Deep Dive: G6A08
The correct answer is D: Comparatively low cost. A characteristic of low voltage ceramic capacitors is comparatively low cost. Ceramic capacitors are inexpensive and widely used. For amateur radio operators, this makes them popular for many applications. Understanding this helps when selecting capacitors.
Why Other Answers Are Wrong
Option A: Incorrect. Ceramic capacitors don't have tight tolerance - they typically have ±10-20% tolerance, which is loose. Tight tolerance isn't a characteristic. Option B: Incorrect. Ceramic capacitors don't have high stability - their capacitance varies with temperature and voltage. High stability isn't a characteristic. Option C: Incorrect. Ceramic capacitors don't have high capacitance for given volume - electrolytic capacitors do. Ceramic capacitors are relatively small capacitance.
Exam Tip
Low voltage ceramic capacitor characteristic = comparatively low cost. Think 'C'eramic 'C'apacitor = 'C'heap 'C'apacitor. Ceramic capacitors are inexpensive and widely used. Not tight tolerance, not high stability, not high capacitance - just low cost.
Memory Aid
Low voltage ceramic capacitor characteristic = comparatively low cost. Think 'C'eramic 'C'apacitor = 'C'heap 'C'apacitor. Ceramic capacitors are inexpensive and widely used. Popular for many applications.
Real-World Example
You need capacitors for bypass and coupling in your RF circuits. Low voltage ceramic capacitors are inexpensive (e.g., $0.10 each) and work well for these applications. Their low cost makes them popular for many circuit applications, even though they don't have tight tolerance or high stability.
