Table 2: PCBA and HDA temperatures

Notes.

[1]

Section 8.3.1 describes the air-flow patterns used when generating the 1,200,000 hours MTBF guide-
lines in column 2. Air flow was opposite that shown in Section 8.3.1. Local air velocity was 0.914 m/sec
(180 lfpm). Inlet air temperature to the drive was 77°F (25°C), plus 9°F (5°C) temperature rise in the

test enclosure (86°F/30°C ambient local to the drive).

–40° to 158°F (–40° to 70°C) package ambient with a maximum gradient of 36°F (20°C) per hour. This
specification assumes that the drive is packaged in the shipping container designed by Seagate for use with
drive.
