High-surge SMD varistors offer the same electrical performance as leaded varistors. However, they are designed to significantly save space on the PCB.
Commonly used leaded varistors are through-hole components occupying both sides of the PCB, whereas the new SMD is mounted on one side only, leaving space for other components to be mounted on the opposite side of the PCB.
TDK offers various types of high-surge SMD varistors to meet a wide range of requirements and to find the perfect solution for the customer. They also come in two different orientations: horizontal and vertical.
