Fujitsu MCP3130SS, MCP3064SS, MCM3064SS, MCM3130SS manual AC noise filter recommended

Installation Requirements

(4) Power supply to SCSI terminating resistor

If the power for the terminating resistor is supplied from the drive to other SCSI devices through the SCSI bus, the current-carrying capacity of the +5 VDC power supply line to the optical disk drive must be designed with consideration of an increase of up to 900 mA.

Select a method of power supply to the drive in accordance with the setting terminal of the optical disk drive. See Subsection 4.3.3.

(5) Noise filter

To eliminate AC line noise, a noise filter should be installed at the AC input terminal on the power supply unit of the drive. The noise filter specifications are as follows:

￿Attenuation: 40 dB or more at 10 MHz

￿Circuit configuration: The T-configuration shown in Figure 3.12.
