Solid State Drives/High Energy Applications
Polymer Electrolytic (KO-CAP
®
), 6.3 – 35 VDC
Overview
The KEMET Organic Capacitors (KO-CAP) are preferred
solutions for applications requiring power loss protection
(hold-up) or maximum power eciency of a circuit when
board space is limited. Desired benets include high
energy density, stable capacitance with applied voltage
and temperature, and no aging effects. The conductive
polymer cathode of these solid electrolytic capacitors
provide very low ESR and higher capacitance retention at
high frequencies. Unlike liquid electrolyte-based capacitors,
KEMET polymer capacitors have a very long operational
life and high ripple current capabilities. Capacitors from
T520, T521, and T523 series are commonly used in these
applications. The T545 and T548 were introduced to meet
specic needs for a subsegment of solid state drives.
