form factor




  • For a periodic quantity such as AC, the ratio of the RMS value to the half-period average value. The form factor for a pure sine wave is approximately 1.111.
  • A function which takes into account the ratio of the diameter to length of a coil when computing its inductance. Also called shape factor (3).
  • In computers, the size and shape of a given component, such as a circuit board or disk drive.
