Tantalum capacitors are widely used in electronic fields. They are components that store electric energy and release it when needed. CWR19KK685KBFB is a popular model of these devices commonly used in various applications. This article presents the application field and working principle of CWR19KK685KBFB.

The CWR19KK685KBFB tantalum capacitor is a surface-mounted, surface-mount capacitance device which conforms to the US-standard measurements. It is a polarizable double layer type that works on the premise of reverse breakdown voltage. It has versatile features, making it apt for use in many applications, like audio-visual (AV) components, portable telephone equipment, medical equipment and entertainment centers.

This capacitor is designed to operate with a wide range of voltage, from 2.5 to 18V with a capacitance range from 100 to 4700uF. It also has high insulation resistance and low temperature coefficient, making it suitable for temperature-sensitive and high-impedance applications. It can also withstand higher temperatures and continuous ripple currents up to 3.2A.

The working principle of CWR19KK685KBFB informs how the capacitor stores electrical energy. When a voltage source is connected to the two terminals of the capacitor, it stores the electric energy in the form of an electrical field between the two conducting plates. The plates then act as a dielectric medium that prevents the flow of electric current but allows the buildup of charge when energy is applied. This energy is stored as a function of current and time, known as capacitance.

In a Tantalum capacitor, the outer concentric cylinder acts as the anode terminal while the inner cylinder functions as the cathode terminal. Between the two plates is a dielectric material of Tantalum oxide. When a voltage source is connected to the two terminals, the anode receives positive charge and the cathode, negative charge. This creates an electrical field and therefore a capacitance, allowing for electrical energy to be stored and released when required.

In conclusion, CWR19KK685KBFB is a versatile tantalum capacitor with a wide range of applications, including audio-visual components, portable telephone equipment, medical equipment and entertainment centers. It operates with a wide range of voltage and supports high temperatures and continuous ripple currents. This capacitor works on the basis of reverse breakdown voltage and stores electrical energy as a function of time and current. The dielectric material of Tantalum oxide between two plates allows for the build-up of charge when required.
