Category
The KNSCHA 01EC1404 is a cost-effective aluminum electrolytic capacitor optimized for power supply filtering and decoupling. With 2.2µF capacitance, 400V rating, and 55mA ripple current handling, it serves basic power stabilization in DC-DC converters and motor control. Extended applications include audio systems and renewable energy storage where its -55°C to +105°C operating range and 6Ω ESR provide reliable performance. Designers should prioritize thermal management and correct polarity during soldering, while alternative selection requires matching ESR, capacitance, and voltage parameters.
