Resistance networks
In resistance networks several resistors are integrated. The
number of the integrated resistors varies depending on the
design. One side of the resistors is commonly taken out of the
network, the other side seperately for every resistor. The
common connection of the resistors is marked which is also
shown on the PCB print.
Capacitors
Among other things capacitors are used for filtering
interference voltages or as frequency determining parts.
Ceramic capacitors are not polarized, for that reason their
mounting orientation is of no importance. Normally they are
marked with a three-digit number which indicates the value
coded.

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.
