CG32.7LTR Description

Short technical summary and product information.

The Littelfuse CG32.7LTR is a two-electrode gas discharge tube (GDT) designed for surge protection and high isolation applications. It features a DC breakdown voltage of 2160V min, 2700V typical, and 3240V max at a ramp rate of 100V/s. The impulse breakdown voltage is 3600V max at 100V/µs and 4000V max at 1kV/µs. With a nominal impulse discharge current of 5 kA (8/20µs, 10 shots) and a maximum surge current of 10 kA (8/20µs, 1 shot), this GDT can handle significant transient events. The device maintains a low capacitance of less than 1.5 pF at 1 MHz, making it suitable for high-frequency signal lines. It offers a high insulation resistance of 10 GΩ minimum at 100V and has a typical arc voltage of approximately 25V at 1A. The CG32.7LTR can extinguish follow-on currents up to 200A. The component comes in a through hole axial cylinder package and is available in tape and reel packaging. It is RoHS3 compliant and rated MSL 1.
