KEMET K-SIM Simulation Tool
KEMET K-SIM Simulation Tool is a simulation tool that aids design engineers in analyzing the performance of capacitors over frequency, temperature, ripple current, and voltage conditions. The capacitor types available in KSIM include Ceramics, KO-CAP, Tantalum, Polymer, Film, and Aluminum Electrolytic. KEMET's KSIM tool uses advanced models based on actual measurements to provide engineers with the most accurate real-world simulations.
