Description
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 100pF to 1.5µF across a range of chip sizes from 0603 to 5440, selection of tolerances (±5%, ±10%, ±20% or -20% to +80%), voltages (200, 250, 500, 630 or 1000V) 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. For the 250Vdc models, 250% of rated voltage is applied; for the 500Vdc model it is a minimum of 150% of the rated voltage and for the 630Vdc and 1000Vdc models the applied voltage is minimum of 120% of the rated voltage.
Typical applications for the SRT-MC X7R high voltage series of ceramic capacitors include:
- Passing
- Coupling
- Filtering
- Blocking
