Aluminum electrolytic capacitors are widely used in electronics applications due to their high capacitance, low cost, and low leakage current. The UHE1H681MHD aluminum electrolytic capacitor is a highly reliable, low impedance radial device from TDK. It offers excellent performance for buffer and smoothing applications as well as general buffering and bypassing use.

The UHE1H681MHD has an impressive maximum product operation temperature of 105°C with a voltage rating of 6.3V. It has an Electrolytic (wet) type and a maximum rated ripple current of 600mA. Its dimensions are 6.3mm (L) x 6.6mm (W) x 8.2mm (H) making it suitable for use in a variety of applications.

The working principle of this aluminum electrolytic capacitor is based on electrolytic ion migration. When a voltage is applied across a pair of metallic electrodes that are separated by an insulating material, current flows due to electrostatic forces. This current can cause electrolyte ions to move from one electrode to the other. The result is an effective capacitance that is determined by the size of the plastic film and the number of ions available.

The UHE1H681MHD demonstrates high reliability in a variety of electronic circuits for buffer and smoothing applications. These applications include voltage doublers, rectifiers, bypassing, noise reduction, voltage divisions, 1/f noise suppression, and frequency filters. This capacitor is also used in critical high-reliability functions such as charge voltage protection, load sharing, and temperature compensation.

The UHE1H681MHD is also a popular choice for power supply circuits where long-term operation and current minimization are desired. In particular, its low impedance ensures the capacitor can supply sufficient current when required by the circuit without undesirable losses. This makes it suitable for use in switching power supplies, DC/DC converters, and battery management systems.

The UHE1H681MHD aluminum electrolytic capacitor’s reliable and low impedance characteristics make it an ideal choice for power-supply and buffer & smoothing applications. Its long-term stable operation and excellent ESR and leakage characteristics ensure an efficient and reliable performance for a wide range of voltage rated circuits.
