Electronics Tutorial about connecting Capacitors in Parallel and how to calculate the total Capacitance of Parallel Connected Capacitors
$begingroup$ One reason for a resistor to be present here would be to ensure the discharge of the X2 capacitor per IEC-950 recommendations: the voltage across the power plug prongs should drop quickly after unplugging the cord from the ac outlet. But a) these resistors are not mandatory for a X2 cap. of 100 nF or less and b) the value is quite high to avoid any …

There are two capacitors in parallel between pins 6 and 7 (GND and V DD.) One is 4.7 uF and the another is 0.1 uF, so the parallel result is 4.8 uF. Why is the 0.1 uF capacitor needed? It doesn''t seem to be a precision-critical component, because it''s just in parallel to the power supply (I think just to stabilize the voltage).
