Bourns - Breakthrough GDTs reduce device height by 75% for significantly smaller system designs

Bourns' latest product is a new type of gas discharge tube (GDT) in a breakthrough flat-pack design that sets new standards in volume and space-saving circuit protection design. The two-electrode 2017 type FLAT GDT series uses a breakthrough flat package and horizontal circuit design to meet the more sensitive overvoltage protection requirements of telecommunications and industrial communication equipment, surge protection devices and high density and space-constrained applications in an innovative way. Printed circuit board (PCB) components. Compared with the standard 8mm Bourns GDT, the new series saves 75% in volume. When mounted vertically, the 2017 series can support approximately twice the GDT in the same board space compared to similar board space using a surface-mounted 8mm Bourns GDT. In addition to reducing height and overall volume, FLAT GDT technology also maintains the device's robust isolation and current handling overvoltage protection. This new compact GDT solution provides excellent inrush current ratings, low leakage and insertion loss, and constant capacitance regardless of voltage. These devices also feature voltage-limiting functions optimized for long-term reliability and performance to meet the needs of today's more complex electronic devices, so they do not affect signal or system operation. Bourns Product Manager Kurt Wattelet said, "BournsFLATGDT significantly saves valuable printed circuit board space and helps to solve one of the main problems in high-density application design. It maintains the key features and key protection advantages of traditional GDT technology. .Bourns' engineering team pioneered the next standard for miniaturized circuit protection designs, using a unique isolation path to "compress" the GDT in the axial direction, which has greatly reduced height and volume compared to similarly rated conventional GDTs. " The 2017 model series is an ITU K.12 Class III GDT device with a rated value of 10kA on an 8 / 20μs waveform. This series has a DC breakdown voltage of 90V to 500V. FLATGDT maximizes design flexibility, offers multiple mounting options including bottom-side PCBs, and offers horizontal and vertical surface-mount versions as well as lead-free designs for refill or fixture mounting applications.
