Electric Double Layer Capacitors (EDLC), also known as Supercapacitors, are energy storage devices which offer combination of the energy capacity and properties of batteries and the power capacity and properties of capacitors. The DGH335Q2R7 from Panasonic Automotive is a part of this technology. This article focuses on the application field and working principle of the device.Application fieldThe DGH335Q2R7 has become a widely-used component in the automotive industry. It has been used to improve energy efficiency and reliability. With its efficient energy storage capacity, the DGH335Q2R7 has become a valuable contributor to vehicles’ electric systems.The scope of application has extended far beyond automobiles. The device can be used in many consumer electronic devices such as mobile phones, tablets and laptops. It is also used in medical equipment, household appliances, and security systems. Moreover, the device has been employed for memory backup and power supply applications.The device\'s extended operating temperature range, as well as its vibration and shock resistance, makes it suitable for a wide variety of applications. Additionally, DGH335Q2R7’s high power density and long lifetime, coupled with its low self-discharge and energy efficiency, make it the preferred choice for any need.Working principleWhen talking about energy storage devices, capacitors and batteries are generally the main technologies used. However, the DGH335Q2R7 is a new device which combines the energy capacity of batteries with the power capacity of capacitors. The device is based on the electrochemical double layer capacitance (EDLC) principle.In this device, two flat, porous electrodes are separated by an electrolyte. The electrolyte provides ions to the electrodes and forms an electric double layer. This double layer creates an electric field between the two charge-storing layers. This field is responsible for storing energy.Unlike regular capacitors, the DGH335Q2R7 is able to store more energy. This is due to its ability to store large amounts of ions from the electrolyte between the two electrodes. As a result, the overall capacitance of the device is higher and more energy can be stored.The DGH335Q2R7 also features high energy density, meaning it can store more energy in a smaller volume. This increases the overall efficiency of the device and helps keep the cost down.Moreover, the device is able to operate over a wide temperature range. Additionally, it features a long cycle life and low self-discharge rate. This means that it is able to consistently provide power even after long periods without being used.ConclusionThe DGH335Q2R7 from Panasonic Automotive is a type of energy storage device which is part of the electric double layer capacitor (EDLC) family. The device is based on the electrochemical double layer capacitance principle and it offers several advantages over traditional capacitors and batteries. Its extended temperature range, vibration and shock resistance, high power density, low self-discharge rate, and long lifetime make it a valuable asset to the automotive industry, as well as other consumer electronic and medical applications.
