The voltage output for dual DCV01 devices is half-wave rectified; therefore, the discharge time is 1.25 µs. Repeating the previous calculations using the 100% load resistance of 50 Ω (0.1 A per output), the results are:

• τ = 50 µs
• t_DIS = 1.25 µs
• V_DIS = 123 mV
• V_ESR = 0.1 × 0.1 = 10 mV
• Ripple Voltage = 133 mV

In this example, it is the capacitor discharging that contributes to the largest component of ripple. Changing the output filter to 10 µF, and repeating the calculations, the result is that the ripple voltage is 22.3 mV.

This value is composed of almost equal components.

The previous calculations are offered as a guideline only. Capacitor parameters usually have large tolerances and can be susceptible to environmental conditions.
