(1) External resistor divider variation is not considered.
(2) Design information — not tested, ensured by characterization.
(3) This information only will NOT be tested in production. The equation is based on:
(C × 1) / (9.5 × 10–6) = tDelay (delay time)
Where
tab● C = delay capacitor value capacitance
tab● C range = 100 pf to 500 nF
