Ceramic Capacitor Vibration

There is almost no noise generated by the capacitor itself.

Ceramic capacitor vibration.

Among failure modes there are open circuit failures and short circuit failures. However when a capacitor is mounted on a board the vibration increases and when the cycle of the amplitude reaches the audible frequency range 20hz 20khz of humans it can be heard as a noise. Take the measures of fixing the capacitor etc. Vibration resistance is also greatly enhanced by the panasonic anti vibration features along with the reduced height volume and weight.

Applications where vibration resistance is critical are becoming more common and manufacturer panasonic is responding with vibration proof components in their capacitor ranges. Ceramic capacitors faq. Singing capacitors piezoelectric effect abstract in some applications design engineers are finding a vibration or low audible hum coming from certain ceramic capacitors. This faq will discuss some aspects of this singing capacitor phenomena.

This is sometimes described as a singing capacitor and is actually a piezoelectric effect. For example the noise sounds like a hum hiss or a. A ceramic capacitor is a fixed value capacitor where the ceramic material acts as the dielectric it is constructed of two or more alternating layers of ceramic and a metal layer acting as the electrodes the composition of the ceramic material defines the electrical behavior and therefore applications. Under the following status the vibration and or shock may be applied to a capacitor.
