Calculate the capacitance values at extreme temperatures for a 100 nF capacitor if the ceramic material classes are Y5E

For a ceramic capacitor classified as **Y5E**, the temperature characteristics are as follows:

- The first letter, **Y**, indicates the lower temperature limit of **-30°C**.
- The second digit, **5**, represents the upper temperature limit of **85°C**.
- The third letter, **E**, signifies a capacitance tolerance of **±4.7%** over the specified temperature range.

Given that the nominal capacitance is **100 nF**, we can calculate the capacitance at the extreme temperatures by considering the worst-case tolerance of ±4.7%.

1. **At -30°C:**
   - Minimum capacitance: \( 100 \text{ nF} - 4.7\% = 100 \text{ nF} \times (1 - 0.047) = 95.3 \text{ nF} \)
   - Maximum capacitance: \( 100 \text{ nF} + 4.7\% = 100 \text{ nF} \times (1 + 0.047) = 104.7 \text{ nF} \)

2. **At 85°C:**
   - Minimum capacitance: \( 100 \text{ nF} - 4.7\% = 95.3 \text{ nF} \)
   - Maximum capacitance: \( 100 \text{ nF} + 4.7\% = 104.7 \text{ nF} \)

Thus, the capacitance values at extreme temperatures for this **100 nF Y5E** ceramic capacitor range from **95.3 nF to 104.7 nF**.
