APPLICATIONS
The power capacitor is used in vehicles for stabilizing the 12 Volt supply and
support for car audio amplifiers, if fast and temporary high currents are required.
The power capacitor can compensate short-term power peaks on the on-board
electrical system for low and powerful bass operations.
The use of the power capacitors results in a considerably improved power
expansion of the amplifier.
Car audio amplifiers require very high current peaks for a proper operation.
Conventional car battery are not designed to deliver additional power supply
to car audio amplifiers.
Another feature of this power capacitor is to filter car AC voltage included by
the amplifier power supply. This can cause audible interferences in the audio
signal.
