Surface-mount X7R MLCCs Rated at 100pF to 0.27µF

(Product News, 22 Sep 2008)

Vishay Intertechnology Inc. has released its HVArc Guard surface-mount X7R multilayer ceramic chip capacitors (MLCCs) that are available with optional polymer terminations especially constructed to withstand higher levels of mechanical stress. With optional polymer terminations, the VJ0805, VJ1206, VJ1210, VJ1808, and VJ1812 HVArc Guard MLCCs reduce capacitor failures and save warranty costs by confining failures to the capacitor, thus reducing the number of damaged components on the circuit board or damage to the complete device itself.

Optimized for applications including buck and boost dc-to-dc converters, voltage multipliers for flyback converters, and lighting ballast circuits, the MLCCs will be used in lighting systems and power supplies for medical, computer, motor control, construction and mining, and telecommunications applications.

The VJ HVArc Guard devices feature a patented internal design structure that prevents surface arc-over at high voltages—allowing for higher capacitances than standard high-voltage MLCCs, and facilitates the use of smaller case sizes in high-voltage products, allowing for device miniaturization and reducing component cost.

The capacitors feature capacitances ranging from 100pF to 0.27µF, and offer twice the voltage breakdown in air of standard products with voltage ratings from 250V DC to 1kV DC. The devices eliminate the need for conformal coating, and can replace wire leaded through-hole capacitors.
