Panasonic’s Newest High-Reliability SP-Cap Capacitors

Extremely Durable Under High Temperature and High Humidity Conditions, Long Product Life, and Ultra-Low 9 mΩ Max. ESR

Panasonic EEF-KX Series Surface Mount Specialty Conductive Polymer Aluminum Electrolytic Capacitors feature high endurance of 5,500 hours at 125°C, which enables use in applications with exceptionally long life. Achieved by using Panasonic’s proprietary conductive polymer formation and manufacturing process technology, the EEF-KX Series offers new high-temperature long-life parts.

Panasonic’s EEF-KX Series Capacitors provide ultra-low 9 mΩ max. ESR and high durability under high temperature and high humidity conditions of 1,000 hours at 85°C/85% in a damp-heat steady state. At the same time, providing SP-Caps with large capacitance characteristics makes them ideal for harsh industrial applications. 

Combining all these specifications in only a 1.9mm maximum height, Panasonic’s EEF-KX Series redefines the term “Specialty” Capacitor! Space-saving, high-reliability Capacitors with a long lifetime and resistance to high humidity and large capacitance are the requirements needed for the stabilization of power supply circuits.
