Description

Electric Double Layer Capacitors (EDLC) and Supercapacitors have become increasingly popular over the years as they offer many advantages over standard batteries. One of the most popular models in this category is the CPX3225A752D. This EDLC/Supercapacitor is well-known for its impressive performance and wide range of applications. In this article, we’ll look at the application fields and working principle of the CPX3225A752D.Application FieldsThe CPX3225A752D EDLC/Supercapacitor is primarily used in energy storage applications. It has the highest energy density of any EDLC in its class, which makes it especially suitable for applications where energy density is a priority. It is ideal for UPS (Uninterruptible Power Supply) systems, medical devices, batteries and other high power density applications. The CPX3225A752D is also often used in automotive systems, such as electric cars, hybrid vehicles, and fuel cell cars. In addition to its energy storage capabilities, the CPX3225A752D also has a wide range of other applications. It can be used in telecommunications systems, including wireless access points, base stations, and other related infrastructure. Other applications include wireless networks, data centers, and solar energy systems. Working PrincipleEDLCs/Supercapacitors work by storing energy in the form of an electric double-layer capacitance. This is done using a porous electrode and a special type of electrolyte. The porous electrode serves as an interface between the two electrolytes, allowing ions to pass between them.When an electric potential is applied across the electrodes, ions from one of the electrolytes are drawn to the opposite electrode, creating a double layer of charge. This is known as the electric double-layer capacitance. This double layer of charge functions as a capacitor, storing energy and allowing for electrical current to flow through the device. The CPX3225A752D has a number of advantages over other EDLCs/Supercapacitors. It has a very high energy density, which allows for greater power delivery to a system. It also has a much longer life than most other EDLCs/Supercapacitors, which makes it ideal for long-term energy storage applications. Lastly, it is also capable of charging and discharging at a much higher rate than most other EDLCs/Supercapacitors.ConclusionThe CPX3225A752D is one of the most popular Electric Double Layer Capacitors (EDLC) and Supercapacitors on the market today due to its impressive performance and wide range of applications. It has a very high energy density, making it particularly suitable for high-power density applications. Additionally, it has a long lifespan and is capable of charging and discharging at a much higher rate than other EDLCs/Supercapacitors. All of these features make it an ideal choice for energy storage applications.

Features

   1. Large discharge current and super rapid charging achieved by low internal resistance

Reduced internal resistance to 25 ohms, one-third that of the conventional EDLCs, allows discharge current of up to several tens of mAs and rapid charging within a few seconds.

   2. Chargeable by slight power, thanks to low leak current

Reduced leak current to about 10 nA level, approximately one-tenth that of the conventional EDLCs, allows sufficient charging with several micro Watts from a slight energy harvestingpower source.

Application

   1. Electric storage device for energy harvesting

   2. Power source or Electric storage for Wireless Sensor Network, RFID tag, ..

   3. Power source or Electric storage for Contactless IC card, multi-functional IC card

   4. Instant back-up power source for memory

   5. Smoothing peak current loads

                                                                                  └── 10Ω resistor (damping matching)

Design considerations

   1. Soldering conditions:

        - Reflow peak temperature ≤260°C (within 10 seconds)

        - Manual soldering requires a soldering iron ≤350°C (within 3 seconds)

   2. Mechanical stress:

       - PCB bending radius>5mm

       - Avoid installation in the stress concentration area at the edge of the board
