Table 14: Magnetic flux density limits Frequency (KHz) Limits (uT RMS) 61-100 250 101-200 100 201-400 50 6.1.3 Conductive noise The disk drive shall work without soft error degradation in the frequency range from DC to 20 Mhz injected through any two of the mounting screw holes of the drive when an AC current of up to 45 mA (p-p) is applied through a 50-ohm resistor connected to any two mounting screw holes. 6.1.4 Magnetic fields The disk drive will withstand radiation and conductive noise within the limits shown below. The test method is defined in the Noise Susceptibility Test Method specification, P/N 95F3944. 6.2 DC power requirements Connection to the product should be made in a safety extra low voltage (SELV) circuits. The voltage specifications are applied at the power connector of the drive.
