在一些电压较高的感应充电器使用中，需求选用高压安稳的电容作为谐振电容。由于感应充电器的初级线圈需求选用交流电压驱动，因而有必要对电容进行相应的调整。

感应充电器需求具有高击穿电压(VBD)功能，一起，某些使用中还需求防护高压电弧放电。为避免电弧放电，电路板一般敷有维护涂层，或者经过合理安排元器材布局到达高压侧与电路板其他部分阻隔的效果，等。但这种方法往往需求很大的电路板空间，由于高压电路一般选用体积较大的引线型通孔插装电容。

为处理这一问题，Vishay推出了一系列的HVArc(高压电弧)防护MLCC(多层贴片陶瓷电容)，可防止电弧放电，一起节约空间。这些新器材在较高的电压定额内具有大容量，而且进步了电压击穿的耐受才能。

高压电弧放电会造成断路，并有可能损坏其他元器材。标准的高压SMD电容终究将会失效短路，这取决于电弧放电的次数和存在问题的部分。VishayHVArc防护电容能够吸收所有的能量，因而，此电容能够在高压下进行正常作业，至少在到达高压击穿极限之前，不会发生破坏性电弧放电。

In the use of some induction chargers with high voltage, it is necessary to choose a high-voltage stable capacitor as a resonant capacitor. Since the primary coil of the induction charger needs to be driven by AC voltage, it is necessary to adjust the capacitance accordingly.

Induction chargers require a high breakdown voltage (VBD) function and, in some uses, protection against high-voltage arc discharge. In order to avoid arc discharge, the circuit board is generally coated with a maintenance coating, or the effect of blocking the high voltage side from the other parts of the circuit board through a reasonable arrangement of the device layout. However, this method often requires a lot of circuit board space, because the high-voltage circuit generally uses a larger lead through hole cartridge capacitor.

To address this issue, Vishay has introduced a range of HVArc(High voltage arc) protected MLCCS (Multilayer chip ceramic capacitors) that prevent arc discharge and save space together. These new devices have a large capacity at a higher voltage rating and improve the ability to withstand voltage breakdown.

High voltage arc discharge can cause circuit breaks and may damage other components. Standard high-voltage SMD capacitors will eventually fail and short-circuit, depending on the number of arcs discharged and the part in question. The VishayHVArc protective capacitor absorbs all the energy, so it can operate normally at high voltages without damaging arcs, at least until the high voltage breakdown limit is reached.
