The X7R (Type 2) high voltage, stable ceramic chip MLCC capacitor series from SRT Microcéramique offers a vast range of options to suit any demand, including capacitance between 10pF to 470nF across a range of chip sizes from 1206 to 8060, selection of tolerances (±5%, ±10% or ±20%), voltages (2kV, 3kV, 4kV, 5kV and 10kV) and a wide range of terminations. As with all SRT-MC components, the X7R capacitors are popular in safety-critical industries thanks to their excellent quality and reliability. Their operating temperature is between -55°C and +125°C.

While this capacitor series offers a large number of options, customisation is possible on all SRT Microcéramique components – if none of the options are suitable for your application, please contact us to discuss the custom solutions available.
The dielectric strength test for the X7R capacitors is performed per method 103 or EIA 198-2-E, applying 1.2Un for 5s with 50mA maximum charging current.
Typical applications for the SRT-MC X7R series of high voltage ceramic capacitors include:
