External Capacitance:
For standard units (non C Option) placing large external capacitance on the output may result in operational instability. As a
general rule of thumb, external capacitance should satisfy the equation:
C
exteral
< 0.1millisecond/R
limit
where Rl
imit
is the applicable arc limiting resistance specified in the UM8-40 selection table on page 2 of 6 of the UM8-40
data sheet.
For fast risetime units (C Option) no value of external capacitance will make the unit unstable.
