Difference between X7R, X5R, X8R, Z5U,Y5V, X7S, C0G Capacitor dielectricsDifference between X7R, X5R, X8R, Z5U,Y5V, X7S, C0G Capacitor dielectrics - Embedded World
Ceramic capacitors are broadly categorized into 4 classes based on the dielectrics used in them,
Class 3and Class 4capacitors are not widely used and hence have not been standardized.
Class 1 capacitors have following characteristics,
- Their capacitance varies linearly with temperature
- Their capacitance does notdepend on the applied voltage
- They do not suffer significant aging process due to para electric materials used in manufacturing
- Have significantly low electrical losses compared to Class 2capacitors
- Due to the above properties they are used in applications likeresonant circuits, PLL and Oscillators.
They use a 3 digit notation to indicate the dielectric used in them according to EIA RS-198 standard
Look at the below table, (Source : Wikipedia)
Class 2 capacitors are specifications mentioned above are for operation within fixed temperature range of +25 degrees centigrade to +85 degrees centigrade.
Class 2 capacitors have following characteristics
- Their capacitance varies non linearly with temperature
- Their capacitance highly depends on the applied voltage
- They suffer significant aging process due to ferro electric materials used in manufacturing
- Have significantly high electrical losses compared to Class 1 capacitors
- Due to high Permittivity they have high volumetric efficiency
- Due to high Permittivity large capacitance values can be achieved in small device casings like 0201, 0402, 0603
- Due to the above properties they are used in applications like bypassing, coupling, decoupling.
They use a 3 digit notation to indicate the dielectric used in them according to EIA RS-198 standard
Refer the table below, (Source : Wikipedia)
So according to the above table,
When manufacturer says that this is a capacitor, it means that the capacitor can operate from – degrees centigrade to +degrees centigrade temperature and the capacitance of the capacitor will not vary more or less than from its nominal value specified.
Similarly, When manufacturer says that this is a capacitor, it means that the capacitor can operate from -30 degrees centigrade to +85 degrees centigrade temperature and the capacitance of the capacitor will not increase more than and not decrease below from its nominal value.
Most commonly used capacitor dielectrics are .
Although Class 1 capacitors have more advantages than Class 2 capacitors, I encounter more X7R and X5R capacitors on day to day basis than C0G capacitors.
