RIVERSIDE, Calif. - Bourns, Inc., expanded its standard-setting line of volume and space saving FLAT gas discharge tube (GDT) surge arrestors. The Model 2018 Series FLAT GDT is a 3-electrode device that delivers a low profile solution for high density and height-restricted PCB-based applications. The new series is lighter weight with a 50 % height reduction compared to standard 8 mm Bourns GDTs. Bourns designed this latest series as a surface mount device with a large top flat surface, making it ideal for vacuum head pickup in today's high-speed pick and place manufacturing.
The Bourns FLAT GDT Model 2018 is an ITU K.12 Class III device rated at 20 kA¹ on an 8/20 µs waveform. The series is offered with DC breakdown voltages ranging from 90 to 500 V and features an innovative flat design that reduces the height of the Bourns GDT from a typical 8 mm to a low profile of 3.5 mm.
"Besides saving valuable PCB space, these new 3-electrode FLAT GDT devices help to reduce component count in space-constrained designs. The series provides the ability to protect both Line to Ground and Line to Line with a single Model 2018 FLAT® GDT, which previously required two GDTs," said Kurt Wattelet, product line manager at Bourns, Inc. "As a 3-electrode GDT, transverse voltage limiting performance is enhanced with the ability to share a common center electrode designed to allow both sides of the GDT to turn on quickly resulting in balanced operation."
