Copper-clad laminates
CGK-500
- Copper-clad laminates
- High Frequency Type
- ROHS Directive
overview
This is a copper-clad laminate with a dielectric material of glass cloth impregnated with a special filler fluoroplastic retaining the properties of fluoroplastic, it has a stable dielectric constant over a wide frequency range and an extremely small dielectric tangent over a high frequency range.
Applications
Satellite communications/Satellite broadcasting/Various mobile communication systems/ETC and AHS in ITS/Local wireless communication networks (WLL)/CPU/Measuring instruments/Satellite-mounted equipment, etc.

*The standard dielectric constant is 5.00, but the value varies depending on the thickness.
*The standard tolerance for dielectric constant is ±0.15 for each type.
*The standard copper foil is 1/2oz and 1oz electrolytic copper foil on both sides, but if you require electrolytic copper foil of other thicknesses, single-sided copper foil, rolled copper foil, or special dimensions, please contact us separately.
