Disable Current
• 4mA DC minimum for 1-up ComPAC
• 8mA DC minimum for 2-up ComPAC
DIS–
• 12mA DC minimum for 3-up ComPAC
The MI-ComPAC incorporates an optically isolated master disable input which will shut down the
MI-ComPAC when a current is driven through the disable terminals.

• Thermal impedance, chassis-to-air, is provided for 1-up, 2-up and 3-up MI-ComPAC
package configurations as a function of air flow.
• Case temperature = (total power dissipated x thermal impedance) + ambient temperature.
• Watts dissipated per output = (output power ÷ efficiency) – output power.
(1) To order optional heat sink add –H1 to part number
