Guide to ESD countermeasures for TDK''s Multilayer Ceramic Chip Capacitors (MLCCs). The first step is to confirm how much ESD protection is required. Keep in mind that a 12,000V module level requirement does not mean that the component requirement is also 12,000V.

Input Capacitor Selection The first objective in selecting input capacitors is to reduce the ripple voltage amplitude seen at the input of the module. This reduces the rms ripple current to a level which can be handled by bulk capacitors. Ceramic capacitors placed right at the input of the regulator reduce ripple voltage amplitude. Only
There is a common rule of thumb that the ceramic capacitor voltage rating rule should be derated by at least 25% as standard, but in environments where they will be exposed to voltage ripple effects, this should
Ceramic capacitors can burn due to excessive heat generation, typically caused by: Overvoltage: Applying a voltage exceeding the capacitor''s rated voltage stresses the dielectric, leading to increased leakage current and excessive heat. High Current: High current flow through the capacitor, often due to short circuits or other circuit faults, can generate
This Product Selection Guide contains information to help select products in the Ceramic Capacitors category on DigiKey A capacitor is a passive electronic device that stores electric charge. Ceramic capacitors consist of two or more alternating layers of ceramic material as the dielectric and metal layers acting as the non-polarized electrodes. Applications
Note that the rated voltage of low-voltage ceramic capacitors is determined by their polarization characteristics and is not related to electrical breakdown that is typically 10 to 100 times greater than VR. This allows performing HALT at extremely high voltages compared to the rated Recommendations for selection of commercial MLCCs: 1

In a worse-case scenario, poor capacitor selection can result in a good voltage regulator becoming unstable and failing prematurely. Choose ceramic capacitors with a voltage rating of at least 1.5 times the maximum-input voltage. If tantalum capacitors are selected, they should be chosen with a voltage rating of at least twice the maximum
