Note 1 In-rush current will flow for approximately 1 to 5ms after the power is turned on (at 40°C).
The value of inrush current differs depending on the impedance of the power supply line.
Caution
Inrush current flows for about 5msec after the power comes ON.
The inrush current varies depending on the impedance of the power wiring.
