Seven SMD Packages From Vishay Intertechnology Provide MLCC Space-Level Reliability

[SatNews] Vishay Intertechnology, Inc. (NYSE: VSH) has introduced a new series of surface-mount multilayer ceramic chip capacitors (MLCCs) qualified to MIL-PRF-123 for aerospace and military applications.

These high-reliability Vishay Vitramon devices are 100 percent manufactured in Vishay's MIL-STD-790-certified (Cage Code SHV71) facility and are available with BP and BX dielectrics in seven body sizes ranging from 0805 to 2225 and with capacitance as low as 1.0 pF.

To receive MIL-PRF-123 qualification, the MLCCs released  passed 4,000 hours of life testing at 125 degrees Celsius at twice the rated voltage, in addition to 1,000 hours of lot acceptance testing. Manufactured in precious metal technology (PMT/NME) with a wet build process and robust design, the devices provide space-level reliability for avionic, sonar, missile, satellite, and global positioning systems.

MIL-PRF-123 series MLCCs feature maximum voltage to 100 V. Devices with a BP dielectric offer low capacitance down to 1.0 pF, a temperature coefficient of capacitance (TCC) of 0 ppm/°C ± 30 ppm/°C from -55 °C to +125 °C, and an aging rate of 0 % maximum per decade. BX devices provide higher capacitance to 470 nF, TCC of ± 15 % from -55 °C to +125 °C, and an aging rate of 1 % maximum per decade.

The MLCCs feature lead (Pb)-bearing terminations (minimum 4 percent) for tin-whisker-free performance.
