Superior Speed and Signal Strength for Miniaturized Devices

Ideal for a wide range of microminiature data transmission applications, Premo-Flex SlimStack FFC/FPCs support up to 30Gbps data rates using a compact, flexible form factor. The jumpers utilize 0.35mm-pitch SlimStack Flex-to-Board Connectors and offer impedance matching for HDMI (100 Ohm) or USB (90 Ohm) protocols.

Exceptional Signal Integrity

Premo-Flex electromagnetic interference (EMI) protection FFCs are ideal for high-performance or critical applications in noisy environments. These cables help maintain signal integrity by using advanced shielding and first/last pin grounding to minimize interference, ensuring that data transmission remains reliable and accurate.

Connection Security for High-Vibration Environments

Ideal for consumer, industrial and automotive devices subject to high vibration and shock forces, Premo-Flex Superior Retention deliver robust data connectivity for rugged applications. FFC jumpers are available with positive latches to maintain constant connectivity.

Reliable High-Speed Data Transmission for Next-Generation Performance

Supporting high-performance connectivity for devices across numerous industries, Premo-Flex high-speed LVDS solutions use differential pairs of signals to cancel common-mode noise and enhance signal integrity. FFCs with 90-Ohm and 100-Ohm impedance for USB and HDMI are available to support high-speed digital interfaces such as video displays and cameras.

Intermateable Solutions for Faster Time to Market

Premo-Flex FFC Jumpers designed for intermateability with other manufacturers’ connectors enable designers to accelerate time to market by using robust, reliable and high-performance off-the-shelf cables without needing to source or validate new flex-to-board connectors.
