Specification

SEODescription

The RX71C4 electrolytic capacitor is a high-performance component designed for demanding industrial applications, featuring a 105°C high-temperature tolerance and a robust 10,000-hour lifespan under rated conditions. This capacitor operates within a wide voltage range of 6.3V to 450V, making it suitable for power supplies, motor drives, and automation systems. Its durable construction ensures stability in harsh environments, supporting industrial equipment like PLCs, inverters, and renewable energy systems. Key advantages include exceptional heat resistance, low ESR (Equivalent Series Resistance), and compliance with AEC-Q200 standards for reliability. However, its larger physical size compared to standard capacitors may limit use in space-constrained designs. The RX71C4 excels in automotive electronics, industrial machinery, and renewable energy applications where extended operational life and high-temperature resilience are critical.
