2RA-8T2 Series Gas Discharge Tubes GDT 5KA 3.0pF Surge Protector Ceramic Gas Tube Arrester
Description
Using the technical requirements of the leading industry, we
have designed a super thin gas discharge tube, which is mainly
used in the product's volume requirements and space constraints.
Gas discharge tubes (GDT) use noble gasses enclosed in ceramic
tubes to provide an alternate circuit path for voltage spikes. The
ceramic envelope and with nickel connectors allow for high loads.
2RA-8T Gas Discharge Tubes (GDT) series has a surge rating of 5kA,
8/20μs. 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.
Features
Excellent response to fast rising transients
Stable breakdown voltage
GHz working frequency
8/20μs Impulse current capability: 5KA
Non-Radioactive
Ultra Low capacitance (<3.0pF)
Lead-free compliant
RoHS and REACH compliant
Size: Ф8mm*2mm
Storage and operational temperature: -40~+90°C
Applications
Telecom CPE
Communication equipment
Surge Protective Devices
High density PCB assemblies
