CGK-500

CGK-500

The Copper-clad laminated circuit board using flouroplastic impregnated glass fabric as the dielectric.
Obtaining characteristics of fluoroplastic, it also has stable permittivity in wide frequency band and a very small dielectric loss tangent in the high frequency band.

Use

Satellite communication/Satellite broadcasting/All mobile communication systems/ETC or AHS in ITS/Regional wireless communications networks (WLL)/ CPU/Measuring instrument/Artificial satellite-mounted device

Operating temperature range

-60°C to +220°C

Structure

CGK-500 Structure

Characteristics

●The small, lightweight, and highly functional circuit with low loss can be obtained by its high dielectric constant.
●It has 5.0 dielectric constant.

*The dielectric constant is assumed to be 5.00. However, the dielectric constant varies with varying thickness.
*The tolerance of the dielectric constant is assumed to be ±0.15 for any one variety.

*As a standard we have used ½ oz. electrolytic copper foil on both sides. For other thicknesses of electrolytic copper foil, copper foil on one side, rolled copper foil, or in the case where other special measurements are necessary, please seek a special consultation from us directly.
