Stressed out over capacitor failure - EDN

Web24 aug. 2015 · Multilayer ceramic capacitors (MLCCs) are generally the capacitor of choice for applications where small-value capacitances are needed. They are used as bypass capacitors, in op-amp circuits, filters, and more. Advantages of MLCC include: Small parasitic inductance give better high-frequency performance compared to aluminum … WebOne of the major reasons of ceramic element cracks in MLCCs (Multilayer Ceramic Chip Capacitors) is due to board flexure stress. The crack may lead to a short circuit failure which can cause abnormal heat generation or ignition, therefore, applications which reliability is important absolutely require suitable countermeasures.
