Features, Applications

Description

The Littelfuse SH Gas Discharge Tubes (GDT) series provides high levels of protection against fast rising transients caused by lightning disturbances. It has a surge rating 5kA, 8/20s. Offered in a Squared Surface Mount package, which helps to make pick and place on PCB process easier. This GDT series is perfectly suited for broadband equipment applications. The GDT's low off-state capacitance is compatible with high bandwidth applications and this capacitance loading value does not vary if the voltage across the GDT changes.

The Littelfuse SH Gas Discharge Tube (GDT) series are specifically designed for protection of electrical, multimedia, and communication equipment against over voltage transients in surface mount assembly applications.

Features

Excellent response to fast rising transients GHz working frequency 5kA, 8/20s surge capability as defined by IEC 61000-4-5, 2nd Edition UL Recognized

Applications

Offered with squared body package Non-Radioactive Ultra Low capacitance (<0.7pF) Lead-free and RoHS compliant

CATV equipment Antennas RS 485 Telecom Base Station Power Supply AC Main G.fast EV power Charging Inverter/Variable Frequency Drivers (VFDs)

IEEE 802.3 compliant Ethernet interfaces Broad Band equipment xDSL, ADSL, ADSL2, VDSL, and VDSL2 Medical Electronics Test Equipment General Telecom Equipment Renewable Energy
