The 2R4500T-8T Gas Discharge Tube (GDT) from RUILON is a high-voltage surge protection solution designed to deliver reliable performance in demanding electrical environments. Utilizing advanced ceramic gas discharge technology, this component provides fast and effective protection against lightning strikes, switching transients, and high-energy surge events.
With a DC spark-over voltage of 4500V, the 2R4500T-8T is ideal for applications requiring elevated voltage thresholds compared to lower-rated GDTs. This higher breakdown voltage significantly reduces the likelihood of false triggering while enhancing surge endurance, making it suitable for critical infrastructure and industrial systems. Its high insulation resistance ensures minimal leakage, while low capacitance at 1 MHz supports high-frequency signal integrity.
The device features stable glow voltage and arc voltage characteristics, ensuring smooth transition and efficient energy dissipation during surge conditions. Its high impulse discharge current capability (8/20µs waveform) and strong impulse withstanding voltage performance contribute to extended service life and dependable operation under repeated stress.
Encased in the rugged 2R-8T ceramic package, the 2R4500T-8T offers mechanical durability and easy integration into a wide range of circuit designs. It is widely used in telecommunications, power distribution systems, industrial control equipment, and surge protection modules.
