and inductor to form an L-C circuit. A switch is used to turn on and off the current flowing through the switch and the inductor, which creates the induction voltage. This voltage is then used to store energy in the capacitor and reduce the voltage ripple.

In summary, the EEF-SX0D391XR aluminum-polymer capacitor is a versatile and highly efficient electrical component and is ideal for a wide range of applications. It can be used to reduce noise, filter out spikes and save energy, as well as being a reliable power supply capacitor. It has a long-term operational stability, even at extreme temperatures, and can handle a variety of ripple currents.
