EEF-KX Series SP-Cap™ Polymer Aluminum Electrolytic Capacitors

Panasonic's EEF-KX series surface-mount specialty conductive polymer aluminum electrolytic capacitors feature a high endurance of 5,500 hours at +125°C, enabling use in applications with exceptionally long life. The EEF-KX series’ high-temperature, long-life parts are achieved using Panasonic’s proprietary conductive polymer formation and manufacturing process technology.

The EEF-KX series capacitors feature ultra-low ESR (9 mΩ max.) and high durability under high-temperature and high-humidity conditions of 1,000 hours at +85°C/85% in a damp-heat steady state, providing SP-Caps with large capacitance characteristics for harsh industrial applications.

Panasonic’s EEF-KX series redefines the term “specialty” capacitor by combining all these specifications in a package with only a 1.9 mm maximum height. Space-saving, high-reliability capacitors with a long lifetime and resistance to high humidity and large capacitance are the requirements for the stabilization of power supply circuits.
