Calculate the capacitance values at extreme temperatures for a 100 nF capacitor if the ceramic material classes are Y5y

The capacitance of a ceramic capacitor varies with temperature based on the material class it belongs to. In this case, you have a 100 nF capacitor with a ceramic material class of **Y5Y**. This class follows specific temperature coefficients that describe how capacitance changes with temperature.

### Breakdown of the Y5Y Class:

- **Y**: The temperature range is from **−30°C to +85°C**.
- **5**: The reference temperature is **25°C**.
- **Y**: The capacitance can vary by **±22%** over the full temperature range.

Now, let's calculate the capacitance at the extreme temperatures:
- **At -30°C**: The capacitance can decrease by up to 22%.
- **At +85°C**: The capacitance can increase by up to 22%.

### Calculating Capacitance at -30°C:

\[
C_{\text{-30°C}} = 100 \, \text{nF} \times (1 - 0.22) = 100 \, \text{nF} \times 0.78 = 78 \, \text{nF}
\]

### Calculating Capacitance at +85°C:

\[
C_{\text{+85°C}} = 100 \, \text{nF} \times (1 + 0.22) = 100 \, \text{nF} \times 1.22 = 122 \, \text{nF}
\]

### Final Results:
- **At -30°C**: 78 nF
- **At +85°C**: 122 nF

So, the capacitance of your 100 nF capacitor with Y5Y ceramic material will vary between **78 nF** and **122 nF** across the temperature range of **−30°C to +85°C**.
