The load, due to a single pulse at
which chip resistors fail by going
open circuit, is determined by
shape and time. A standard way
to establish pulse load limits is
shown in Table 1.
With this test, it can be
determined at which applied
voltage the resistive value
changes about 0.5% of its nominal
value under the above mentioned

pulse conditions. Fig. 11 shows
test results for the size 1206 chip
resistors. If applied regularly the
load is destructive, therefore the
load must not be applied
regularly during the load life of
the resistors. However, the
magnitude of a pulse at which
failure occurs is of little practical
value.
