Hi Stefan,
Usually, this is the discharge time into essentially a dead short, not the time of one oscillation. One cycle consists of charge-discharge-reverse charge-discharge. Therefore, the the minimum time for one cycle would be not less than four times this, limiting the oscillating frequency to something less than ~55.5 kHz. Trying to operate above this frequency will result in high heat dissipation and very fast damping of voltage. The internal resistance may even be high enough to prevent oscillation altogrther.

Probably discharge time. It can take 300 discharges per second, and each
discharge elapses in 4.5 microseconds.
