High Voltage
Ceramic Capacitor
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.
