SMD3225 1KA 0.5pF 1210 SMD Gas Discharge Tube Surge Protector Arrestor with A Squared Surface Mount Package
Description of SMD3225 1KA 0.5pF 1210 SMD Gas Discharge Tube Surge Protector Arrestor
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. SMD3225 Gas Discharge Tubes (GDT) series has a surge rating of 1kA, 8/20μs.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.
SMD3225 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.
