6 Frequently Asked Questions about “Capacitor withstand voltage devices”
What happens if a capacitor exceeds rated voltage?
Capacitors have a maximum voltage, called the working voltage or rated voltage, which specifies the maximum potential difference that can be applied safely across the terminals. Exceeding the rated voltage causes the dielectric material between the capacitor plates to break down, resulting in permanent damage to the capacitor.
Do film capacitors have a good balance?
Generally speaking, the capacitance and withstand voltage (rated voltage) of capacitors are in a trade-off relationship which is difficult to balance. In MLCC of the same size, when increasing the withstand voltage, the capacitance tends to decrease. Film capacitors possess a good balance of high withstand voltage and capacitance.
What are the standards for a capacitor?
These standards vary depending on the application of the capacitor, but some common standards include: • IEC 60950: Sets guidelines for insulation testing in information technology equipment. • UL 60950: Provides standards for leakage current and dielectric strength in electrical components.
What is a high power resonance capacitor?
High-power resonance capacitors are an important component in magnetic resonance using wireless power transfer EV charging systems. This is because a high-accuracy resonance circuit with high withstand voltage is required for quick, efficient wireless transfer of a large amount of power.
What determines the rated voltage of a capacitor?
The rated voltage depends on the material and thickness of the dielectric, the spacing between the plates, and design factors like insulation margins. Manufacturers determine the voltage rating through accelerated aging tests to ensure the capacitor will operate reliably below specified voltages and temperatures.
Why do we use film capacitors?
However, since larger voltage rectangular waves than those in general electronic devices are applied, high withstand voltage (rated voltage) is required. Since a large current flows in resonance circuits, superior ESR is required. In the past, film capacitors were normally used as resonance capacitors in the LLC converters of onboard chargers.
