Description
Bourns sets a new industry standard by offering a high current rated 2-electrode GDT in an innovative flat-package design. The Model
2019 Series with FLAT® Technology is an ITU K.12 Class IV GDT device rated at 25 kA maximum on an 8/20 μs waveform, providing
a volume and space-saving solution for high density and space-restricted PCB applications. This surface mount device is available in
a horizontal mounting configuration.
