The capacitor is for EMI filtering, it is there to reduce common mode noise. Yes they are ground terminals. One is the ground reference for unisolated mains input side, the other one is the ground reference for isolated low voltage output side. Therefore it must be of special type for safety reasons, the type is called an Y capacitor.
When a capacitor is being charged, negative charge is removed from one side of the capacitor and placed onto the other, leaving one side with a negative charge (-q) and the other side with a positive charge (+q). The net charge of the capacitor as a whole remains equal to zero.
A solution is to create a circuit board that establishes a ground with the characteristics of node_G. The principle is simple—the circuit trace from the input ground terminal to the ground side of R1 should be a clear path with no connections to contaminating sources of current along the way (figure 2).
There are two important reasons why every integrated circuit (IC) must have a capacitor connecting every power terminal to ground right at the device: to protect it from noise which may affect its performance, and to prevent it from transmitting noise which may affect the performance of other circuits.
EMI can be particularly disruptive in communication systems, leading to data loss or corrupted signals. Y capacitors are used in the filters of these systems to ensure clear communication by grounding the noise. The stakes for EMI mitigation are even higher in medical equipment, where device malfunction could endanger lives.

Y capacitors provide a low-impedance path to ground, filtering out high-frequency noise. They are crucial for meeting regulatory standards for EMI emissions. Their unique design ensures safety through fail-open mechanisms rather than fail-short, preventing catastrophic failures.
The capacitors to ground form a low-pass filter for the lines they''re connected to, as they remove high-frequency signals from the line by giving those signals a low-impedance path to GND. See this question.
To suppress the high frequency common mode is is necessary to put capacitors between the input and output side of the power supply with a capacitance substantially higher than the capacitance in the flyback transformer. This effectively shorts out the high frequency and prevents it escaping from the device. Source:
Capacitors between power and ground is used to suppress spikes. These spikes can damage the board, or at least, the sensitive components. The larger the value of the …
Thank you highlighting another aspect of good grounding. Beside all abstract views additonal two topics impact grounding of bypass capacitors: thermals and vias. - Thermals on capacitor''s grounding pad act like a resistor and inductor. They are needed to ensure good soldering. Routing wires close by may reduce the number of thermals easily from ...
Chassis grounding not only helps in protecting the PCB from surges and ground noise, but it may also act as a shield against EMI. A grounded, enclosed chassis can be an effective Faraday cage, which protects the PCB from external interference. Applying Chassis Grounding Techniques. Chassis grounding can be tricky. If not done properly, you''ll ...
Electronics: Why a capacitor is connected between two ground terminals and what difference does it make?Helpful? Please support me on Patreon: https://
Grounding a capacitor involves connecting one of its terminals to the ground or earth. This is typically done using a wire. The ground serves as a reference point and helps to stabilize the voltage across the capacitor. It also provides a path for the discharge of the stored energy in the capacitor, which can be important for safety reasons.
On development boards, there are usually many 0.1uF non-electrolytic capacitors and 10uF electrolytic capacitors between the DC power supply and ground. The purpose of these capacitors is to make the power and …
The previous three sections of Lesson 2 discussed the three common methods of charging - charging by friction, charging by induction, and charging by conduction.A discussion of charging would not be complete without a discussion of uncharging.Objects with an excess of charge - either positive or negative - can have this charge removed by a process known as grounding.

Where there are a few inches of wire tying the individual grounds together, it is a good idea to insert fast signal diodes and a capacitor as shown between the separate ground runs. Any potential difference developed between the …
If the capacitors must be arranged in a group of four, for example, the one on the edge closest to the power transformer should be used for the first star point, and the one farthest from this edge should be used for the first stage preamp star ground, with the other star grounds in between. The ground lugs for the capacitors can then be connected to the chassis in such a manner as to …
The capacitor is used to short RF to ground in the event of EMI. Additionally, in this configuration the resistor is specifically called a "bleeder resistor." A bleeder resistor …
Where there are a few inches of wire tying the individual grounds together, it is a good idea to insert fast signal diodes and a capacitor as shown between the separate ground runs. Any potential difference developed between the separate grounds due to finite impedance of wiring, as shown in Figure 1, will be attenuated and clamped by the three ...
Why are capacitors grounded? The capacitors to ground form a low-pass filter for the lines they''re connected to, as they remove high-frequency signals from the line by giving those signals a low-impedance path to GND.
decent grounding performance if the power bus has a very low impedance. This is recommended ONLY if implementing the star grounding technique is not possible. Device 1 and Device 2 are connected together and then go to a common connection to Device 5. Device 3 and Device 4 are connected together as well and go to the same common connection to Device 5. DEVICE 1 …

- Thermals on capacitor''s grounding pad act like a resistor and inductor. They are needed to ensure good soldering. Routing wires close by may reduce the number of thermals easily from 4 to 3 to 2 to 1 and result in increase resistance and inductance the other way.
On development boards, there are usually many 0.1uF non-electrolytic capacitors and 10uF electrolytic capacitors between the DC power supply and ground. The purpose of these capacitors is to make the power and ground lines low impedance and the power supply close to an ideal voltage source.

This is because the current into one terminal of a capacitor must equal the current out of the other terminal thus, no net electric charge accumulates in the capacitor. Instead, one can think of electric charge being ''pumped'' from one plate of the capacitor to the other.
The concepts of grounding techniques, earthing, making PCB ground connections, and PCB chassis ground are all very convoluted in electronics, despite international standards that have tried to separate concepts and terminology. Grounding is important in every aspect of electronics design, electrical work, and of course, in PCB design.
