The 2R470LB-8TH Gas Discharge Tube (GDT) from RUILON is a high-performance ceramic surge protection device designed to protect electronic systems from transient overvoltage events such as lightning strikes and switching surges. With a 470V DC spark-over voltage, this component is ideal for medium- to high-voltage applications requiring stable and reliable protection.
Built using advanced gas discharge technology, the 2R470LB-8TH delivers stable impulse spark-over voltage at 1KV/µs, along with high insulation resistance and low capacitance at 1 MHz, ensuring minimal signal distortion in communication and control circuits. Its capability to withstand high impulse discharge current (8/20µs waveform) ensures excellent surge absorption and long service life.
Compared to lower voltage GDT variants, the 470V model provides enhanced resistance to false triggering in higher operating voltage environments while maintaining effective surge suppression. The 2RL-8TH through-hole package ensures strong mechanical durability and reliable performance in demanding conditions.
This GDT is widely used in telecommunications equipment, power supplies, industrial automation systems, signal line protection, and surge protection devices (SPD), delivering dependable and long-lasting circuit protection.
