01EC0069SHG4.7uF400V
Category
The KNSCHA 01EC0069SHG4.7uF400V is a cost-effective aluminum electrolytic capacitor designed for power supply filtering and decoupling in consumer electronics and industrial systems. With a 4.7µF capacitance, 400V rating, and 150mA ripple current, it excels in stabilizing voltage in switch-mode power supplies and motor drives. Key limitations include ±20% tolerance and moderate thermal performance, requiring careful layout planning. Ideal for applications prioritizing cost efficiency over ultra-precision requirements, particularly in environments with moderate thermal conditions.
