The X7R stacked chip capacitor series from SRT Microcéramique offers switch mode power capacitor capabilities for input and output filtering, available in four variants (see Images for the drawing). The series features a wide range of options to suit any demand, including capacitance between 1.5µF to 36µF across a range of chip sizes from 1812 to 8060, a selection of ±5%, ±10% or ±20% tolerance and voltage options (50V, 100V, 200V, 250V, 300V, 500V, 1kV or 2kV). As with all SRT-MC components, the X7R capacitor stacks are popular in safety-critical industries thanks to their excellent quality and reliability. Their operating temperature is between -55°C and +125°C.
