The main differences between safety regulated capacitors and ordinary capacitors are as follows:

Failure mode: Ordinary capacitors will exhibit a short circuit state after failure, while safety capacitors will exhibit an open circuit state.

This means that when ordinary capacitors fail, the circuit may experience faults or short circuits; In contrast, the design of safety capacitors allows them to be non-conductive in the event of failure.

Voltage withstand level: Safety capacitors can usually withstand higher voltages, some even reaching a nominal voltage of 2kV or above, while the actual voltage withstand of ordinary capacitors is about 500V. This makes safety capacitors more suitable for application in high voltage scenarios.

Safety: Due to its design differences, safety capacitors can provide higher safety. After the external power supply is disconnected, ordinary capacitors may have residual charges, which may cause electric shock if touched by someone at this time. However, safety capacitors do not retain charges, thus eliminating this potential safety risk.

Application scope: Safety capacitors are mainly used in situations that require high safety, such as medical equipment and safety power supplies, while ordinary capacitors are widely used in signal shaping, filtering, and energy storage of general electronic products.

Materials and manufacturing processes: Safety capacitors are usually produced using higher quality and stricter management standards, which are also reflected in their prices.

Discharge characteristics: Ordinary capacitors may retain charge after power disconnection, while safety capacitors quickly discharge after power disconnection, reducing this risk.

In summary, the main difference between safety capacitors and ordinary capacitors lies in their failure behavior, voltage resistance, safety, and handling of charges after power disconnection. These characteristics determine their applicability in different application scenarios.
