Thin Wireless Coils with High Q Factor for Compact Devices

Molex has introduced a new series of standard and custom wireless power coils based on NuCurrent technology for plug-free device charging. The PowerLife standard and custom wireless power coils feature a thin design with high power transfer efficiency (Q-factor).

Smartphones, tablets and wearable devices are becoming thinner and lighter, but the need to balance this trend with higher Q performance, required for wireless charging leads to increased thickness and size. This places limitations on device designers as internal real estate shrinks. The PowerLife standard and custom wireless power coils offer device OEMs a compact coil with what MOLEX claims to be the highest Q in the industry for etched circuitry. As a result, designers will be able to offer wireless charging while still meeting marketplace demands for compact devices.

The PowerLife wireless power coils support low, high and proprietary frequencies, in standard and custom sizes. A high Q-factor results in lower heat generation and faster charging in a range of applications, including mobile phones, tablets, gaming systems, wearables and other consumer electronics, medical devices, furniture, and in-vehicle transmitters. A logical next-step in connectivity, wireless power requires the right technologies to achieve optimal device charging. These compact PowerLife wireless power coils provide an extremely tight electrical tolerance and low rate of field failures for a better product design, performance and end-user experience.

Traditional wire-wound coils have dominated the marketplace so far, but they require wide electrical tolerances. Also, they are difficult to integrate with the system, especially into products that require thin designs and are less reliable due to secondary connections and susceptibility to heat, vibration and shock. High-efficiency PowerLife coils withstand vibration, heat and humidity, and excel in transmitting power through air, wood, or any non-metallic surface. The longevity and robustness of these coils will make them ideal for in-vehicle, industrial and medical applications.

Available in virtually any size, PowerLife coils accommodate single or multiple frequencies in one assembly for reduced component count. Molex manufacturing resources support different volume requirements. Off-the-shelf receivers with single and multiple frequencies can be provided for engineering evaluation and fast-to-market projects.
