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.
BC-Types have a housing in form of a half cylinder (SOT-
housing). The cross section is shown in the PCB layout
which determines the mounting orientation.
The transistors IRLU 024N 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.
