The CG2420LTR is a Gas Discharge Tube Arresters (GDT) device designed to protect equipment from transient overvoltage surges and electrostatic discharge (ESD). It is commonly used in a variety of sensitive analog and digital systems, telecom systems, automotive electronics, and other controlled environments. The GDTs are designed to provide a localized protection at the point of contact between two systems or circuits, and as such are a key component of any effective lightning protection system.

The CG2420LTR is a low voltage rated protector, designed for applications requiring minimum disruption of circuit operation and minimal capacitive loading. GDTs are typically used in a variety of telecommunication systems, such as telephone and data lines, and in motorsports vehicles and other mobile applications. The CG2420LTR is a special class device that is tuned to the line frequency, allowing for low voltage to pass while still providing excellent protection against high voltage surges.

The GDT in the CG2420LTR utilizes three separate mechanisms to provide protection against overvoltage surges. First, it utilizes a Zinc Oxide (ZnO) varistor that is designed to block and absorb transient pulses of energy before they enter the circuit. The ZnO varistor is made of highly conductive semiconductor material, and acts as a resistor when low voltages are applied to it. When a high voltage pulse is applied however, its resistance quickly drops, allowing it to absorb the energy before it is able to damage the system.

Second, the CG2420LTR utilizes a gas tube arrangement that provides a fast response in the event of a high voltage surge. The gas tube contains a mixture of noble gases, which are designed to break down at specific voltages, allowing the gas to conduct and direct the surge current away from the sensitive components. The breakdown voltage of the gas tube is adjustable via a variable gas pressure, allowing the CG2420LTR to be tuned to the specific application and protector voltage.

Finally, the CG2420LTR is equipped with a built-in capacitance for line filtering. This filtering capacitor is designed to reduce electrical noise, improve signal quality, and provide additional protection against high-frequency surges. The capacitance of the CG2420LTR can be adjusted to meet the specific line frequency and voltage requirements of the application.

The CG2420LTR is a versatile and reliable Gas Discharge Tube Arrester device, designed to provide high levels of protection with minimal disruption to the circuitry. Its fast response time and adjustable gas pressure and capacitance make it well suited for a variety of applications, from telecom systems to motorsports vehicles. The CG2420LTR is a key component in any complete lightning protection system, ensuring the safety and reliability of connected equipment.
