This educational workbench uses the parallel plate formula in SI units. With six hundred fifty electrodes there are six hundred forty-nine active gaps. Relative permittivity is three thousand two hundred, overlap area one point two five square millimeters, and dielectric thickness point eight micrometers. Its one point two percent electrode offset applies a chosen overlap factor of point nine nine four. The resulting nominal capacitance is twenty-eight point five five nine microfarads. Doubling area doubles capacitance; doubling thickness halves it. These three bars share ten pixels per microfarad. This is a lumped teaching model, not a measured component certificate. The live slider rounds the initialized voltage to three point two volts. Dividing by point eight micrometers gives four volts per micrometer, or point zero four megavolts per centimeter. The source assumes a saturation scale of point two five megavolts per centimeter and a degradation factor one divided by one plus field over saturation to the power one point six. At twenty-five degrees Celsius, nominal twenty-eight point five five nine microfarads becomes effective twenty-seven point one one five. At zero bias the effective value equals nominal. These bars again share ten pixels per microfarad. The saturation law and thermal curve are illustrative assumptions, not universal behavior of all barium titanate capacitors. The displayed field is applied field, despite its exported breakdown field label. The frequency chart evaluates the lumped series R L C impedance. Capacitive reactance is one divided by angular frequency times capacitance. Inductive reactance is angular frequency times inductance. Their difference is squared and added to resistance squared before taking the square root. At resonance the two reactances cancel, so impedance reaches the assumed series resistance. For the initialized parameters that resistance is about one point four three five milliohms. With the source fixed fifty milliwatt heat allowance, square root of power divided by resistance gives about five point nine zero three amps. That is a model limit, not a guaranteed safe current. The illustrative purity, alignment, yield and cost estimates are not supplier quotes. Export the complete specification to inspect the actual assumptions.
