Flat FPC cable for tight builds

The SMUGDESK 0.5M USB4 flat slim FPC cable uses a flexible printed circuit core that is thinner than standard round cables, letting it route through narrow gaps in docking stations, portable workstations and compact desk setups. It is built for users who need high-speed data, power and video in a single low-profile connection.

One cable handles data power and video

The cable carries 20Gbps bandwidth for large-file transfers and external SSD traffic while simultaneously delivering 100W Power Delivery to charge the host laptop or tablet. It also drives 8K@60Hz or 5K@60Hz video to a compatible monitor, removing the need for separate power and display cables in a minimal USB-C ecosystem.

Low bulk aids airflow and cable management

The ultrathin flat construction adds almost no volume inside a chassis or behind a dock, so it does not obstruct fan paths or trap heat around adjacent components. With no bulky jacket or stiff bends, it stays cool to the touch during sustained 20Gbps transfers and 100W charging sessions, keeping noise and thermal load at baseline levels.

Questions about this item

Does the .5 m length limit 20 Gbps speed under sustained use?

The cable is rated for 20 Gbps at .5 m and meets the USB4.0 specification for that length.

Does the flat FPC design run hotter or draw more power during all-day operation?

The thin flat construction does not increase heat or power draw; it simply carries up to 100 W PD and 20 Gbps within normal cable limits.

Must my laptop and dock both support Thunderbolt to use 8K@60 Hz video?

Yes — 8K@60 Hz output requires host and display devices that support the necessary video bandwidth over Thunderbolt or USB4.0.
