Littelfuse, Inc. (Chicago, IL) has 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.
