Electrolytic capacitors
Electrolytic capacitors are often used to store energy. In
contrast to ceramic capacitors they are polarized. One of
the two leads is marked with a minus sign which indicates
the mounting orientation. The value is given on the casing.
Electrolytic capacitors are available with different voltage sustaining
capabilities. Using an electrolytic capacitor with a voltage sustaining
capability higher than required is always possible.
Transistors
Transistors are current amplifiers which convert low signals into
stronger ones. They have three contacts. As they are polarized, they
have to be mounted in a certain direction.
The BD-types have a flat housing (TO-housing) with the
type designation printed on the front side. The metallic
rear is unlabelled, on the PCB layout the rear is marked by
a thick line.
PCB sockets
The widely spread 2,6 mm model railway connectors fit exactly to the
sockets. These are used for the connection to the voltage supply and to
connected modules or components.
