Offers a new option for high voltage applications that require medium surge capability

 

Littelfuse - CG4 series gas discharge tube

CHICAGO,
IL —
Littelfuse,
Inc.
,
the global leader in circuit protection, introduced its first high voltage, surface-mount
gas discharge tube (GDT) with two squared terminals that is capable of
withstanding surge currents of 3kA@8/20μs in a small form factor.

CG4 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.
