DK-6R3D474T

The DK-6R3D474T is one of the most widely used Electric Double Layer Capacitors (EDLC) or Supercapacitors. The component is a solid-state capacitor that combines an electric double layer of activated carbon and an electrochemical capacitor, often referred to as an “ultracapacitor”. This allows the device to store a relatively large amount of charge in a small package, enabling long-term storage and rapid discharging of energy. The DK-6R3D474T is typically used for energy storage since it has a long life-span, low self-discharge, low noise, good vibration resistance and a wide operating temperature range (-40°C to +85°C).

The DK-6R3D474T is primarily used in applications such as regenerative braking, automotive start-stop systems, renewable energy systems, and uninterruptable power supplies. The component offers several benefits over traditional capacitors in that it has a higher energy density due to its unique construction and electrode material. Additionally, its resistance to electrical noise is higher than that of traditional capacitors.

The specific working principle of the DK-6R3D474T is based on the physical properties of activated carbon and the physical chemistry of electrolytes. Activated carbon acts as an adsorption material, and its internal pores interconnect to form a capacitive structure. When a voltage is applied to the device, the electrolyte will begin to absorb ionic species from the surface of the activated carbon, forming an electric double layer. The charge stored in the electric double layer will be applied in opposition to the applied voltage, resulting in a capacitance . The capacitance of this device ranges from 1.7V to 3.5V depending on the size of the device and the specific type of electrolyte used.

In addition to energy storage applications, the DK-6R3D474T is also widely used in RF communications as a reset switch or noise filter. In these applications, the capacitor acts as a high pass filter, blocking out low frequency signals and allowing higher frequency signals to pass. Another application for the DK-6R3D474T is in surge suppressors, where the device acts as a short buffer, limiting the peak voltage that a downstream circuit can reach.

Overall, the DK-6R3D474T is an excellent choice for a wide variety of applications due to its high energy density, long life-span, low self-discharge, low noise, and good vibration resistance. The component offers a reliable and cost-effective solution for energy storage and other applications that require an electric double layer capacitor or an ultracapacitor.
