Wireless Charging Coil Modules/ Ferrite Plates
Wireless charging technology efficiency is critical to the performance of the devices using it. In order to keep this under control, ferrite materials need to be carefully developed and selected.
This range from Laird is characterised by a high Q factor which creates maximum wireless power charging efficiency while minimising Electromagnetic interference (EMI). They use wireless power consortium (WPC) ferrite material and the coil module design is WPC Qi specification compliant. Standard power transmitter design provides up to 15 W and even higher power designs are available upon request.
Laird can integrate multifunctional materials into a single design to achieve high quality, reliability, and performance. That is why Laird wireless charging modules are automotive standard AECQ-200 (reliability specification) approved and widely selected by strategic automotive partners.
