DC-3GHz TNC Female To Female Connector RF Lightning Arrester Gas Tube Discharge 90V 230V 350V TD-FDT-JK-7-2

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).

Description

Product Overview

 

The model of gas discharge tube arrester is TD-FDT-JK-7-2.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).

Leakage Current

 

The leakage current of a GDT under normal operating conditions should be as low as possible to ensure long-term circuit stability.

 

Size and Mounting Method

 

Select an appropriate package size (such as axial, surface mount, etc.) based on the actual application scenario, while also considering board space and thermal management considerations.
