AI Customer ServiceThe ceramic capacitor will develop mechanical cracks as a result of excessive bending. Subscribe to Utmel ! Hello, this is Candy. A ceramic capacitor is a fixed-value capacitor in which the dielectric is made of ceramic material.
The main causes of ceramic capacitor failure are silver ion migration and the resulting accelerated aging of titanium-containing ceramic dielectrics. In the fabrication of ceramic capacitors, some producers have employed nickel electrodes instead of silver electrodes, and electroless nickel plating has been used on the ceramic substrate.
Ceramic capacitors can break out in several ways. They can be mechanically destroyed if there is too much physical stress on the part (for example, if the board is bent too far). Short circuits will form between the layers of the capacitor. In that situation, it works more like a resistor. What makes ceramic capacitors crack?
Risks: A damaged casing can expose the internal components of the capacitor to the environment, leading to rapid deterioration and failure. Appearance: Rust or corrosion on the capacitor’s terminals or casing indicates aging or exposure to harsh environmental conditions.
Chip ceramic capacitors are usually unmarked, because of the practical problems of doing this. However, some end customers, particularly in the automotive industry, prefer capacitors to be marked, so that they can have visual assurance that the correct component has been fitted.
After a number of temperature excursions, for example due to circuit operation, the crack may propagate (Figure 3), creating an open-circuit device. In severe cases, the body of the capacitor may even fall out, leaving just remnants of ceramic surrounded by termination and solder joints.
