← ScienceWhich outcome occurs when a poorly manufactured high-frequency capacitor exceeds its voltage rating in an RF amplifier?
A)Dielectric breakdown and arc formation✓
B)Increased equivalent series resistance (ESR)
C)Decreased self-resonant frequency (SRF)
D)Higher amplifier gain at all frequencies
💡 Explanation
Dielectric breakdown results in arc formation because the high voltage exceeds the dielectric's strength, overcoming its insulating properties, leading to a conductive path rather than maintaining charge separation. Therefore, arcing happens; rather than ESR increases or frequency decreases, both of which are related to smaller overloads
