First Miniature HV SMT Gas Discharge Tube with Two Squared Terminals from Littelfuse Withstands Surges Up to 3kA@8/20μs
2016-10-06 | ReturnCG4 Series Two-Terminal High Voltage Miniature Gas Discharge Tubes are high voltage (800V – 3000V) devices designed for over-voltage protection for high isolation applications. They help protect personnel, equipment and circuitry from abnormally high voltages caused by lightning or electrical transients.
Applications for the CG4 Series GDT include appliances and white goods, such as air conditioning units; industrial systems like high voltage power supplies, variable frequency drivers, and high voltage test equipment; medical electronics, such as NMR medical devices and X-ray machines; and consumer electronics like set-top boxes.
“Gas discharge tubes like those in the CG4 Series dissipate voltage transients through a contained plasma gas. They have high insulation resistance plus low capacitance and leakage to ensure minimal effect on the normal operation of equipment,” said Stephen Li, global product manager for the GDT product line at Littelfuse. “The CG4 Series is the first high voltage miniature GDT from Littelfuse developed to provide a new option for high voltage applications that require the combination of a surface mount form factor and medium surge capability.”
CG4 Series Two-Terminal High Voltage Miniature Gas Discharge Tubes offer these key benefits:
。High (800V – 3000V) DC breakdown voltage provides high voltage isolation, suitable for applications where hi-pot testing is required.
。A miniature footprint in surface mount form factor, which aligns with the trend of using surface mount technology in compact, space-limited applications. Square terminals help improve manufacturing efficiency during the printed circuit board assembly process.
。Medium surge capability (3kA@8/20µs) allows greater design flexibility by offering a new gas discharge tube option for applications with surge protection requirements up to 3kA.
Availability
The CG4 Series is available in tape & reel packaging in minimum order quantities of 2,000 pieces. Sample requests can be placed through authorized Littelfuse distributors worldwide. For a listing of Littelfuse distributors, please visit Littelfuse.com.
