Electrolytic capacitors 
Electrolytic capacitors are often used to store energy. In
contrast   to   ceramic   capacitors   they   are   polarized.   The
value is given on the package.
Electrolytic capacitors  are available with  different voltage
sustaining capabilities. Using an electrolytic capacitor with
a   voltage   sustaining   capability   higher   than   required   is
always possible. 
Diodes 
Diodes allow the current to pass through in one direction
only   (forward   direction),   simultaneously   the   voltage   is
reduced  by 0,3 to  0,8 V. Exceeding of the limit  voltage
always will destroy the diode, and allow current to flow in
the reverse direction. 
The diode type is printed on the package. 
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) have a
package in form of a half zylinder (SOT-package). 
The three pins of bipolar transistors (e.g.  BC types) are
called basis,  emitter  and  collector  (abbreviated  with the
letters B, E, C in the circuit diagram). T
PCB sockets
The widely spread 2.5 or 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.
