Measurement of DC Voltage Bias Characteristics in Multilayer Ceramic Capacitors (MLCCs)

The capacitance of multilayer ceramic capacitors (MLCCs) becomes higher. Additionally, the components are frequently considered as an replacement to tantalum capacitors and electrolytic capacitors due to their small size. In such substitutions, the voltage characteristic of capacitance merits caution as an MLCC characteristic.


Q. What instruments can be controlled?

It is possible to control almost any measuring instrument as long as it has a communication interface.
