01EC1577SHG4.7uF450V
Category
The C503212 is a cost-effective aluminum electrolytic capacitor optimized for power supply filtering and EMI suppression in industrial and consumer electronics. With 4.7µF capacitance, 450V rating, and 210mA ripple current handling, it excels in decoupling and filtering applications. Key limitations include ESR sensitivity to frequency and shorter operational lifespan compared to newer technologies. Best suited for medium-frequency power regulation where cost and space efficiency are prioritized over high-frequency performance.
