Nichicon UCN Long Life Aluminum Electrolytic Capacitors

Nichicon UCN Long Life Aluminum Electrolytic Capacitors are high-reliability, surface-mount components engineered for demanding environments, particularly in automotive and industrial applications. These capacitors offer a significant improvement over the previous UCH series, delivering up to 50% more capacitance and extending operational life from 2000 to 3000 hours at elevated temperatures of +125°C. Designed to meet AEC-Q200 standards, the Nichicon UCN series features low ESR, high ripple current capability, and a wide operating temperature range from -40°C to +125°C, ideal for electronic control units (ECUs), infotainment systems, and LED lighting modules. The compact size options and compliance with RoHS directives also support automated assembly processes, while the strict leakage current specifications (especially at 16V) address the growing demand for low standby power in modern electronics.
