Conducted noise immunity, Power sequencing | Seagate ST3600002FC

6.2.1Conducted noise immunity

Noise is specified as a periodic and random distribution of frequencies covering a band from DC to 10 MHz. Maximum allowed noise values given below are peak-to-peak measurements and apply at the drive power connector.

+5	V	=	250 mV pp from 0 to	100 kHz to 20 MHz.
+12	V	=	800 mV pp from 100	Hz to 8 KHz.
			450 mV pp from 8 KHz to 20 KHz.
			250 mV pp from 20 KHz to 5 MHz.

6.2.2Power sequencing

The drive does not require power sequencing. The drive protects against inadvertent writing during power-up and down.

6.2.3Current profiles

The +12V and +5V current profiles for the ST3600002FC, ST3450802FC and ST3300602FC models are shown below.

Note: All times and currents are typical. See Tables 2 and 3 for maximum current requirements.
