← ScienceWhich risk increases when stray capacitance forms between traces on a high-frequency PCB?
A)Signal distortion from parasitic inductance
B)Reduced gate drive strength on fast switching
C)Electromagnetic interference emission levels✓
D)Overheating resulting from increased resistance
💡 Explanation
When stray capacitance exists, parasitic capacitive coupling occurs between traces because the PCB acts as a unintended capacitor, increasing electromagnetic interference (EMI) emissions. Therefore increased EMI results, rather than distortion, reduced drive, or overheating which involve different effects and components.
