Applications where high dv/dt is present will operate at high
peak currents (Ip = dv/dt x C). Capacitors should be evaluated in
the actual circuit for dv/dt greater than 2000V/ microsecond. If
repetitive, it may be necessary to use a series resistor or other
impedance to limit peak currents to safe values.
NOTE: Screw torque limit:
12 inch pounds. Use
#8-32, 3/16" long screw to
prevent bottoming.
