When manufacturer says that this is a x7r capacitor it means that the capacitor can operate from 55 degrees centigrade to 125 degrees centigrade temperature and the capacitance of the capacitor will not vary more or less than 15 from its nominal value specified.

X7r capacitor tolerance. Its temperature variation of capacitance is within 15 from 550c to 1250c. The first character indicates the lowest temperature that the capacitor can handle. X7r is the most popular of these intermediate dielectric constant materials.

Modern c0g np0 formulations contain neodymium samarium and other rare earth oxides. They work from 30oc to 85oc and the tolerance is 22 82.

Capacitance change is limited to 15 from 550c to 1250c. X7r is the most popular of these intermediate dielectric constant materials. C0g np0 ceramics offer one of the most stable capacitor dielectrics available.

C0g is a class 1 dielectric so its not included more on this later. This capacitance change is non linear. The choice of capacitance is determined by the circuit configuration but the value read on the side of a capacitor may not necessarily be its actual value.

The characteristics are similar to the previous ones but the maximum temperature. The typical aging of x7r ceramic capacitors is about 25 per decade the aging rate of z5u ceramic capacitors is significantly higher and can be up to 7 per decade. Capacitance for x7r varies under the influence of electrical operating con ditions such as voltage and frequency.

X7r formulations are called temperature stable ceramics and fall into eia class ii materials. X7r capacitance voltage availability capacitance values pf uf cap. The aging process of class 2 capacitors may be reversed by heating the component above the curie point.

The second character indicates the maximum temperature. Its temperature variation of capacitance is within 15 from 550c to 1250c. The letter x as in x7r x5r corresponds to 550c.

This capacitance change is non linear. X7r exhibits a predictable change in capacitance with respect to time and voltage boasting a minimal change in capacitance with reference to ambient temperature. X5r and x7r are in class 2 and y5v is in class 3.

All capacitors have a tolerance rating that can range from 20 to as high as 80 for aluminium electrolytics affecting its actual or real value. 10 10 a 0 i 100 0001 101 120 00012 121 150 00015 151. C0g np0 is the most popular formulation of the temperature compensating eia class i ceramic materials.
