Solid-Core Flexible Microwave Cables Molex Temp-Flex Solid-Core Flexible Microwave Cables are insulated with a patented fluoropolymer dielectric. A helically wrapped foil shield and braid are applied to the cable. A 70% velocity of propagation (VOP) loss characteristic is achieved with a solid FEP dielectric around the center conductor and 85% VOP is achieved with the addition of monofilaments wrapped around the center conductor with an FEP dielectric layer applied over the monofilaments. Molex Temp-Flex Solid-Core Flexible Microwave Cables are compatible with standard 047 connectors (29AWG) and 141 connectors (19AWG).
