Both leads to heat sink, with lengths as shown. Variations in R
JL(t)
below 2.0 seconds are independent of lead connections of 1/8 inch
or greater, and vary only about ±20% from the values shown. Val-
ues for times greater than 2.0 seconds may be obtained by drawing
a curve, with the end point (at 70 seconds) taken from Figure 8, or
calculated from the notes, using the given curves as a guide. Either
typical or maximum values may be used. For R
JL(t)
values at pulse
widths less than 0.1 second, the above curve can be extrapolated
down to 10 s at a continuing slope.
