Aluminum electrolytic capacitors, also known as electrolytic capacitors, are widely used in electronics and electrical machinery. The UPM1K220MED1TD belongs to a specific type of aluminum electrolytic capacitor, which is also known as an “axial” capacitor. It is a cylindrical anode/cathode and utilizes a foiled paper separator which is soaked in electrolyte.The UPM1K220MED1TD application field is in power supply smoothing and filtering, signal coupling and decoupling, waveform shaping, storage, frequency resonance, automotive ignition, ignition output, and in other applications where a relatively small capacitance, high dielectric strength, low equivalent series resistance(ESR), and a good capacitance tolerance of ±20% is needed.The UPM1K220MED1TD internals are composed of three main components: an aluminum foil anode and cathode, and a foiled paper separator which stores the electrolyte. The separate foils may be wound in a roll, formed into a cylindrical shape, or simply stacked together. By winding and flattening aluminum foil, multiple layers of foil sheet are created which form parallel plates. These plates are separated by a foam insulation layer which is soaked in electrolyte and contained within an aluminum housing.The UPM1K220MED1TD working principle is best explained based on the properties of the anode, cathode, and separator, and understanding how these components interact with the electrolyte. An electrical current is created when the anode and cathode pass through the electrolyte and react with the sodium and chloride ions contained therein. This process generates an electric field, with the voltage between the anode and cathode of the electrolytic capacitor charging or discharging depending on the current flow.The anode layers of this capacitor can be formed into a cylindrical shape, with the anode, cathode and separator inside the same aluminum housing. This allows for a compact design with high power density, making the UPM1K220MED1TD suitable for applications in the automotive and power electronics sectors. The capacitor’s ESR is also low, providing good ripple suppression and improved power supply stability.In conclusion, the UPM1K220MED1TD provides a widely applicable solution for a range of applications. The aluminum electrolyte capacitors features a cylindrical anode/cathode and a foiled paper separator, as well as low ESR, a high dielectric strength, and a good capacitance tolerance. By using this specialized aluminum electrolytic capacitor, engineers are able to benefit from improved power supply stability and ripple suppression.
