Gas Discharge Tube Arresters (GDT) are important components used in a wide variety of electrical and telecommunications systems to defend against damaging electrical transients. The 2056-09-B3LF series of GDTs from Littelfuse are designed to protect high-flux fields and are perfect for use in open access systems. 

The 2056-09-B3LF series of GDTs from Littelfuse is particularly well suited for applications in medium-voltage telecommunication networks, radio and television broadcasting, and other processes. This specific series of GDTs provides superior surge current and voltage clamping characteristics compared to other similar GDTs in the Littelfuse range. Compared to other products in the 2056-09-B3LF series, it offers better electrical performance and low-surge capability.

The main function of the 2056-09-B3LF is to protect sensitive equipment from high voltage transients caused by lightning or large temporary voltage differences caused by short circuits, overvoltages due to load switching, or other external interference. Specialized arrestors are designed for either AC or DC applications, and require the use of an external lightning conductor for adequate protection.

GDTs are composed of a single tube filled with two electrodes. An electric field is created between the two electrodes and when the threshold voltage is reached, a stream of electrons passes through the tube and interacts with the gas, causing ionization. This ionized gas creates a relatively high current capacity between the two electrodes, dissipating the voltage transient.

The 2056-09-B3LF series is designed with an internal trigger loop over-voltage protection scheme, which quickly activates the protection mechanism when a transient is detected. This internal protection loop ensures a fast response time, as well as a high current rating. 

With its superior voltage-clamping capabilities, low insertion loss, and fast response time, the 2056-09-B3LF is ideal for applications that require high levels of performance and reliability. The GDT is constructed with a robust metal housing that provides excellent insulation and protection for the electrodes, as well as superior vibration dampening. This makes it perfect for use in open access systems, where it is unable to use a lightning protection conductor. 

The 2056-09-B3LF series offers excellent surge ratings, low insertion loss, fast response time, and reliable performance. It is well suited for applications requiring superior voltage-clamping capabilities in open access systems, such as medium-voltage telecommunication networks, radio and television broadcasting, and other processes. It is an ideal choice for electrical and telecommunication applications to ensure the safety of sensitive equipment.
