Kemet ceramic capacitor derating.

How much do you derate tantalum capacitors. We offer the broadest selection of capacitor technologies in the industry along with an expanding range of electromechanical devices emc solutions and supercapacitors. These devices are lead pb free rohs and reach compliant without the need of any exemptions. It can also plot the expected capacitance change with applied voltage.

Kemet s k sim lets you simulate a ceramic capacitor s voltage with applied dc voltage. Class i dielectrics do not exhibit dc bias especially those formulated with calcium zirconate. As an example figure 1 is the derating curve for a kemet t525 ko cap polymer electrolytic capacitor. Derating is expressed usually by percentage of rated voltage that shall be subtracted.

Here we can see the derating advantages kemet s polymer tantalum capacitors have over traditional mno2 tantalum capacitors. Kemet ceramic capacitors are available at mouser electronics. For less than or equal to 10 voltage ratings a 10 derating is recommended. Pme and bme ceramic capacitor devices.

For more information see capacitor marking 2.

The 2 mm pitch option allows for double the packaging quantity of capacitors on a given reel size. Mouser offers inventory pricing datasheets for kemet ceramic capacitors. This option is limited to eia 0603 1608 metric case. Kemet is a leading global manufacturer of electronic components that meet the highest standards for quality delivery and service.

For example 20 derating means that the capacitor shall be used at 80 of rated voltage at the specific applications 10v capacitor to be used on 8v maximum.
