# What is X7R and X5R?

## What is X7R and X5R?

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 theoretical range is from 45°C to 200°C; 5 (as in X5R) corresponds to 85°C, and 7 (as in X7R) corresponds to 125°C.

## 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 difference between C0G and NP0?

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 are MLCC capacitors used for?

Multilayer ceramic capacitors (MLCCs) are generally the capacitor of choice for applications where small-value capacitances are needed. They are used as bypass capacitors, in op-amp circuits, filters, and more.

## What is full form of COG?

COG – Cost of Goods.

## What’s the difference between X7R and X5R capacitors?

Most commonly used capacitor dielectrics are X7R,X8R,X5R,Y5V,Z5U,X7S. 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. Watch this video too :

## What is the theoretical temperature range of a X7R capacitor?

The theoretical range is from 45°C to 200°C; 5 (as in X5R) corresponds to 85°C, and 7 (as in X7R) corresponds to 125°C. The third character indicates the maximum amount of capacitance change over the part’s temperature range.

## 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.
