application
Basic design
Smoothing, energy storage, or pulse opera-
tion in telecommunication demanding power
supplies, process control, AC-motor control,
traction and welding.
The ALS42/43 series of screw terminal
capacitors feature the same high ripple
currents and long life characteristics as the
ALS32/33 series but can operate at higher
temperatures. They are similarly suited for
high reliability and long life applications
such as frequency converters, UPS
systems and switch mode power supplies,
but the extended temperature range
allows increased ripple currents at lower
temperatures.
