Product Details

SMT Quadrate Ceramic Tubes

The quadrate metalized ceramic tube is propitious to apply in SMT smooth surface.It mainly applies for SMD gas tube arresters.

Metalized ceramic can be applied in the production of porcelain controls, surge arresters, surge arrester with insulation,

high temperature resistance, good air tightness, fast heat dissipation, high mechanical strength and high stability in harsh

working environment, good soldering and solder with gold, silver, copper, nickel and so on.

Characteristics of Metallized ceramic :

High mechanical strength High dielectric strength

Low loss in high frequency Low gas leakage coefficient

Low dielectric constant High voltage resistance

Good dimension Convenient soldered
