Measurement of internal inductance of capacitors by ramp pulse response technique

Experiments were carried out to measure the internal inductance of a capacitor by the ramp pulse method. It is demonstrated that the minimum width of the excitation pulse should be at least 10 times larger than the R/sub i/-C/sub t/ time constant. Care must be taken to minimize the extraneous signal pickup within the test circuit, and every lead must be as short as possible and shielded. It is also shown that suitable calibration should be carried out with noninductive resistors.<>
