6 FAQs about [Vcc energy storage capacitor]

What are energy storage capacitors?

What is VCC in MLCC?

Do MLCCs lose capacitance at rated voltage?

Some MLCCs may lose 10% capacitance at rated voltage, while another MLCC of the same case size may lose 70% at rated voltage. Two factors influence VCC: Applied Voltage – As voltage increases on an MLCC, higher electric fields are present on each active layer. Therefore, as voltage increases, capacitance loss also increases.

What happens when a capacitor is charged to V1?

In the picture on the left, capacitor C1 is charged to V1 and establishes a charge Q1. Since ESD sources (such as the human body) have a relatively low capacitance, the resulting charge Q1 will also be low. When the switch is closed, C1 is discharged into C2 (which represents an MLCC used to suppress ESD transients).

When does VCC occur?

This effect is most noticeable when operating at voltages close to the rated voltage and where high capacitance is a critical parameter in the design. VCC occurs in all Class II and Class III -X7R, X5R, Y5V, Z5U, etc.- capacitors from any manufacturer and is related to the design and material properties of the MLCC. What Causes VCC?
