More Information

Gas Discharge Tubes

Littelfuse Gas Discharge Tubes (GDTs) are designed for high-voltage transient surge protection in small devices. Littelfuse GDTs are designed to dissipate large amounts of energy and are ideal for lightning surge protection. GDTs are widely applied to outdoor telecommunications equipment. These Littelfuse devices are available in leaded and surface-mount configurations.

GTCA28-x-R03 High Voltage Series GDTs

Littelfuse GTCA28-x-R03 High Voltage Series GDTs (ceramic gas discharge tubes) are commonly used to help protect high voltage circuits. They offer a high level of surge protection, low capacitance, and a broad array of break over voltage levels, making them suitable for applications such as branch circuits, medical electronics, and surge protection on power lines. With such features, Littelfuse GTCA28-x-R03 High Voltage Series GDTs can help equipment meet the most stringent regulatory standards.

Industrial Communication & Control

Littelfuse Industrial Communication and Control provides protection for RS-485 and Ethernet applications. The Industrial RS-485 features the capability of driving multiple ports, a fast speed rating of 10Mbps, and a long-distance transmission of 1500. Industrial Ethernet provides a long-distance transmission of 100m, a 30W PoE+ rating, and a fast speed rating of 1Gbps. Littelfuse Industrial Communication and Control RS-485 and Ethernet devices are ideal for energy meters, factory automation, wind control, and human machine interface.

RS-485 ESD, Lightning, & Power Fault Protection

Littelfuse RS-485 ESD, Lightning, and Power Fault Protection feature polymeric positive temperature coefficients (PPTCs) that can protect against short circuit and power crosses. The RS-485 product line includes the resettable PPTCs, TVS diodes, GDTs, and SIDACtor series. The TVS Diode Arrays and SM712 series are specifically designed to protect RS-485 applications from ESD, EFT, and lightning-induced surges. When lightning occurs, the SIDACtor will react by causing voltage to increase across PPTC until GDT fires.

General Port Protection Solutions

Littelfuse General Port Protection provides a wide array of solutions for power and communication ports. Ports need protection from common electrical hazards such as lightning surges, induced power surges, power cross, electrical fast transient, electrostatic discharge, and short-circuits due to aging wire or installation errors. Littelfuse General Port Protection products are ideal for automotive, building automation, consumer electronics, and industrial applications.
