ST2 Series

High voltage stacked capacitors with 180° solder tabs and a voltage range from 10 to 12 kV and 130 to 1000 pF per disc. Available as standard parts with 4 to 12 stages.

As dielectrics have different temperature coefficients, to choose the best for requirements, please refer to the dielectric curve information and browse the tables below.
