*Question G6A08:
Which of the following is characteristic of low voltage ceramic capacitors?*  

*Correct Answer is  D: Comparatively low cost*  

### AI Response: (may contain errors)  

Low voltage ceramic capacitors are commonly used in various electronic applications, and understanding their characteristics is important for the Extra Class exam.

### Correct Answer: D - Comparatively low cost

- **Explanation**: Low voltage ceramic capacitors are generally less expensive to manufacture compared to other types of capacitors, such as electrolytic or tantalum capacitors. This cost-effectiveness makes them a popular choice for many applications.

### Why the Other Choices are Incorrect:

- **A: Tight tolerance**  
  - **Explanation**: While some ceramic capacitors can have tight tolerances, many low voltage ceramic capacitors have a wider tolerance range compared to other types, such as film capacitors. Therefore, this statement is not universally true for all low voltage ceramics.

- **B: High stability**  
  - **Explanation**: Ceramic capacitors can exhibit changes in capacitance with temperature and voltage (known as voltage coefficient), especially in Class 2 dielectrics (like X7R or Y5V). This makes them less stable than other capacitor types, such as film capacitors, which are known for their stability.

- **C: High capacitance for given volume**  
  - **Explanation**: While ceramic capacitors can provide good capacitance values, they do not necessarily offer the highest capacitance for a given volume compared to other types, such as electrolytic capacitors, which can achieve much higher capacitance values in similar sizes.

### Summary

- Low voltage ceramic capacitors are characterized by their comparatively low cost, making them a popular choice in many electronic circuits. Understanding the limitations and characteristics of these capacitors helps in selecting the right component for specific applications.
