Passive
components, especially capacitors, are today undergoing constant
development and so make an indispensable contribution to technical
progress in electronics. Every day we use innovative technical
solutions in communications, in transport, medical technology and for
leisure-time activities. An increasing number of new functions are
controlled, steered or even just made possible by electronics.
One of the most recent innovations in the field of passive components
is the electrochemical double layer capacitor - the SuperCapacitor from
Wima. From about 10 up to several thousand farad (F) values are
housed in one case (Figure 1). A 100 F model, for example, is
approximately the size of a match-box, and this capacitance would
correspond to the impressive volume of 100 million parallel connected
standard polyester film capacitors with an individual capacitance of 1
mF each! With the SuperCapacitor, despite the limitations of its low
maximum operating voltage of 2,5 V, several units can be built up to an
enormous capacitance of the desired voltage rating by connecting them
in series or parallel (cascade).
