MIL-PRF-123-qualified MLCCs offer extreme reliability
Vishay Intertechnology has introduced a 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 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 1.0pF.
To receive MIL-PRF-123 qualification, the MLCCs have passed 4,000 hours of life testing at 125°C 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 avionics, sonar, missile, satellite, and global positioning systems.
The MIL-PRF-123 series MLCCs feature maximum voltage to 100V. Devices with a BP dielectric offer low capacitance down to 1.0pF, a Temperature Coefficient of Capacitance (TCC) of 0ppm/°C ±30ppm/°C from -55 to +125°C, and an aging rate of 0% maximum per decade. BX devices provide higher capacitance to 470nF, TCC of ±15% from -55 to +125°C, and an aging rate of 1 % maximum per decade. The MLCCs feature lead (Pb)-bearing terminations (minimum 4%) for tin-whisker-free performance.
