Product Overview

The CG21000L is a Gas Plasma Arrester that provides a high degree of surge protection in a small size ideal for board level circuit protection. GDTs function as switches which dissipate a minimum amount of energy and therefore handle currents that far surpass other types of transient voltage protection. The gas-filled, rugged ceramic metal construction makes them well suited to adverse environments. The CG2 series comes in a variety of forms including surface mount, core, straight and shaped leads to serve a variety of mounting methods. The CG2 series (145 to 1000V) is ideal for protecting equipment where higher voltage limits and holdover voltages are necessary.
  • Rugged ceramic-metal construction
  • <1.5pf Low capacitance
  • Meets REA PE 80 standard
