Product Description

The 2CPX043390R Varistor (High Voltage Varistor), identified as part number 043390R9999 Resistor, is a robust surge-protection component designed for high-voltage circuits. Operating within a voltage range of 300–1200V AC/DC and a temperature span of -40°C to +85°C, it safeguards industrial power systems, grid infrastructure, and heavy machinery from transient overvoltage events. Key features include a peak current handling up to 10kA, energy absorption capacity of 450J, and sub-20ns response time. Its compact, lead-free design integrates directly into circuit protection modules without additional interfaces. Advantages include exceptional durability under repetitive surges and stable leakage current, while limitations involve gradual degradation under extreme continuous stress. Widely used in energy distribution, manufacturing automation, and renewable energy systems, it eliminates the need for auxiliary components like screens or batteries, focusing purely on voltage clamping efficiency.
