EEF-KX Conductive Aluminum Electrolytic Capacitors

Panasonic EEF-KX Conductive Aluminum Electrolytic Capacitors feature a high endurance of 5500 hours at +125°C, enabling use in applications with exceptionally long life. These high-temperature, long-life capacitors utilize a conductive polymer formation and manufacturing process technology, providing high durability under high temperature and high humidity conditions. The EEF-KX series offers a maximum equivalent series resistance (ESR) range of 3mΩ to 15mΩ, a capacitance range of 120μF to 470μF, and a maximum height of 1.9mm. Panasonic EEF-KX Capacitors are suitable for servers, industrial equipment, power management systems, and other applications.
