Electrolytic Capacitor Testing At Cycles

Capacitor Testing Bridge Schematic

Current 11ETMA standards call for the measurement of electrolytic capacitors at 120 cycles. As a result, a number of our customers have requested modification of the Type 1611-A Capacitance Test Bridge to permit measurements at this frequency. The inclusion of a 120-cycle source for use over the entire capacitance range of this bridge would require substantial and expensive alterations. Relatively minor and inexpensive changes, however, make possible the use of an ex- ternal 120-cycle source...
