USB 3.0 Micro B Cable

The USB 3.0 Micro B Cable from TLD Electronic, a China cable manufacturer and factory, is built for compatible devices requiring standard Type-A to Micro-B connections. It uses 28AWG conductors, dual-layer foil and braided shielding for 90Ω differential impedance. Its design provides a practical option for connecting portable drives, Android phones, Raspberry Pi, and controllers. OEM and wholesale are available.

Product Specifications

Key Features & Benefits

1. 5Gbps SuperSpeed – 10x USB 2.0

The cable supports USB 3.0 throughput. A 4GB 4K video clip transfers from a portable SSD to a laptop in about 8 seconds, compared with over a minute on a USB 2.0 Micro-B cable.

In lab tests with a Samsung T5 SSD and a Windows PC with a USB 3.0 port, read/write speeds exceeded 420MB/s.

2. Sync and Charge at the Same Time

The cable uses 28AWG power conductors for VBUS and ground. It carries up to 0.9A with low voltage drop over the 6ft length. A smartphone or tablet can transfer files and charge at the same time.

3. USB 3.0 Micro-B Compatibility

The USB 3.0 Micro-B connector is used on:

Portable storage: WD My Passport, Seagate Backup Plus, Toshiba Canvio, Samsung T3/T5 older models

Android smartphones and tablets with USB 3.0 OTG support

Gaming: PS4 DualShock 4 wired connection, Xbox One controller PC sync, some Nintendo Switch third-party docks

Single-board computers: Raspberry Pi and SBCs using Micro-B 3.0 for USB-OTG

Optical drives: external DVD/Blu-ray burners from LG, ASUS, Pioneer

Audio: portable DACs and MIDI controllers

Industrial and medical: handheld scanners, portable ECG monitors, field data loggers

4. Dual-Layer Shielding

The cable uses 100% aluminium foil plus 64-braid tinned copper mesh. In anechoic chamber tests, signal-to-noise ratio improved by 20dB compared with single-shielded cables. This supports stable data transfer near Wi-Fi routers, Bluetooth transmitters and power adapters.

5. Construction for Daily Use

5,000+ insertion/withdrawal cycles

8,000+ bend cycles at 180°

Nickel-plated brass connector shells

30mm overmoulded strain relief at both ends

In a field test with a location sound recordist using the cable daily, it outlasted three generic cables over a 14-month period.

6. Backward Compatibility

The cable works with USB 2.0 Micro-B ports. The connector fits, and the device operates at USB 2.0 speeds. This allows one cable to be used for older phones, older portable drives and legacy peripherals.

Application Scenarios

Field Data Backup Connect a portable HDD to a laptop at a remote shoot location. Transfer RAW images in minutes.

Phone-to-PC File Sync Transfer video files, music libraries or app backups from Android phones to a computer.

Gaming Stations Connect PS4/Xbox controllers to a PC for wired gaming.

Single-Board Computer Prototyping Link Raspberry Pi or Arduino boards to laptops for programming, serial monitoring and power.

External Optical Drives Connect DVD/Blu-ray burners to laptops without integrated drives.

On-the-Go (OTG) Productivity Connect USB drives, keyboards or mice to Android tablets.

Industrial Data Harvesting Use with portable data loggers in manufacturing or environmental monitoring.

Studio Monitoring Connect portable DACs and headphone amplifiers to laptops.

Technical Construction

SuperSpeed Pair Routing Inside the Micro-B moulding, a small PCB routes traces to connect the 10-pin plug to the cable wires. SSTX+/- and SSRX+/- pairs are separated from VBUS and ground. Trace lengths are matched to keep differential pair skew under 15ps.

Impedance Matching Each batch is tested with a Time-Domain Reflectometer (TDR) to verify differential impedance of 90Ω ± 5Ω across the cable length. TDR plots show a flat profile.

Shielding Continuity The braided shield is soldered directly to the connector shell at both ends. This provides a low-resistance connection to ground.

Power Conductor Sizing 28AWG power conductors deliver 0.9A with less than 0.2V drop over 6ft.

100% Electrical Testing Each cable is tested for:

Continuity on all 10 pins

Short-circuit isolation

Hi-Pot insulation: 300V DC, >10MΩ

Attenuation at 2.5GHz: <12dB/m

Real-device handshake and speed verification

Client Testimonials

DataVault Systems (UK) “We standardised this Micro-B 3.0 cable with every portable drive we sell. In 18 months, we’ve had less than 1% failure rate. Customers mention the cable does not fail after a few months. It has become a selling point for us.”

Studio86 Productions (Australia) “Our video editors use these cables to offload footage from Samsung T5 drives in the field. Previous cheap cables degraded speed over time. TLD’s maintains full 5Gbps after months of heavy use. We now order 200 units per quarter.”

MobileGear (USA) “We added this Micro-B cable to our catalogue. Our return rate is under 0.3%, compared with 5–8% on the previous supplier’s cable. Customers leave reviews mentioning ‘solid build’ and ‘works every time’.”

TechLab Innovations (India) “We use these cables with Raspberry Pi and Arduino kits. Students are rough on equipment. We’ve had fewer than 5 failures out of 500 cables over an academic year. We’ll place a larger bulk order next semester.”

FAQ

Q1: What is the difference between USB 3.0 Micro-B and USB 2.0 Micro-B connectors? A: The USB 3.0 Micro-B connector is wider and has 10 pins, compared with 5 pins on the USB 2.0 version. The extra pins carry SuperSpeed TX/RX signals. A USB 3.0 Micro-B cable fits into a USB 2.0 Micro-B port, and the device operates at USB 2.0 speeds. A USB 2.0 Micro-B cable does not fit into a USB 3.0 Micro-B device port because the port opening is wider. This cable covers both scenarios.

Q2: Will this cable charge my Android phone while transferring data? A: Yes, if your phone supports USB 3.0 OTG and the host port delivers at least 0.5A. The 28AWG power conductors reduce voltage drop, so the phone charges at a usable rate while syncing. For fast-charging protocols such as Qualcomm Quick Charge or USB PD, a dedicated charger is required. For standard USB bus power, this cable works.

Q3: What length options are available, and does length affect speed? A: Standard stock lengths are 3ft and 6ft. Custom lengths from 1ft to 15ft are available for bulk orders. Lengths under 10ft deliver full 5Gbps performance. Lengths above 10ft have higher signal attenuation, but the conductor quality maintains SuperSpeed up to 15ft. Beyond 15ft, an active extension is recommended.

Q4: Can I get this cable with my company logo and custom packaging? A: Yes. TLD offers OEM and private-label services including laser engraving on the USB-A connector shell, printed branding on the cable jacket, custom colour options and retail packaging design. Minimum quantities for full custom moulding start at 3,000 units. Simpler branding such as labels and printed sleeves starts from 1,000 units.

Q5: How do I request a free sample? A: Email the sales team with your company details and intended application. Free samples are available to qualified businesses; you only pay shipping.

Q6: What is the MOQ for a first-time order? A: Standard MOQ is 500 units for stock models. For customized products (colour, length, packaging), MOQs vary. TLD can often start with 300 units for startups and smaller e-commerce sellers to test the market.
