Input noise ripple is measured at the host system power supply across an equivalent 80-ohm resistive load on 
the +12 V line or an equivalent 15-ohm resistive load on the +5V line.

• Using 12V power, the drive is expected to operate with a maximum of 120mV peak-to-peak square-wave 

injected noise at up to 10MHz.

• Using 5V power, the drive is expected to operate with a maximum of

100mV peak-to-peak square-wave 

injected noise at up to 10MHz.

Note. Equivalent resistance is calculated by dividing the nominal voltage by the typical RMS read/write 

current.

Voltage tolerance (including noise):
