Effective Electrolytic Capacitors Testing with LCR Meters

Application Notes

With increased requirements for size reduction and higher reliability design, it is becoming necessary to evaluate electrolytic capacitors employed in electronic equipment. Production volume has been increasing for circuit applications. Manufacturing and QA now have to improve their testing of electrolytic capacitors. Here are the solutions offered by the Keysight Technologies, Inc. 4263B LCR Meter to meet these measurement requirements.

 

Current Problems in Electrolytic Capacitor Evaluation

 

When making electrolytic capacitor measurements using conventional LCR meters, there are quite a few shortcomings.

  1. Impedance value of the electrolytic capacitors is usually so low that an accurate measurement is hard to achieve. Some LCR meters cannot measure above 20 mF due to a limited measurement range.
  2. Electrolytic capacitors are currently tested at 100 Hz or 120 Hz. The measurement speed at those frequencies is quite slow, and higher throughput cannot be achieved by automatic measurement systems.
