Snap-In Aluminum Electrolytic Capacitors
ALC40, +105C
Overview Applications
KEMET's ALC40 Series of snap-in capacitors features the
KEMET's ALC40 capacitors are suited for high reliability
same high ripple currents and long-life characteristics as
and long life applications such as frequency converters,
the ALC10 Series but can operate at higher temperatures.
uninterruptible power supply (UPS) systems and switch
mode power supplies (SMPS). The extended temperature
range allows increased ripple currents at lower
temperatures.
