SRFN300
Product Introduction
The composition of the dielectric layer of the SRFN300 product is PTFE resin and special filler, and the high-frequency microwave substrate reinforced without glass fiber cloth has no glass fiber effect when electromagnetic waves propagate, ensuring frequency stability and the lowest dielectric loss at the same level.
Product Features:
●Dk/Df remains stable at different frequencies and temperatures
●Low dielectric constant 3.0+/-0.04
●Low water absorption rate
●Excellent anti peeling performance
●UL 94 V-0 flame retardant performance
