For dual-polarity tests, two diodes should be used back to back in parallel. Figure 3. Alternative test circuit that incorporates a small-signal diode Test Hardware Considerations A variety of ...

The intrinsic capacitance of the test circuit is 2.8 pF. Using this correction, the values you obtain on the lowest two ranges are accurate to approximately ±2%, or ±1 pF. You must observe capacitor ...

The capacitor charging and discharging time can be correlated to the duty cycle of the MOSFET gate. Figure 6 shows the voltage behavior across Vcap.

It runs, and confirms his test capacitor is still good. It can’t measure the capacitance, but we’re guessing the resourceful engineer would also have constructed a bridge for that.

TDK released the fully-revised version 4.0 of their Online AlCap Useful Life Calculation Tool for EPCOS aluminum electrolytic capacitors. The tool covers all new high-voltage capacitors (>150 V DC ...
