RC snubber capacitance, resistance, and loss
Example entered 40 nF
Damping uses the capacitance you enter. Zeta 0.7 to 1.0 is a usual range, not a stored row.

Energy calculation
Energy capacitance 40 nF
C_energy = (L_H * I^2) / Delta_V^2. The inductance unit is converted to henry before this equation.
Selected capacitance
Capacitance used 40 nF
Energy mode uses C = (L * I^2) / Delta_V^2. Entered mode uses the capacitance and unit you selected.
Damping resistance 10 ohm
R = 2 * zeta * sqrt(L / C)
Loss
Resistor loss 8 W
P = C * V_peak^2 * f_Hz. Hz, kHz, and MHz are converted to hertz first.
dv/dt and time
dv/dt 250 V/µs
dv/dt = V_peak / (R * C) in V/s, shown as V/µs (volts per microsecond).
Minimum on time 1.2 µs
t_on = 3 * R * C, shown in µs (microseconds).
Zeta from 0.7 to 1.0 is a usual damping note, not a clamp. The AC power equation is not used because X_c is not defined.
