K-SIM Capacitor Analysis
The Capacitor Analysis includes design tools that simulate a capacitor’s impedance, ESR, capacitance, inductance, current and voltage, all over frequency as well as capacitance versus DC bias and temperature rise versus ripple current. Each of these plots can be simulated over the user’s application parameters such as DC bias and ambient temperature and with parallel combinations. The tool allows for the export of simulated data in the forms of CSV files, spice models, S2P files and picture images.
K-SIM Film Capacitor Lifetime Analysis
The Film Capacitor Lifetime Analysis calculates the estimated life of film capacitors by considering the user’s applied voltage, ambient temperature and relative humidity.
K-SIM Inductor Analysis
The Inductor Analysis includes design tools that simulate an inductor’s inductance, power loss (DC, AC, core, total) and temperature rise, all over current. Each of these plots can be simulated over the user’s application parameters frequency, Vin, Vout, Iout and ambient temperature. The tool allows for the export of simulated data in the forms of CSV files, spice models, S2P files and picture images.
K-SIM Ceramic Aging Analysis
The Aging Analysis for Ceramic calculates the capacitance loss of Class II or Class III capacitors over time due to aging by considering the capacitor's referee time, factor (aging rate), nominal capacitance, and tolerance as defined in the datasheet.
Aluminum Electrolytic Capacitor Lifetime Analysis
The Aluminum Electrolytic Capacitor Lifetime Analysis calculates the estimated life of snap-in, press-fit and screw terminal capacitors. The mission profile of the design is introduced in the Ripple Current Calculation Method which predicts the expected lifetime of the capacitor based on the user’s operating conditions including ambient temperature, operating voltage, air speed and ripple current at specific frequencies. Then, measurements from the prototype design can be entered into an excel template sheet that is exported from the Ripple Current Calculation Method and be reimported into the analysis tool’s Temperature Calculation Method to produce a new lifetime calculation from real measurements.
FIT & MTBF/MTTF Analysis
KEMET’s FIT & MTBF/MTTF Analysis uses the failure rate model per MIL-HDBK-217F to calculate a capacitor’s failures in time (FIT) and mean time between failure (MTBF) / mean time to failure (MTTF) considering the capacitors failure rate and the user’s application environment such as ambient temperature and applied voltage with environmental and circuit conditions.
