Prevention of damage to the electronic circuit can be accomplished using multiple suppression devices. Multilayer ceramic capacitors (MLCCs) are one of the solutions used to protect components from ESD damage. Since integrated circuits (ICs) are most prone to damage by ESD, MLCCs are placed close to the board connection contacts or directly next to the IC connections in order to absorb and then level the unwanted voltage spikes.

Multi-layer ceramic capacitors (MLCCs) have been the go-to choice for surface-mounted capacitors due to their many advantages, such as wide available capacitance range, non-polarity, low ESR, and low cost. Most designers know that the effective capacitance of Class II MLCCs can be reduced significantly when dc bias is applied across the capacitor.
