Würth WE-FSFS Flexible Sintered Ferrite Sheet

Product Description

Würth Elektronik eiSos Flexible Sintered Ferrite Sheet (WE-FSFS) is a product designed for high performance magnetic flux redirection.

Magnetic Field Interferences are increasing in electronic devices due to a number of factors including reduced separation distances of PCB’s, Integrated Circuits and many other sensitive components. In addition to this the extended use of magnetically coupled communication technologies (Qi-WPC, NFC, RFID, PMA, A4WP, WCT…) leads to more complex layout and proximity considerations.

With Ferrite materials it is possible to manage and predict magnetic flux flow and thereby improve efficiency of power transfers, increase distances of near field communications and of course avoid additional unwanted coupling effects which could lead to losses or noise.

The correct management of the magnetic flux improves the energy and data transfer in inductive coupled systems (NFC, RFID, Wireless Power, etc.), achieving a higher efficiency and communication range.
Size and weight are critical parameters in today’s electronic devices. In the latest generation of ferrite compositions used in WE-FSFS, optimal results are achieved with minimal thickness.

Thanks to its structure WE-FSFS, despite its thickness, is resistant enough to support manipulation during transport, storage and assembly. The ferrite layer is cut by laser in 2 mm x 2 mm size squares, protected on one side by the PET layer and on the other by the double-sided adhesive layer.
This structure provides enough flexibility to stand repeated bending without a decrease on the electromagnetic performance of the product.

Bending tests have been performed by Würth Elektronik eiSos in order to guarantee the electromagnetic properties of WE-FSFS. A 10 cm bending radius deformation is applied and maintained during 30 sec. The cycle is repeated 20 times. After the test the electromagnetic properties of the specimens are measured and proved to be inside the specifications.

Thanks to its high μ’, when WE-FSFS is attached to a planar coil there is an increase of the inductance without a Q decrease, a similar effect to inserting a ferrite core into a traditional solenoid coil.
The combination of high performance and low thickness makes Würth Elektronik eiSos WE-FSFS flexible sintered ferrite sheets an indispensable partner for modern electronic devices.

PET protective layer

High surface resistivity and adhesive strength to protect the ferrite layer.

Pre-cut Sintered Ferrite Layer

This is the core of the product. Its magnetic properties concentrate and control the external magnetic fields.

Adhesive layer

High adhesive strength to protect the ferrite and to apply the product.
