Some of the benefits we offer

Swiss Made and engineered for precision, our laboratory capacitors feature very low partial discharge values and tight capacitance tolerances to ensure highly accurate and reliable performance. With more than 6,000 units delivered over the past 10 years, they offer a proven track record in demanding testing environments. The integration of series and parallel resistors, a low-voltage part, and an insulated output directly within the capacitor provides a compact, safe, and efficient all-in-one solution.
