Product pick-up interface Würth Elektronik

Würth Electronics' WR-USB series also offers connectors compatible with USB 3.1. USB 3.1 requires a maximum data transfer speed of 10 Gbps and a power supply of 20V/5A. Furthermore, the connector size has been reduced to the same size as the conventional micro USB connector, which requires not only "communication quality" and "durability" but also "microfabrication technology."

The WR-USB series offered by Würth Electronics offers not only Type-A plugs that can withstand at least 5,000 insertions and removals, but also Type-C plugs that can withstand at least 10,000 insertions and removals. You can choose the product lineup that best suits your application. The WR-USB series has three major features.

1. Extensive line-up for all kinds of solutions

We have a wide range of products to suit each purpose, allowing you to select the optimal product for your development application.

Here we will explain four types.

Type-A USB 3.1 Standard-A type
Type-C USB 3.1 SMT (surface mount) type
Type-C USB 3.1 SMT (surface mount) type
Cables USB 3.1 CAB Assemblies

2. Stable communication quality and smooth large-capacity data larger than high-definition size!

The WR-COM series not only supports high-speed communication with a maximum data transmission speed of 10 Gbps, but also supports a high current supply of up to 20V/5A. This means that a single USB Type-C cable can be used to connect to a 4K display. The WR-COM series from Ultra ElecNix enables large-capacity data transfer with stable communication quality.

3. "Durability" that can withstand plugging and unplugging

The WR-COM series from Würth Electronics offers not only Type-A plugs that can withstand at least 5,000 insertions and removals, but also Type-C plugs that can withstand at least 10,000 insertions and removals.Durability is of utmost importance for USB, which is inserted and removed frequently.

Explaining four product series that support USB 3.1

1. Type-A USB 3.1 Standard-A type

The Type-A connector has a shape almost identical to that of USB 2.0. USB 3.0 and later connectors often have a blue internal resin to distinguish them. Type-A is a connector primarily used for host devices such as desktop PCs, laptops, and media players. Its durability means it can withstand at least 5,000 insertions and removals, making it ideal for desktop PCs and laptops that require frequent insertion and removal.

2. Type-C USB 3.1 THR (through hole reflow) type

The Type-C THR (Through-Hole Reflow) connector is mounted by inserting it into a through-hole on a PCB. It is a PCB connector used to prevent insufficient solder during reflow. It is useful when there is space on the PCB for through-holes. It is "durable" enough to withstand at least 10,000 insertions and removals, making it ideal for laptops, smartphones, and peripherals that require frequent insertion and removal.

3. Type-C USB 3.1 SMT (surface mount) type

The Type-C USB 3.1 SMT (surface mount) type is a connector in which components are soldered (mounted) directly onto the board. Compared to the THR type, which fixes the leads of electronic components to through-holes, it takes up less space. It is "durable" enough to withstand at least 10,000 insertions and removals, making it ideal for laptops, smartphones, and peripheral devices that are frequently inserted and removed.

4. Cable USB 3.1 CAB Assemblies

USB 3.1 CAB Assemblies are cables that support high-speed communication with a maximum data transfer speed of 10 Gbps. Because USB 3.1 can also supply a large amount of power (20V/5A), it is important to choose a high-quality cable.
