Our charging coil arrays include both two and three coil devices, with inductances from 6.4µH to 12.5µH.

The batteries used in wireless devices like mobile phones, PDAs, headsets and laptops need frequent recharging from an electricity mains source. Replacing the traditional charging cable with a contactless charging arrangement would greatly increase these devices’ convenience and mobility – and this can be done through inductive coupling.

A wireless power array using inductive coupling can be built using PCB mounting coreless coils. These are flat, lightweight, and easy to manufacture.

Although these coreless PCB coils in general have a low coupling factor between the primary and secondary coil, high efﬁciency can be attained by using a high-frequency resonant circuit. Operating the circuit at high frequency makes the impedance of the coils large. Therefore, power will be transmitted using low currents and high voltage. Because of these low currents, heat generation by the ﬁne conductors of the PCB mounted wireless charging coil array stays within acceptable bounds.

Our products include Vishay’s wireless charging transmitter coils/shields which feature high permeability shielding and high saturation powdered iron that is not affected by permanent locating magnets.

Also available are products from Wurth Electronik’s WE-WPCC wireless power array range, which uses Litz wire and achieves the highest Q value on the market. The wireless power arrays cancel charging flux to avoid coupling into sensitive components or batteries.
