Coated disk capacitors or conformal coated leaded through-hole capacitors are commonly used in voltage multiplier sections, but they take up a large amount of board space. HVArc Guard® surface-mount capacitors offer designers a space saving alternative along with reducing manufacturing cost by eliminating the manual insertion processes associated with through-hole devices. Vishay Vitramon's HVArc Guard® surface-mount capacitors patented internal construction technology eliminates the need to conformal coat the part or over-coat the circuit board to prevent surface arc-over.
