DC-3Ghz Surge Protector SMA Male To SMA Female Lightning Gas Discharge Tube Arrestor 90V 230V TD-FDSMA-JK-1

The model of gas discharge arrester is TD-FDSMA-JK-1.Gas Discharge Tube Surge Protector utilized a gas-filled discharge tube(GDT). The GDT works as an insulator but can be automatically conductive in very short time when the lightening current flows into the protector, then the lightening current will be diverted to earth via outer contact and grounding means.

Product Overview

 

The model of gas discharge arrester is TD-FDSMA-JK-1.Gas Discharge Tube Surge Protector utilized a gas-filled discharge tube(GDT). The GDT works as an insulator but can be automatically conductive in very short time when the lightening current flows into the protector, then the lightening current will be diverted to earth via outer contact and grounding means. Once the surge subsided, theGDT revert to its original condition, and be ready fornext spark-over.It can work repeatedly if on damage done to the GDT and the maintenance is easy since the GDT is replaceable. It has the characteristics of wide frequency range, low vswR, low insert loss and easy installation.(Some models were developed with CITEL).

Response Time

 

The response time of a gas discharge tube (GDT) is typically in the nanosecond range, which meets most power line protection requirements. However, in scenarios requiring ultra-fast response, other protection components (such as TVS diodes) should be used.

 

Capacitance

 

For high-frequency signal transmission or communication lines, a GDT with a low capacitance (<1pF) should be selected to avoid signal attenuation.
