capacitor a device used to store an electric charge, consisting
of one or more pairs of conductors separated by an
insulator.
cold solder joint a solder connection that exhibits poor wetting and is
characterized by a grayish, porous appearance due
to excessive impurities in the solder, inadequate
cleaning prior to soldering, and/or the insufficient
application of heat during the soldering process
digital multimeter electronic test equipment that can perform multiple
tasks. typically one capable of measuring voltage,
current, and resistance. more sophisticated modern
digital multimeters also measure capacitance,
inductance, current gain of transistors, and/or
anything else that can be measured electronically
,diode a two terminal device that conducts in only one
direction
dual in-line package (dip) a very common IC package with two parallel rows of
pins intended to be inserted into a socket of through
holes drilled in a printed circuit board
engineering notation a floating point system in which numbers are
expressed as products consisting of a number
greater than one multiplied by an appropriate power
of ten that is some multiple of three
fuse a protective device in the current path that melts or
breaks when current exceeds a predetermined
maximum value
led light-emitting diode. an electronic device that
conducts current in one direction only and
illuminates when it is conducting
plastic leaded chip carrier (plcc) a square ic package with leads on all four sides
designed for surface mounting on a circuit board
, printed circuit board insulating board containing conductive tracks for
circuit connections
resistor component made of material that opposes flow of
current and therefore has some value of resistance
resistor colour code coding system of colored stripes on a resistor to
indicate the resistor's value and tolerance
scientific notation numbers entered as a number from one to ten
multiplied by a power of ten
si notation abbreviation of system international, a system of
practical units based on the meter, kilogram, second,
ampere, kelvin, mole, and candela
seven-segment display an array of seven independently controlled light-
emitting diodes (led) or liquid crystal displays (lcd)
elements, shaped like a figure-8, which can be used
to display decimal digits and other characters by
turning on the appropriate elements
small outline ic (soic) an ic package similar to a dip, but smaller, which is
designed for automatic placement and soldering on
the surface of a circuit board
solder metallic alloy of tin and lead that is used to join two
metal surfaces
