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.
Opto couplers
Opto couplers are ICs, which work similar to laser beam switches. They
combine in one housing a light emitting diode and a photo transistor. Their
task is the transmittion of information without galvanic connection. They are
in a DIL-housing with at least 4 pins.
Voltage regulators
Voltage regulators are ICs, which convert a variable, non
regulated input voltage in a constant output voltage. They
are produced in transistor packages with three connecting
pins for input, output and earth.
The package forms of voltage regulators depend on their
type. In use are voltage regulators in SOT packages (half
cylinder shaped) and in flat TO packages.
Terminal strips
Terminal strips are solder-in screw-type terminals. They provide a
solder-free and safe connection of the cables to the circuit, which can
still be separated any time.
