Please tell me measurement conditions and instruments used to get characteristic data of ceramic capacitors.

Please refer to following explanations.


(1) DC Bias characteristics

(2) Temperature characteristics

Measurement instruments LCR meter HP4284A or E4980A by Keysight Technologies
Temperature chamber HC-360 by ESPEC
Measuring Frequency Class 1
 1MHz±10% (C ≥ 1000pF)
 1kHz±0% (C < 1000pF)
Class 2
 1kHz±10% (C ≥ 10uF)
 120Hz±10Hz (C < 10uF)


(3) Ripple current characteristics

Multifunction generator WF1947 by NF Corporation
Bipolar amplifier HSA4014 by NF Corporation
Infrared thermometer IT2-50 by KEYENCE
Measuring frequency 10kHz, 100kHz, 1MHz
Ambient temperature 25±2℃


Measurement Figure

In measurement system above, the current is increased while measuring temperature of the product and the ripple current value at that temperature. That is done until the temperature achieves 20℃ over the initial state. This procedure is repeated for each frequency specified in the table above.
