SRT Microcéramique Stacked Capacitor High Voltage 8kV

The SRT Microcéramique Stacked High Voltage Capacitor Series represents a specialized solution for applications that demand high voltage handling, excellent thermal stability, and compact form factors. These capacitors are constructed by stacking multiple multilayer ceramic capacitor (MLCC) chips in parallel, thereby achieving significantly higher capacitance values and energy densities in a single component compared to conventional MLCCs. This configuration also helps minimize equivalent series resistance (ESR) and equivalent series inductance (ESL), making these capacitors especially well-suited for high-frequency and high-pulse applications.

The series supports a wide voltage range from 1kV to 10kV, and capacitance values can span from 12pF up to 39µF depending on the chosen dielectric and stack configuration. These devices are available with a variety of Class I (NP0, N2T) and Class II (X7R) ceramic dielectrics, offering users flexibility in terms of temperature stability, capacitance variation, and frequency response.

All SRT stacked capacitors are manufactured in France and undergo rigorous testing and screening, including a 100% burn-in at 125°C for 48 hours at elevated voltages to ensure long-term reliability. Configurations can be fully customized, including chip size, number of layers, lead style (radial or axial), encapsulation, and termination finish (e.g., solder or epoxy).

These capacitors are an ideal choice for designers working in fields such as aerospace, defence, medical electronics, and industrial power, where reliable operation under harsh conditions and compact, high-capacitance solutions are essential.
