SRT Microcéramique SMD High Voltage Class I Capacitors

SRT Microcéramique’s SMD High Voltage Class I Capacitors offer exceptional stability and performance for high-voltage precision applications where electrical consistency and reliability are paramount. Utilizing ultra-stable Class I dielectric materials such as NP0, N2T, and N750, these multilayer ceramic capacitors (MLCCs) are designed to deliver minimal capacitance drift over temperature and frequency, ensuring reliable operation in the most demanding environments. They are available in capacitance values from 0.1pF to 1µF and support voltage ratings from 1KV to 15KV, making them ideal for high-frequency and high-voltage analog and RF circuitry.

With low dissipation factors (≤0.1%), high insulation resistance (≥10⁵ MΩ or 1000Ω-Farad), and tight capacitance tolerances down to ±0.1pF, these capacitors are engineered to maintain signal integrity and minimize energy losses. The use of Class I dielectrics results in negligible aging, excellent linearity, and predictable temperature coefficients—as low as ±30ppm/°C, depending on the material—making them a strong fit for applications requiring precise timing and frequency control.

Packaged in industry-standard SMD case sizes (such as 1210, 1808, and others), these capacitors are tested to CECC 32100 standards and can be supplied in AEC-Q200-qualified versions for automotive-grade applications. Their robust construction allows for operation from -55°C to +125°C, with high thermal and mechanical reliability under vibration, thermal cycling, and high-voltage stress conditions.
