Both leads to heat sink, with lengths as shown. Variations in RqJL(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. Values

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 RqJL(t) values at pulse

widths less than 0.1 second, the above curve can be extrapolated

down to 10

µs at a continuing slope.
