The SMD 0603 Series Metal Oxide Varistors are surface-mount surge protection devices engineered for compact electronic systems, power modules, and communication ports. With dimensions of just 1.6 × 0.8 mm, they are ideal for space-constrained portable devices and high-speed digital interface protection. Offering ultra-fast response (<1ns), low capacitance, and excellent batch consistency, they are widely used for ESD protection and transient voltage suppression.
SMD 0603 Series is ideal for compact surge and ESD protection in:
