The Bourns 2026 series gas discharge tubes (GDTs) provide robust surge protection for sensitive electronic circuits. These 3-pole devices are ideal for applications in telecommunications, industrial, commercial, and consumer electronics, as well as aircraft and military electronics. The 2026-40-C2LF model offers a DC sparkover voltage of 400V and is designed with a balanced TRIGARD structure for reliable performance. An optional Fail-Short device is available for enhanced safety, activating at 215°C to provide a high-current path to ground in case of thermal overload. These GDTs are crucial for protecting against voltage surges and ensuring the longevity of electronic equipment.
