High voltage chip capacitor material: COG NPO X7R X5R Y5V

NPO (COG) chip capacitor are classified as Class I high-frequency capacitor. Their capacitance is stable and does not change with changes in ambient temperature, voltage and time, and is suitable for high-frequency electronic circuits.

The chip capacitor made of X5R/X7R are classified as type II low-frequency capacitor, their capacitance is relatively stable, and they are relatively sensitive to changes in ambient temperature, voltage and time.

SMD capacitor made of Y5V material belong to Type II low-frequency capacitor, and their capacitance varies greatly by the environment, temperature, voltage and time.

common problem



As the capacitance value of MLCC continues to increase, the equipment used to measure capacitance in the past may not be able to provide accurate measurement of large capacitance components. The meter cannot drive enough AC voltage to measure the full capacitance. The following discussion contains answers to frequently asked questions and measurement tips for high-volume measurement of MLCC.
