Вопрос 253

Which of the following is characteristic of an electrolytic capacitor?

  1. Tight tolerance
  2. Much less leakage than any other type
  3. High capacitance for a given volumeПравильный ответ
  4. Inexpensive RF capacitor

Объяснение

An electrolytic capacitor's dielectric is an extremely thin oxide layer formed chemically on the plate, and capacitance rises as the dielectric gets thinner, so a large value fits in a small package. That construction also means loose tolerance and comparatively high leakage, so those choices are wrong.
