To obtain the maximum temperature for each of the reference components listed, add 20°C to the 1,000,000
hour MTBF case temperatures. The maximum allowable HDA case temperature is 60°C (see Figure 9). Opera-
tion of the drive at the maximum case temperature is intended for short time periods only. Continuous opera-
tion at the elevated temperatures will reduce product reliability.
