An E-marked cable contains an integrated circuit that communicates its power capabilities to the host, required for currents above 3A.

What are USB Cables components?
USB cables are defined by their protocol version (USB 2.0 to USB4), connector geometry, and power delivery (PD) capabilities. For design, prioritize signal integrity requirements, shielding for EMI, and the physical durability of the connector housing.
How to Choose USB Cables Components
Selecting the right USB cable requires balancing protocol speed, physical form factor, and power requirements.
Protocol & Speed
Match the cable rating (e.g., USB 3.2 Gen 2) to your host and device requirements to ensure data throughput.
Power Delivery (PD)
Verify if the application requires high-wattage charging; ensure the cable is E-marked if exceeding 3A.
Connector Orientation
Choose between standard A, B, Micro, or Type-C based on space constraints and mating cycle requirements.
Environmental Rating
For industrial use, prioritize cables with overmolded strain relief and IP-rated housings.
Cable Length vs. Signal
Longer cables increase signal attenuation; use active cables or repeaters for high-speed data over long distances.
