1. Introduction of RO4003C

Rogers RO4003C, a woven glass - reinforced hydrocarbon/ceramic material, marries the electrical prowess of PTFE with the ease - of - manufacturing of epoxy/glass. This material delivers outstanding high - frequency performance and low - loss traits, rendering it perfect for applications like RF microwave circuits, matching networks, and controlled impedance transmission lines. Presented in multiple configurations featuring 1080 and 1674 glass fabric styles, every variant adheres to the identical electrical performance standards. Available in various configurations, RO4003C laminates use 1080 and 1674 glass fabrics, all meeting the same electrical specifications. RO4003C materials are non - brominated and non - UL 94 V - 0 rated.
