Tantalum capacitors are widely used in electronic circuit applications both in industry and in hobbyist level design. They are preferred for their high stability, low impedance and extremely low cost when compared to other electrical components. The TAJW686M004RNJ, in particular, is a surface-mounted tantalum capacitor of an axial leaded type.The common application fields of the TAJW686M004RNJ are telecommunications, computer systems and avionics, as the device requires only a minimum amount of space on the board and provides low ESR (equivalent series resistance). Additionally, the device is resistant to most organic solvents, can operate over a wide temperature range and is suitable for severe environmental conditions.The TAJW686M004RNJ operating principle is simple. When voltage is applied to its two terminals, electrons flow from the negative to the positive terminal. During this process, an electric field is created between the two terminals and this field creates a dielectric barrier in the form of an oxide film on the surface of the tantalum. As the charge builds up on this barrier, the device accumulates what is known as a depletion layer as well as additional electrons. The depletion layer ensures that the device can handle higher voltages with little to no distortion in the electric field.In order to achieve greater stability, the TAJW686M004RNJ is internally polarized, which means that when the capacitor is installed, one terminal must be connected to the positive voltage while the other one is connected to negative voltage of the same magnitude. This significantly reduces the polarization effects and minimizes the reverse leakage current when compared to comparable non-polarized capacitors.Furthermore, the TAJW686M004RNJ is a surface-mounted device (SMD), meaning its design features an extended thin film that adheres to other components on the circuit board via a process known as soldering. This eliminates the need for extra solder and makes it easier to replace any one failing component in a Circuit Board.In conclusion, the TAJW686M004RNJ is a tantalum capacitor suitable for challenging industrial applications, offering superior stability and wide temperature range. Thanks to its extended thin film design and internal polarization, it can tolerate large voltage differences with minimal distortion and leakage, making it a great choice for any system requiring reliable and small-sized components.
