Bourns 2039110BLF Precision Fast Responding GDT
The Bourns 2039-110-BLF is a miniature, through-hole gas discharge tube (GDT) surge protector designed to provide robust protection against transient voltage surges. Featuring a sparkover voltage of 1100V and a compact size of 5mm diameter, it's ideal for board-level protection in high-bandwidth applications like xDSL, cable broadband, and high-speed Ethernet. The GDT acts as a 'crowbar,' creating a short-to-ground circuit when a surge exceeds its breakdown voltage, preventing damage to sensitive components. It returns to a high-impedance state once the surge subsides. The 2039 series offers long and stable life performance and low capacitance, ensuring reliable protection in demanding environments.
