2RB-8T25 2 Electrodes SMD Gas Discharge Tube 10KA 2.0pF GDT For High Density PCB Assemblies
Description of 2RB-8T25 2 Electrodes SMD Gas Discharge Tube 10KA 2.0pF GDT
Using the technical requirements of the leading industry, we has 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.
2RB-8T25 Gas Discharge Tubes (GDT) series has a surge rating of
10kA, 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 of 2RB-8T25 2 Electrodes SMD Gas Discharge Tube 10KA 2.0pF GDT
• Excellent response to fast rising transients
• Stable breakdown voltage
• GHz working frequency
• 8/20μs Impulse current capability: 10KA
• Non-Radioactive
• Ultra Low capacitance (<2.0pF)
• Lead-free compliant
• RoHS and REACH compliant
• Size: Ф8mm*2.5mm
• Storage and operational temperature: -40~+90°C
Applications of 2RB-8T25 2 Electrodes SMD Gas Discharge Tube 10KA 2.0pF GDT
• Telecom CPE
• Communication equipment
• Surge Protective Devices
• High density PCB assemblies
