MIL-PRF-123 Space Qualified, Multi-Layer Ceramic Chip (MLCC) Capacitors



Vishay’s space capacitors bring an unprecedented level of quality to space and military applications.  Vishay's capacitors are constructed using a reliable Noble Metal Electrode (NME) system of Palladium Silver (PdAg) and are fully qualified to meet the requirements of MIL-PRF-123.  Available in a broad range of capacitance values from 1pF to 470nF and voltage ratings of 50 or 100 volts with operating temperatures between –55 degrees C to +125 degrees C, they are all built upon Vishay’s progressive automotive and medical implant quality disciplines.


Available with 12 week lead time (see matrix below)

Do you need a smaller size capacitor that is not included in MIL-PRF-123 slash sheets, or a higher performance than when MIL-PRF-123 was established?

Today’s designs often require products outside the specifications of Mil-PRF-123: higher capacitance value, smaller body size, or higher working voltage. Vishay Vitramon applies the design constraints and manufacturing processes used for MIL-PRF-123 products to the needs of today’s designers.
