For the Human Body Model, the current limiting
resistor (R
) and the source capacitor (C
) are
1.5k
an 100pF, respectively. For IEC-1000-4-2,
the current limiting resistor (R
) and the source
capacitor (C
S
) are 330
an 150pF, respectively.
The higher C
value and lower R
value in the
IEC1000-4-2 model are more stringent than the
Human Body Model. The larger storage capacitor
injects a higher voltage to the test point when SW2
is switched on. The lower current limiting resistor
increases the current charge onto the test point.

EIA STANDARDS
The Electronic Industry Association (EIA)
developed several standards of data transmission
which are revised and updated in order to meet
the requirements of the industry. In data
processing, there are two basic means of
communicating between systems and components.
The RS-232 standard was first introduced in
1962 and, since that time, has become an
industry standard.
The RS-232 is a relatively slow data exchange
protocol, with a maximum baud rate of only
20kbps, which can be transmitted over a
maximum copper wire cable length of 50 feet.
The
SP207EH
through
SP213EH
Series of data
communications interface products have been
designed to meet both the EIA protocol
standards, and the needs of the industry.
