3.3 How to identify the correct components
Resistors:
The resistors are easy to identify by the coloured bands
across the cylindrical body. Using a multimeter it should will
be possible very quickly to identify the different values.
Capacitors:
Take care when identifying the 2 small ceramic or polyester
capacitors. Depending on part availability, 2 or more different
types may be supplied. The 22nF capacitors (C4, C6) may be
marked 22nF, 22n, or 223.
Transistors:
Transistors:
The MOSFET Q2 can easily be identified as it has a large
metal heatsink. Note: Due to part availability, this part may
be substituted for a different but equivalent part number so
the part marking may not necessarily be ‘IRF730’
Diodes:
The four 1N4001 diodes D1-D4 are black and are marked
1N4001. 1N4007 diodes may be supplied instead. They are
identical for this circuit. The other black diode is D5, and
again due to part availability it may be substituted for an
equivalent.
Inductor L1
The inductor is a coil winding on a ferrite core and may or
may not be finished with a heatshrink sleeve depending on
part availability
