PURPOSE: A circuit for inputting power of a monitor is provided to be miniaturized as a sealed case type for building alternating current(AC) power inputting electric elements therein, and to be installed on a printed circuit board(PCB) of a monitor, thereby reducing the size of power inputting circuit of the PCB and diminishing the size of the monitor, then shortening the monitor developing period. CONSTITUTION: The size of a sealed case(20) is maximumly manufactured by multiplying 20mm by 20mm. The sealed case(20) builds a plug inserting terminal, a power switch, a fuse, a line filter, a damping resistor, a capacitor, and other two capacitors. The plug inserting terminal inserts an alternating current(AC) power input plug. The line filter filters a high frequency noise current, and removes the high frequency noise current. The damping resistor eliminates a low frequency ripple current. The two capacitors prevent a leakage current from inversely incoming to the plug inserting terminal.
