The 2R470TB-8T2 Gas Discharge Tube (GDT) from RUILON is a high-performance ceramic surge protection device engineered to protect electronic systems from transient overvoltage and lightning-induced surges. Featuring a 470V DC spark-over voltage, this GDT is ideal for high-voltage applications where stable and reliable protection is critical.
Designed with advanced gas discharge technology, the 2R470TB-8T2 offers precise impulse spark-over voltage at 1KV/µs, high insulation resistance, and low capacitance at 1 MHz, ensuring minimal signal distortion in sensitive circuits. Its capability to withstand high impulse discharge currents (8/20µs waveform) provides excellent surge absorption and long operational life.
Compared to lower voltage GDT variants, the 470V model significantly reduces the chances of false triggering in higher working voltage environments, making it highly suitable for industrial and power-related systems. The robust 2RT-8T2 through-hole package ensures strong mechanical stability and reliable performance under demanding conditions.
This component is widely used in power supplies, telecom infrastructure, industrial automation systems, surge protection devices (SPD), and energy management systems, delivering dependable protection and enhanced system reliability.
