Aluminum Electrolytic CapacitorsAluminum electrolytic capacitors are widely used in industrial and consumer applications due to their high energy storage capability and relatively low cost. The UPT2W680MHD is a particular type of aluminum electrolytic capacitor, distinguished by its name indicating its case size, capacitance in micro Farads (μF), and operating voltage.When the UPT2W680MHD is used within a circuit, the capacitor functions as an energy storage device capable of filtering and smoothing voltage signals as well as filtering high frequency noises. The combination of these characteristics makes the UPT2W680MHD well suited for use in applications requiring a combination of low equivalent series resistance (ESR) and a high capacitance value. In particular, the UPT2W680MHD is often identified as a good choice for regulating the voltage in a wide variety of devices, including monitors, DVD players, computers, and digital SLRs.The name UPT2W680MHD indicates the capacitor’s case size, which is referred to as the “UPT2W” attribute. The “UPT2W” refers to the rated footprint size of the case, specifically, 6.8mm by 8.0mm. The “680” refers to the micro farad capacitance value, implying that the devices capacitance is 680μF. Finally, the “MHD” refers to the rated operational voltage of the device. The “MHD” could be interpreted as either “25V” or “35V”, as the UPT2W680MHD is available in both voltages.All aluminum electrolytic capacitors share a similar construction in which two aluminum foils are separated by a dielectric oxide layer. Together this combination of layers creates the capacitor plate, which is then wound in a coil pack, dipping it into a highly conductive electrolyte solution to form a self-healing capacitor. The aluminum foil acts as the positive plate, while the negative plate is contained within the electrolyte solution.The combination of the dielectric oxide layer and the electrolyte solution provide the capacitor with its large capacitance ratings and long operating life. The dielectric oxide layer acts as the insulator between the positive and negative terminal, while the electrolyte solution acts as both the electrical conductor and the lubricant needed to keep the oxide layer from breaking down due to thermal stress.The UPT2W680MHD is ideal for applications requiring a combination of high capacitance and low ESR values, including power supplies, automotive electronics, and streaming video devices. Due to its 6.8mm by 8.0mm case size, the UPT2W680MHD can easily be integrated into most circuit boards, providing increased flexibility for designers. In addition, the UPT2W680MHD also provides engineers with a reliable solution at a relatively low cost.
