ABSTRACT:
For recognizing the polarity of polarized capacitors, their capacitance is measured with an alternating voltage which is superposed with a positive dc voltage and than a negative dc voltage of equal amount. Since a polarized capacitor comprises a lower capacitance given a correct poling than it does given an incorrect poling, the polarization of the capacitor can be indentified from the difference between the two measured capacitances. In particular, the polarity of tantalum or aluminum electrolytic capacitors in the automatic equipping of printed circuitboards or ceramic substrates can be recognized with this method.
