Category
The KNSCHA 01EC3470 is a cost-effective aluminum electrolytic capacitor designed for power supply filtering in consumer electronics and industrial applications. With 220µF capacitance, 50V rating, and 350mA ripple current handling, it supports basic filtering in standard power systems while extended use in motor drives and inverters requires careful thermal management. Key limitations include moderate tolerance and sensitivity to environmental factors during storage and soldering.
