Sonnet Technologies Thunderbolt 5 Cable 0.3m

SKU CH-5KF5-TJQ6D

Thunderbolt cable delivers 80 Gbps data and 120 Gbps video bandwidth with 240 W power delivery in a .3 m length

  • 80 Gbps bi-directional data transfer accelerates professional file workflows
  • 120 Gbps video bandwidth drives one 4K @540Hz or two 8K @60Hz displays
  • 240 W PD 3.1 charging powers high-performance laptops through a single cable
  • Intel-certified Thunderbolt 5 stability ensures reliable daily operation
  • 3 m length with dual USB-C connectors fits compact desktop setups

Professional Workflow Cable

The Sonnet Technologies Thunderbolt 5 Cable 0.3m delivers 80Gbps bi-directional data transfer and 120Gbps video bandwidth for creative professionals moving 4K video and 3D models. Its 240W Power Delivery 3.1 support charges high-performance laptops while driving displays. Intel certification ensures stable operation with Thunderbolt 5, Thunderbolt 4, Thunderbolt 3, USB4 and USB-C devices.

Upgrade From Slower Links

This cable replaces Thunderbolt 4 or USB4 connections limited to 40Gbps when your workflow demands double the throughput for large file transfers or multi-monitor arrays. The jump is worth it if you need one 4K 540Hz display, two 8K 60Hz panels or three 4K 144Hz screens simultaneously. It is not for users staying within 40Gbps bandwidth or charging below 240W.

Simple Locking Connection

Dual USB-C male connectors plug directly into host and peripheral with no driver installation required. ThunderLok-A compatibility adds a mechanical lock on supported Sonnet peripherals to prevent accidental disconnection during intensive sessions. The 0.3m length suits desktop docks but cannot span distant equipment racks. Ensure both endpoints support the target bandwidth and power profile.

Questions about this item

What connector type does this 0.3m Thunderbolt cable use for mounting?

It uses dual USB-C male connectors that plug directly into Thunderbolt 5 ports on compatible devices and peripherals.

How is the cable installed, and what step is often missed?

Simply connect each USB-C end to a Thunderbolt 5 port; the step often missed is ensuring both host and peripheral support Thunderbolt 5 for full 80Gbps speed.

When will this Intel-certified cable need replacement?

Replace it if the connectors become loose, the cable shows physical damage, or connected devices no longer negotiate 80Gbps data or 240W power delivery.
