Electric Double Layer Capacitors (EDLC) and Supercapacitors are two very different types of energy storage solutions that have been around for quite a while. Both are based on similar principles, but they have very different applications and capabilities. In this article, we will discuss the DX-5R5V224U application field and working principle, which is an Electric Double Layer Capacitor (EDLC). The Electric Double Layer Capacitor (EDLC) is a type of capacitor which utilizes a thin dielectric material known as a “dielectric”. This dielectric material is sandwiched between two metals plates. When a voltage is applied across the plates, the molecules of the dielectric become polarized, forming a double layer at the surface of each plate. This double layer of polarized molecules creates a high-capacity electric storage system, making EDLC capacitors ideal for applications that require large amounts of energy storage in a very small space.The DX-5R5V224U is a EDLC capacitor manufactured by Vishay Semiconductor. This device has a capacitance of 5.5 Farads in a case size W12.5 x L12.7 x H0.76mm. It also has a nominal voltage rating of 2.5V and a rated ripple current (tenth of peak rated) of 5A. The operating temperature range for the device is -40 to +85°C. The unique advantage of the DX-5R5V224U is its extremely low profile and small size in combination with its low equivalent series resistance (ESR). This makes the device especially suitable for high frequency inverters, such as one-chip motor drivers and inverter applications. It allows for a much higher switching frequency than traditional a capacitor, resulting in greater efficiency and power delivery. In addition, the low ESR of the DX-5R5V224U significantly improves the overall reliability and performance of the applications in which it is used.The working principle of EDLC capacitors is based on the separation of charges between two thin, parallel dielectric films or layers. When a voltage is applied, opposite charges are attracted to each side of the film and accumulate at the interface between the two layers. This creates an electric double layer, hence the name Electric Double Layer Capacitor (EDLC). The accumulation of opposite charges creates an electrostatic field between the two layers that stores energy. In essence, the EDLC capacitor acts like a pair of electrochemical plates separated by a thin membrane, which can store large amounts of energy within a small space. As a result, a single EDLC can store up to 1,500 times more energy than a conventional aluminum electrolytic capacitor in the same amount of space. The ability of EDLCs to store energy at high temperatures is another advantage over aluminum electrolytic capacitors. EDLC capacitors are able to maintain their high capacitance values even when subjected to extreme temperatures. This makes them ideal for use in automotive, telecommunication and medical device applications, which often require high temperature operation. Overall, the DX-5R5V224U is a compact and reliable EDLC device that is ideal for applications that require a very low profile and low equivalent series resistance (ESR). This device offers high energy storage capacity and low temperature dependency in a small package, making it perfect for high frequency inverters and one-chip motor drivers.
