Transistors
Transistors are current amplifiers which convert low signals into
stronger ones. There are several types in different package forms
available. The type designation is printed on the component.
Transistors for a low power rating (e.g. BC types, BS
types) have a package in form of a half zylinder (SOT-
package).
The three pins of bipolar transistors (e.g. BC, BD and BT
types) are called basis, emitter and collector (abbreviated
with the letters B, E, C in the circuit diagram).
Integrated circuits (ICs)
Depending on the type, ICs fulfil various tasks. The most
common housing form is the so-called "DIL"-housing, from
which 4, 6, 8, 14, 16, 18 or more "legs" (pins) are
arranged along the long sides.
ICs are sensitive to damage during soldering (heat,
electrostatic charging). For that reason in the place of the
ICs IC sockets are soldered in, in which the ICs are
inserted later.
Microcontrollers
Microcontrollers are ICs, which are individually programmed for the
particular application. The programmed controller are only available
from the manufacturer of the circuit belonging to it.
