Dielectric Constant (Dk):

The dielectric constant of F4B sheets typically ranges from 2.2 to 2.65; at 10 GHz, the dielectric constant is 2.2 ± 0.02

Dissipation Factor (Df):

F4B sheets have an extremely low dissipation factor, typically ranging from 0.0009 to 0.0030; at 10 GHz, the dissipation factor is only 0.0017

Thickness: Ranges from 0.127 mm, 0.225 mm, 0.3 mm, 0.38 mm, 0.5 mm, 0.508 mm, 0.762 mm, 0.8 mm, 1.0 mm, 1.2 mm, 1.5 mm, 1.6 mm, 2.0 mm, 2.5 mm, 3.0 mm, to 5.0 mm to 6.0 mm.

Dimensions:

Standard dimensions for F4B sheets include 460 x 610 mm, 500 x 600 mm, 850 x 1200 mm, 914 x 1220 mm, and 1000 x 1200 mm.

Non-standard sizes, such as 250×300 mm, 350×380 mm, 500×500 mm, 840×840 mm, and 1000×1500 mm, can also be customized upon request.

Please note that for sheets with a thickness of 4.0 mm or greater, or 0.2 mm or less, the dimensions cannot exceed 500×610 mm.
