SMD4042 800V 1000V 0.8pF Gas Discharge Tube Surging Protector Arrester 3KA For General Telecom Equipment
Description of SMD4042 800V 1000V 0.8pF Gas Discharge Tube 3KA
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. SMD4042 Gas Discharge Tubes (GDT) series has a surge rating of 3kA, 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.
SMD4042 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.
