Introduction•An electronic component is a basic electronic element usually
packaged in a discrete form with two or more connecting leads or
metallic pads.
•Components are intended to be connected together, usually by soldering
to a printed circuit board, to create an electronic circuit with a particular
function (for example an amplifier, radio receiver, or oscillator).
•Components may be packaged singly (resistor, capacitor, transistor,
diode etc.) or in more or less complex groups as integrated circuits
(operational amplifier, resistor array, logic gate etc.)

Capacitor ratings
Physical size of capacitors is related to voltage handling ability – WVDC – working voltage DC
Temperature coefficient may also be important – can be + or – or nearly zero
Temperature coefficient depends upon dielectric material

Capacitor handling and installation
Most capacitors are not polarized and may be installed in either
direction.
Electrolytic capacitors ARE polarized and MUST be installed with
proper polarity, else catastrophic failure!
Capacitors are not generally susceptible to ESD damage, so special
precautions are not required.
Mechanical stress due to lead bending should be minimized.

Inductor ratings
Wire gauge and physical size of the coil determine the current handling capacity.
Core material will have a temperature dependence. Air is best, followed by iron powder, then ferrites.

IC handling and installation
ICs are polarized and must be installed with correct
orientation. Observe pin 1 location on sockets or circuits.
Treat all ICs as if they are very susceptible to ESD damage
(very many actually are), so rigorous precautions should be
taken.
Leads generally should not be bent.

Electrostatic Discharge (ESD) Protection
Ground your work surfaceUse an anti-static mat
Ground your tools (i.e., soldering iron)Many irons are constructed with a grounded tip
Ground yourselfUse a wrist or ankle strap, but always include a series
resistor of high value to avoid any shock hazard.
Touch a grounded object before handling static sensitive components.
