High-reliability RoHS-compliant SMD MLCCs for automotive applications

Vishay has introduced a new series of RoHS-compliant, surface-mount multilayer ceramic chip capacitors (MLCCs) for automotive applications. Available with C0G (NP0), X7R, and X8R dielectrics in six body sizes ranging from 0402 to1812, the VJ....31X automotive series devices offer high voltages and high-temperature operation to +150C for increased reliability. The MLCCs released today are manufactured in precious metal technology (PMT/NME) with a wet build process and robust design. Qualified according to AEC-Q200 with PPAP ( available on request) VJ....31X devices are optimized for automotive powertrain, chassis, lighting, and comfort electronics, in addition to industrial sensors. The MLCCs target engine, steering, and headlight control units, battery and power management, and power supplies. The devices with a C0G (NP0) dielectric offer high voltages to 3000VDC, low capacitance down to 1pF, a temperature coefficient of capacitance (TCC) of 0ppm/C ± 30ppm/C from -55C to +125C, and an aging rate of 0 % maximum per decade. Ideal for decoupling and filtering, X7R and X8R devices provide higher capacitance to 1µF, voltages to 1000VDC, TCC of ±15% from -55C to +125C (X7R) and +150C (X8R), and an aging rate of 1% maximum per decade. The MLCCs feature 100% matte tin plate terminations and are available with polymer flexible terminations for additional protection against board flexure damage. The devices are halogen-free and compliant to ROHS and the automotive ELV (End of Life) directive beyond 2016, says the company.
