SK Series Miniature Aluminum Electrolytic Capacitors
Product Overview
The SK Series capacitors are miniature aluminum electrolytic capacitors designed for high-performance applications. They offer higher ripple current and lower impedance compared to GT and GY series respectively, enabling high ripple current capability through impedance reduction at high frequencies. With a load life of 6,000 to 10,000 hours at 105C, these capacitors are ideal for personal computer and storage equipment, providing the lowest impedance for such applications. They operate reliably in a wide temperature range and are built to last.
