Vishay Intertechnology’s surface-mount X7R multilayer ceramic chip capacitors (MLCCs), the VJ1206, VJ1210, VJ1808, and VJ1812 HVArc Guard series, is designed to prevent surface arc-over at high voltages. This design allows for higher capacitances than standard high-voltage MLCCs, and facilitates the use of smaller case sizes in high-voltage products.
Capacitances for the MLCCs range from 100 pF to 0.27 µF, and offer twice the standard voltage breakdown, with voltage ratings from 250 Vdc to 1000 Vdc. The devices eliminate the need for conformal coating, and can replace wire-leaded through-hole capacitors. Samples and production quantities are available now. Pricing starts at $0.14.
