Power ceramic capacitors can be supplied with high rated voltages in the range of 2 kv up to 100 kv.
Ceramic capacitor power rating.
Either the maximum voltage rating or the maximum power dissipation of the part limits the maximum current through a capacitor.
Historically the dv dt rating of multi layer ceramic capacitors mlcc s is not a parameter that has generally been requested by customers or provided by manufacturers.
For this reason some special styles.
Power ceramic capacitors can be made to withstand voltages in the range of 2kv up to 100 kv with a power specified at much higher than 200 volt amperes.
Smaller mlccs used in printed circuit boards are rated to voltages from only a few volts up to several hundreds of volts depending on the application.
Dv dt ratings for multi layer ceramic capacitors.
Applicable to temperature characteristics u2j 7u c0g 5c beyond rated voltage of 200vdc since the self heating is low in the low loss series the allowable power becomes extremely high ompared to the common x7r r7 characteristics however when a load with self heating of 20 c is applied at the rated voltage the allowable power may be exceeded.
The dimensions of these power ceramic capacitors can be very large.
In contrast you can find a 0 1 µf x7r cap in the 0306 package and with a voltage rating 10 v high enough for 3 3 v or even 5 v circuitry.
This note discusses the relationship of current handling power dissipation applied voltage and the maximum rated voltage of a multi layer ceramic capacitor.
Class 2 power ceramic capacitors are used for circuit breakers for power distribution lines for high voltage power supplies in laser applications for induction furnaces and in voltage doubling circuits.
