Therefore, this is foremost a startup problem. They also used the term "recommended output load capacitance" as opposed to "maximum capacitive load" in the datasheet, which confirms that this is indeed a rather soft maximum spec. Limiting inrush current is an adequate countermeasure.
Why Capacitor Has Leading Power Factor
A pure capacitor loads the power stored is equal to the power return back to the source. Hence A pure capacitor does not store any power.

How much current does a capacitor draw when charging?
The current when charging a capacitor is not based on voltage (like with a resistive load); instead it''s based on the rate of change in voltage over time, or ΔV/Δt (or dV/dt). The formula for finding the current while charging a capacitor is:

How does a decoupling capacitor handle a spike (increase) in the
When your load needs more current, the capacitor will source some extra current. This causes a slight dip in voltage but not a huge one. If there wasn''t a capacitor there, if the load needs a lot of current for a moment, the voltage will droop a lot because the load resistance would have dropped and power supply resistance would consume too much of the voltage.

How to Reduce Motor Load Current with a Capacitor Bank
Supporting wareagle . The capacitor bank is used not to improve the P.F of motor itself; it is used to improve the P.F of the system. Even you add the capacitor bank at the motor terminal; it will reduce the current through the motor cable but not the current (of course the magnitude of the current) drawn by the motor.

What it means is that compared to a resistor where current and voltage are in-phase, when the load is a capacitor then the current peaks (and inverse peaks etc) come earlier than the voltage peaks (and inverse peaks
Capacitive Load definition
Capacitive Load. Apply a DC waveform to a circuit''s terminals, and its only impedance to current flow will be resistance. (DC) so a capacitor appears as an open circuit to a DC current.

6 FAQs about [Is the current of a capacitor a load ]
How does a capacitive load work?
The working principle of capacitive load: the capacitor is connected to the power supply, and the charge is stored on the capacitor plate to form an electric field. When the power supply voltage changes, the capacitor responds, releasing or absorbing charge, changing the waveforms of current and voltage, creating a capacitive load.
What are the different types of capacitor loads?
Types of Capacitive Loads Capacitive loads store electrical energy in a capacitor and release it back into the circuit. Unlike resistive loads or inductive loads, CLs have the characteristic of the current reaching its peak before the voltage does.
What happens when a capacitor is charged?
Once the capacitor is charged in your circuit, no current will flow. If the capacitor is fully discharged, then the current at the start will be 100 V/8 Ω = 12.5 A, but since the power supply can only deliver 5 A you will only get 5 A during the charge phase. As the capacitor charges, the current flow will go to zero.
What is a capacitive load in a power supply?
Capacitive load, the capacitor is connected to the power supply, resulting in a capacitive load, which creates a certain current demand on the power supply. Capacitors store electric charges and play the role of storing and releasing electrical energy in circuits. They are a component that stores electric charges.
Why does a capacitive load have a leading power factor?
In capacitive load, Current leads voltage by 90 degrees. Hence it has a leading power factor. Since the capacitor blocks DC current and allows AC to pass through it, the capacitive load shows very high resistance for DC supply and low resistance for AC.
What is the relationship between voltage and current in a capacitor?
To put this relationship between voltage and current in a capacitor in calculus terms, the current through a capacitor is the derivative of the voltage across the capacitor with respect to time. Or, stated in simpler terms, a capacitor’s current is directly proportional to how quickly the voltage across it is changing.
