MLVB Multilayer Varistor ESD Suppressors Bussmann/Eaton MLVB Multilayer Varistor ESD Suppressors are designed to protect electronic circuits from ESD damage. These devices are offered in small 0402 and 0603 sizes, making them ideal to incorporate into any circuit board design. These suppressors are suitable for push-button, power line, and low-frequency overvoltage protection. Bussmann/Eaton MLVB suppressors have the low capacitance necessary to protect a wide range of data speeds, including protection against high-speed transient voltages.
