Typical current profile

2.9.2
Conducted noise
Input noise ripple is measured at the host system power supply across an equivalent 15-ohm resistive load on
the +5 volt line.
Using 5-volt power, the drive is expected to operate with a maximum of 100 mV peak-to-peak square-wave
injected noise at up to 10 MHz.
Note.
Equivalent resistance is calculated by dividing the nominal voltage by the typical RMS read/write
current.
