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
S
)
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.
