What is X7R dielectric?
Description. X7R formulations are called “temperature stable” ceramics and fall into EIA Class II materials. X7R is the most popular of these intermediate dielectric constant materials. Its temperature variation of capacitance is within ±15% from -55°C to +125°C. This capacitance change is non-linear.
Are NP0 and C0G the same?
Yes they are equivalent. C0G is the material class that gives an NP0 (NP-zero ) tempco. But it is slang (NP-oh) where the 0 looks like O. Beware that it is often spelt both ways with oh or zero, but it is intended to be a zero in both cases.
What is X5R dielectric?
X5R dielectric is a Class II type dielectric suitable for higher capacitance applications. This dielectric offers high volumetric efficiency. Small case size X5R capacitors are well suited for decoupling and filtering applications in mobile devices, medical devices and other applications with size constraints.
What is the dielectric constant of X7R capacitors?
X7R is commonly used for capacitors with a capacity of 3300pF~0.33uF. Such capacitors are suitable for filtering, coupling, etc., and the dielectric constant is relatively large. When the temperature changes from 0°C to 70°C, the capacitance change is ±15%.
What’s the difference between X5R and y7v capacitor?
X5R and X7R are in Class 2, and Y5V is in Class 3. The first character indicates the lowest temperature that the capacitor can handle. The second character indicates the maximum temperature. The third character indicates the maximum amount of capacitance change over the part’s temperature range.
What is the dielectric constant of Y5V capacitor?
The high dielectric constant of Y5V allows the fabrication of capacitors up to 4.7μF in smaller physical sizes. The value range of the Y5V capacitor is shown in the following table. It is a Class 1 ceramic medium with stable electrical performance and basically does not change with time, temperature and voltage.
Which is a Class 1 dielectric X5R or C0G?
C0G is a Class 1 dielectric, so it’s not included (more on this later). X5R and X7R are in Class 2, and Y5V is in Class 3.
