Rugged automotive-qualified capacitors

June 14, 2013 // By Graham Prophet
Vishay Intertechnology has added to its VJ Automotive Series of SMD MLCCs that save board space and increase reliability. With X8R dielectric, high-temperature devices now offer 0402 case size, and higher 100V ratings for 0603 and 0805 case sizes

The VJ automotive series of surface-mount multilayer ceramic chip capacitors (MLCCs) is designed for high-temperature automotive applications. To save board space, the VJ….31 / VJ….34 now offer a 0402 case size with an X8R dielectric. In addition, the 0603 and 0805 case sizes featuring an X8R dielectric have been enhanced, now offering working voltages of 100 V.

The new VJ automotive series devices are available in terminations with 100 % tin plate matte finish (VJ….31), and for hybrid applications the devices are available with a conductive epoxy assembly termination (VJ….34).

These capacitors are manufactured in Noble Metal Electrode Technology (NME) with a wet build process, and they are qualified according to AEC-Q200 with PPAP available on request. Typical applications for the devices will include sensors, engine/ignition control, power steering and active safety controls, and controls for doors, windows, and air conditioning.

The new VJ automotive series devices offer voltage ratings up to 100 V and a wide capacitance range of 330 pF to 27 nF. The VJ….31 / VJ….34 X8R MLCCs provide a temperature coefficient of capacitance (TCC) of ± 15 % over the temperature range of -55 °C to +150 °C.
