Aluminum electrolytic capacitors are a very important component in today\'s electronic products. They are mainly used for signal coupling, filtering, oscillation, bypass, surge absorption, and circuit timing. In high-frequency circuits, they can reduce the disturbances of other signals and can also be used to filter high-frequency noise.The UVK1H221MPD1TD is an aluminum electrolytic capacitor with a rated voltage of 180VDC and a rated ripple current of 0.51A. It has a very low equivalent series resistance (ESR) and high ripple current ability. The capacitor has an operating temperature range of -40°C to +105°C, and a shelf life of 10 years when operating at 21°C and 72% relative humidity.The main component of aluminum electrolytic capacitors is the anode, which is mainly made of an aluminum foil, and a cathode made of a sintered manganese dioxide (MnO2) powder layer. In the anode of the UVK1H221MPD1TD aluminum electrolytic capacitor, there is an electrolyte which acts as an insulating barrier between the anode and the cathode and provides it with a high dielectric strength.The working principle of the UVK1H221MPD1TD is based on the formation of anodic and cathodic layers, which are separated by an electrolyte. When a voltage is applied across the capacitor, positive charge accumulates in the anode, while negative charge accumulates in the cathode. This creates an electric field between the two layers, which stores energy. When the voltage is removed, the energy is discharged, generating a current.The main application field of the UVK1H221MPD1TD is for audio, instrument, control and power applications. The capacitor is most commonly used for ripple current absorption, and for providing noise reduction and power smoothing in electronic circuits where a high ripple current is required. It is also suitable for power factor correction, timing and current filtering, such as in high-frequency power supplies and motor drives.The UVK1H221MPD1TD provides a high level of reliability and long life, even when operating at temperature extremes and in harsh environments. This combined with its high ripple current ability and low ESR, makes it a suitable choice for applications that require high-quality and reliable performance.
