Receiver Coil used in BQ51013EVM-725
I am looking for the suitability of wireless charging in our product. I read through the BQ51013EVM-725 Evaluation Module document. The BOM refers to the receiver coil P/N IWAS-4832FF-50 manufacturer as Vishay. I am not able to locate the above part in the Web. Based on the size and the dimensions of the receiver coil, we have to decide the siutablity of the wireless charger in our product. Please share the datasheet and availability of the coil.
Thanks and regards,
Hello M. Ramasamy
Contact information on the Receiver Coil from Vishay can be found in the FAQ section. I have copied it below.

what about the very thin ferrite slab which is a part in the receiver as attached? who is produce this magnatic component?
The shield is part of the receiver coil, it is provided as a complete assembly. The coil used on the EVM (your photo) is manufactured by Vishay and P/N is IWAS-483FF-50, see the EVM user’s guide (SLVU447) page 6.
Also manufacture contact info can be found in the FAQ post on the forum.
I am working on low power application (around 100-200mAh on receiver side). For that i need small ferrite core and coil. The size should be around 10mmX20mm. Remaining 10mmX20mm use it for receiver PCB assembly.
Let me know whether i can get small size coil and core.
