Ceramic chip capacitor high vibration.

Under the following status the vibration and or shock may be applied to a capacitor. 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. Besides these large ceramic power capacitors for high voltage or high frequency transmitter applications are also to be found. By the equipment manufacturer if necessary.

Tdk s soft termination provides very high resistance to mechanical and thermal stress to ensure the component can meet the requirements of its customers. Among failure modes there are open circuit failures and short circuit failures. In higher reliable applications which are exposed to shock and vibration and to extreme temperature swings this can result in higher failure rates in the field for conventional capacitors. Avoiding failures in ceramic chip capacitors shown in also known as multilayer ceramic capacitors mlccs is strongly driven by the ability of the designer both electrical and mechanical to follow guidelines based on an understanding on how surface mount ceramic capacitors fail.

Along with the style of ceramic chip capacitors ceramic disc capacitors are often used as safety capacitors in electromagnetic interference suppression applications. When a crack occurs on the element of an mlcc multilayer ceramic chip capacitor due to depaneling of the print circuit board screw fastening or shock from a vibration or a drop it may lead to a short circuit failure.
