65863-009LF

65863-009LF is a type of capacitor which belongs to the tantalum (Ta2O5) series. It is mainly used in consumer electronics, such as laptop computers, digital cameras, and other digital products. The main characteristics of this capacitor are its high volumetric efficiency, low ESR, and small temperature coefficient.

The application field of 65863-009LF includes mobile phone, notebook computer, digital cameral as well as other digital consumer electronics. It is widely used for decoupling, filtering, time-delay, smoothing etc. Decoupling is one of the most common application of the capacitor. Its role is to prevent the power supply gap from being affected by the circuit current. When the circuit current changes suddenly, a decoupling capacitor needs to be selected to avoid the power supply voltage from falling or rising suddenly.

The working principle of 65863-009LF is based on the properties of the tantalum capacitor. The real tantalum capacitor is composed of two pieces of metal substrate, lingquin and Ta2O5 dielectric film. When an external voltage is applied to the capacitor, an electric field will be generated between the two metal pieces and the dielectric film, and an electric charge will be formed on the surface of the dielectric film, resulting in a certain capacity. Depending on the material of the dielectric film, the capacitance of the capacitor will vary.

When 65863-009LF is working, the Work Voltage of the capacitor is determined by the material of the dielectric element. The dielectric element is composed of TAV and TA2O5 material, with a total work voltage of 50V. The capacitance of the capacitor is determined by the area of the metal and the TA2O5 material. A larger area leads to a larger capacity, and the minimum capacitance can reach to 0.068uF.

The voltage coefficient of the 65863-009LF is mainly related to the temperature coefficient. The temperature coefficient of the capacitor is given by the following expression: Z = 2S/T, where S is the dielectric breakdown voltage of TAv, and T is the absolute temperature. The higher the temperature coefficient, the smaller the voltage coefficient, so the temperature coefficient must be considered when selecting a capacitor.

In summary, 65863-009LF is an useful capacitor which is mainly used in mobile phone, notebook computer, digital cameral and other digital electronics. It can be used for decoupling, filtering, time-delay, smoothing etc. It has high volumetric efficiency, low ESR and total work voltage of 50V. Moreover, the voltage coefficient and temperature coefficient must also be carefully considered when selecting one.
