Aluminum-polymer capacitors are a type of electrolytic capacitor that combines the benefits of both aluminum electrolytic capacitors and film capacitors. They offer several advantages over traditional capacitors, including lower equivalent series resistance (ESR) and higher capacitance values in a smaller package. Their small size and high performance make aluminum-polymer capacitors ideal for a variety of applications. The RNU1E221MDNASQPX is a particularly popular choice within this range of capacitors.

The RNU1E221MDNASQPX is an aluminum-polymer capacitor that features a low ESR and high capacitance value. It has a capacitance of 220 micro-Farads with a maximum working voltage of 10 VDC. Its standard capacitance tolerance is ± 20%, which provides a range of 176 to 264 μF. Its dimensions are 2.5 mm x 7.3 mm x 5.5 mm (0.098 x 0.287 x 0.217 in.) and it has an operating temperature range of -55ºC to +125ºC (-67ºF to +257ºF). It also offers a ripple current rating of 2.46 mA RMS (max).

The RNU1E221MDNASQPX is typically used for applications where a low-profile, high-performance aluminum-polymer capacitor is needed. Such applications include consumer and industrial audio equipment, professional audio, radio interference filters, and automotive sound systems. Additionally, this capacitor is often used in notebook computers, digital cameras, and laptops, as well as in power supplies, USB devices, wireless devices, and computer UPS systems.

This capacitor works by using an electrolyte between two electrodes and a dielectric material to store energy. Specifically, the RNU1E221MDNASQPX uses a thin film of aluminum electrolyte as the dielectric between two electrodes – an anode and a cathode. When a voltage is applied to the capacitor, electrons migrate from the cathode to the anode, creating an electric field in the capacitor. This electric field creates a space where an electric charge can build up and serve as a source of energy.

The RNU1E221MDNASQPX also offers several advantages over traditional electrolytic capacitors. Due to its thin film of aluminum that acts as the dielectric, it offers better thermal stability, higher capacitance values, and lower ESR. These benefits, combined with its small size and high performance, make it a popular choice in an array of applications.
