Parts or Components in Electronics
:
Here are circuits made of
Resistors, Capacitors and Inductors
which are passive components.
Crystals, Thermistors, Varistors,
Variable Passive RLC are also Passive
Parts.
Electronics
Work Bench
Some circuits documented from my
design note book are here with the
editable schematics.Zeners, Diodes,
NPN-PNP Transistors, FET, MOSFET, SCR,
Triacs are all discrete active
devices. ICs and Hybrid Modules
are made of many discrete and
passive components.
FET
Current Source and MOSFET
In the Integrated Circuits or ASICs,
all parts even passives are derived on
the Silicon Wafer. In Hybrid Modules
the construction uses SMD or Tiny Chip
components interconnected in a small
ceramic PCB and Hermetically Sealed if
needed.
Parts like Switches, Connectors,
Relays and PCBs are ElectroMechanical
parts. Nuts, Bolts, Screws, Cabinets
and enclosures are Mechanical parts.
Constant
Current Source LED Drive
For a Systems Integrator or Control
Panel Designer, the Timers,
Controllers, PLC which are Electronic
Products become Components or Modules
along with Contacters, Current
Transformers, AC-DC Drives etc.
Simple
High speed data switch
Components have to be wired up on
boards while designing or testing
circuit blocks or concepts. Some
examples of these are shown below.

Bread Board -
This is a reusable gadget like a
connector, works like an IC base,
only that the connectors in this are
very long lasting. you can just plug
in the components and connect using
thick pre-tinned single strand wire.
Big pins can ruin the sockets and
power circuits. Levels > 200mA or
> 24V could be avoided on these
boards.

Electronics Index of J. B. Calvert
General Purpose PCB -
This is a PCB that is available is
some shops, they are known as
"General Purpose Prototyping Board".
They have to be soldered and some
tracks cut with tool-knife. Power
circuits also can be built with wire
reinforcements and RF circuits too
if you plan the layout first on
paper.
SchmartBoard -
This is a new innovation SchmartBoard,
see this link for some ideas see Circuits
Specialists too.
