Vishay Intertechnology Inc. has rolled a multilayer ceramic chip capacitor (MLCC) that touts an integrated resistor. The VJ controlled discharge capacitor (CDC) features a low electrostrictive ceramic formulation for repeated charge and discharge cycles, allowing the device to achieve very high field reliability, the company stated.

For high-pulse-current applications, the VJ CDC offers high voltage ratings from 1-1.5kVDC and capacitance range from 33-560nF. The capacitor is manufactured in noble metal electrode (NME) technology with a wet build process.

The integration of a high-capacitance MLCC with a bleed resistor on its surface allows the VJ CDC to discharge more rapidly while also reducing board space requirements and assembly costs. Typical applications for the device include detonation devices (munitions, pyrotechnics, blasting) and electronic fuzing.

The VJ CDC is offered in three case sizes, and is available with X7R and X5P dielectrics. The device features a wide capacitance range of 33-220nF in the 3040 case size, 47-330nF in the 3640, and 100-560nF in the 4044.

The capacitor offers a temperature coefficient of capacitance (TCC) of 10 percent from -55C to 85C with the X5P and 15 percent from -55C to 125C for the X7R. The device is halogen-free according to the IEC 61249-2-21 definition.

Production quantities of the VJ CDC are available with lead times starting from 14 weeks.
