Ceramic Capacitor Voltage Range

Ceramic disc capacitors have a capacitance value of about10pf to 100μf with a wide variety of voltage ratings between 16v to 15 kv and more.

Ceramic capacitor voltage range.

Equivalent series resistance esr like any other physical material the terminals on a capacitor have a very tiny amount of resistance. 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. In our company withstanding voltage test is performed at 2 5 to 3 times rated voltage 100 or 1 2 to 2 5 times rated voltage 100 of rated voltage. To gain higher capacitances these devices can be made from multiple layers.

5 as in x5r corresponds to 85 c and 7 as in x7r corresponds to 125 c. However it causes the reduction of reliabilities to use over the rated voltage. The spec for r capacitors such as x5r and x7r is 15. The theoretical range is from 45 c to 200 c.

In case that the applied voltage exceeds the rated voltage and does not exceed the voltage mentioned above ceramic capacitors are not broken instantly. A capacitor may have a 50 volt rating but it will not charge up to 50 volts unless it is fed 50 volts from a dc power source. Power ceramic capacitors can be supplied with high rated voltages in the range of 2 kv up to 100 kv. 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.

The mlccs are made with paraelectric and ferroelectric materials mix and alternatively layered with metal contacts. Voltage range from 16v 25v 50v 63v 100v 500v 1kv 2kv and max reach 50kv for high voltage ceramic cap. Otherwise it will explode. Semec ceramic capacitors are available with high voltage type low voltage ceramic disc type radial multilayer and chip mlcc.

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. The voltage rating is only the maximum voltage that a capacitor should be exposed to not the voltage that the capacitor will charge up to. Different material npo x7r y5v make ceramic capacitor used in different application which are suitable for low lost circuits timing and tuning applications etc. Maximum voltage every capacitor has a maximum voltage that it can handle.

You ll find max voltages anywhere from 1 5v to 100v. This can become a problem if you need to be mindful of heat and power loss.
