Product Overview
Description
Teflon woven glass fabric planar resistor copper-clad laminates
F4BDZ294
1.Description:
F4BDZ294 is a kind of Teflon woven glass fabric planar resistor copper-clad laminates with the dielectric constant of 2.94. This high frequency laminate is made of Teflon woven glass fabric(with low dielectric constant and low dissipation factor)and the planar resistor copper foil. It has superior electrical and mechanical performance. Its high mechanical reliability and excellent electrical stability is suitable for the design of the complicated microwave circuit.
