2.8.1.1 Typical current profiles

2.8.2 Conducted noise
Input noise ripple is measured at the host system power
supply across an equivalent 80-ohm resistive load on
the +12 volt line or an equivalent 15-ohm resistive load on the +5 volt line.
• Using 12-volt power, the drive is exp
ected to operate with a maximum of 120 mV peak-to-peak square-wave
injected noise at up to 10 MHz.
• Using 5-volt power, the drive is expected to operate with a maximum of 10
0 mV peak-to-peak square-wave
injected noise at up to 10 MHz.
Note. Equ
ivalent resistance is calculated by dividing the nominal voltage by the typical RMS read/write
current.
2.8.3 Voltage tolerance
Voltage tolerance (including noise):
5V
± 5%
12V ± 10%
