Würth Elektronik: Intelligent Power Supply and Charging Interface

Estimated reading time: 1 minute

Just in time for EU interface standardization, Würth Elektronik presents its new USB socket WR-COM USB 3.1 PD Type C – Power Only SMT. Used exclusively for power transmission, it supports the USB Power Delivery (USB-PD) communication protocol for adaptive charging up to 240 W.

By the end of 2024, the proliferation of charger types for small electronic devices will come to an end. The EU is making USB-C connectors and the USB Power Delivery standard mandatory across the board.

The new USB-C socket from Würth Elektronik, designed exclusively as a power supply and charging interface, meets the new standard. It communicates with the power supply and automatically determines the maximum charging power. In EPR (Extended Power Range) mode, up to 240 W flows into the batteries. Intelligent communication ensures particularly short charging times and prevents damage to circuits due to excessive currents.

Robust, easy-to-install design

For mechanically and electrically reliable installation, the six-pin socket is designed as a horizontal receptacle SMT component with six solder pins: four pins for power supply (Vbus and GND) and two for communication to determine the operating voltage (CC). The contacts come with a nickel barrier layer and a flash gold coating. A nickel coating provides the shielding plating (housing) with high corrosion protection. The thermostable LCP (Liquid Crystal Polymer) plastic parts used are suitable for the reflow soldering process. Moreover, the LCP is ideally suited for the high demands of mechanical durability required by the USB standard.

The intelligent USB socket is used wherever the USB interface is used only for power transmission, for example:

• Industrial PCs and laptops
• Displays
• Mobile input devices
• Handheld controllers
• Power banks
