Introduction
Rogers RO4003C materials are proprietary woven glass reinforced hydrocarbon/ceramics known for their exceptional electrical performance, comparable to PTFE/woven glass, while maintaining the manufacturability of epoxy/glass. This design offers superior high-frequency performance and cost-effective circuit fabrication. RO4003C is a low-loss material that can be produced using standard epoxy/glass (FR-4) processes, making it competitively priced.
These materials possess essential properties required by designers of RF microwave circuits, matching networks, and controlled impedance transmission lines. Their low dielectric loss allows RO4003C to be utilized in applications where higher operating frequencies restrict the use of traditional circuit board laminates. Available in various configurations, RO4003C laminates utilize both 1080 and 1674 glass fabric styles, all meeting the same laminate electrical performance specifications. Importantly, RO4003C materials are non-brominated and do not meet the UL 94 V-0 rating.
