EEF-KX Conductive Aluminium Electrolytic Capacitors

Panasonic EEF-KX Conductive Aluminum Electrolytic Capacitors feature a high endurance of 5,500 hours at +125°C, enabling use in applications with exceptionally long life. These high-temperature, long-life capacitors have a conductive polymer formation and are manufactured using process technology, which provides 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.
