6 FAQs about [Capacitor detinning]

How to derate a ceramic capacitor?

In ceramic capacitors, derating can be achieved by controlling the derating parameters, namely voltage and temperature. Derating is found to be the most effective way to prevent failure as well as parameter drift in ceramic capacitors. It can be done by limiting the applied voltage to around 50% below the rated voltage.

What is the purpose of a capacitor derating?

The purpose of the derating is to reduce amount of load accelerating factors to the capacitors. The two main accelerating factors are voltage and temperature. As per the equation C1-20 energy content is depending to voltage squared, thus voltage reduction (voltage derating) has a significant impact to overall energy handling through the capacitor.

Should a ceramic capacitor be used at a lower voltage?

It is recommended to use a ceramic capacitor at a lower voltage than the rated voltage in order to eliminate the effect of the voltage coefficient of capacitance. Voltage derating is expressed as the percentage of the voltage that is subtracted from the rated voltage.

What is a ceramic capacitor derating voltage?

Why does the capacitance of a ceramic capacitor decrease over time?

The X7R, X5R, and Y5V ceramic capacitors experience a decrease in capacitance over time due to the relaxation or realignment of electrical dipoles within the capacitor. The ceramic capacitance decrease reaches up to 80% at rated voltage. This phenomenon is known as the voltage coefficient of capacitance.

Are ceramic capacitors vulnerable to capacitance degradation?

Ceramic capacitors are vulnerable to capacitance degradation with applied voltage. The X7R, X5R, and Y5V ceramic capacitors experience a decrease in capacitance over time due to the relaxation or realignment of electrical dipoles within the capacitor. The ceramic capacitance decrease reaches up to 80% at rated voltage.
