Ceramic Capacitor Vibration

This faq will discuss some aspects of this singing capacitor phenomena.

Ceramic capacitor vibration.

By the equipment manufacturer if necessary. 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. Singing capacitors piezoelectric effect abstract in some applications design engineers are finding a vibration or low audible hum coming from certain ceramic capacitors. For example the noise sounds like a hum hiss or a.

Under the following status the vibration and or shock may be applied to a capacitor. Ceramic capacitors faq. Among failure modes there are open circuit failures and short circuit failures. 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. Since the body of a capacitor consists of ceramic if a mechanical shock is applied directly the capacitor may be damaged and a crack may be generated. Applications where vibration resistance is critical are becoming more common and manufacturer panasonic is responding with vibration proof components in their capacitor ranges. This is sometimes described as a singing capacitor and is actually a piezoelectric effect.
