This is an Aluminum Electrolytic Capacitor manufactured by SamYoung. The letters TLA450VS330M35*30_VS indicate that it is a leaded 330µF ±20% 450V with a through-hole, 35 x 30 mm RoHS design. This type of capacitor is commonly used in DC link circuit applications such as motor drives, renewable energies, inverters, and variable speed drives, due to its high ripple current, and long life expectancy. This type of capacitor is also suitable for switch-mode power supplies, lighting, and UPS systems because of its nice low ESR (Equivalent Series Resistance), as well as its low leakage current.
