Category
This 33uF/50V aluminum electrolytic capacitor provides stable energy storage with 150mA ripple current handling, optimized for power supply filtering in motor drives and inverters. Its compact D5xL11mm package ensures space efficiency in industrial automation systems, while thermal management requires careful PCB layout to maintain ESR performance. The ±20% tolerance limits precision applications but offers cost advantages in non-critical filtering roles.
