Inductive Components - Wireless Charging Coils

Wireless charging technology can be inefficient due to poor communication between devices or a buildup and eventual overload of energy within a device's internal battery. Our engineers understand this constant struggle and have developed extremely effective, reliable wireless charging coils using carefully selected ferrite materials.

Their high Q Factor creates maximum wireless power charging efficiency while minimizing EMI. They use wireless power consortium (WPC) ferrite material and the coil module design is WPC Qi specification compliant. The power transmitter design provides up to 15 W, and even higher power designs are available upon request. 

Flexible, reliable wireless charging solutions

Laird Steward develops Qi charging coil solutions that maximize charging efficiency within the strict size constraints of electronics applications. In this way, Laird Steward wireless charging coils support the advancement of innovative designs in automotive electronics, 5G devices, wearables, medical devices and more.

Further, Laird Steward’s ferrite sheet materials provide design engineers maximum flexibility as they seek to suppress EMI and manage energy and data transfer. Engineers can also target stray EMI precisely with Laird Steward’s ferrite plate materials.

Laird Steward uses advanced simulations to pinpoint the sources of signal interference in wireless charging applications and then target noisy areas with shielding. Leveraging high-quality materials and custom automation and product development capabilities, Laird Steward delivers high-performance wireless charging solutions that are compliant with the WPC Qi specification.

What’s more, Laird Steward can integrate multifunctional materials into a single design to achieve high quality, reliability and performance. That is why Laird Steward wireless charging coils are automotive standard AECQ-200 (reliability specification) approved and widely selected by strategic automotive partners.
