Type ST 55 °C Strobe-Flash, Long-Life, 360 & 450 V Aluminum
High Energy, Long-Life
Rugged Type ST capacitors can withstand more than
30 million full discharges in typical strobe-lamp
applications—that’s more than ten years’ operation in
emergency vehicles. This exceptional life capability is
also available in screw-terminal and other case styles
and other capacitance values.
The ST’s magic is its ability to handle the spectrum
of currents caused by full discharge at 1 Hz and faster
rates. Because discharge energy is at frequencies from
less than a hertz to thousands of hertz, power loss and
heating are not predicted by the ESR at 120 Hz, and the
open-structure anode foil of Type ST excels at low loss
over the full spectrum.
