Embedded magnetics eliminate termination components

Embedded magnetics eliminate termination components

Tyco Electronics unveiled three new embedded magnetic product offerings from its recently acquired PlanarMag product technology, to fully automate traditional hand-wound coiling processes. The new PlanarMag product technology capitalizes on three innovations to dramatically improve the design and manufacture of electromagnetic components: the use of proprietary material to embed highly sensitive magnetic ferrites into standard PCBs, the use of a 3D-electromagnetic simulator with unique design techniques to create patented proprietary winding structures, and standard PCB processes to manufacture boards containing hundreds to thousands of parts at once.

TE’s initial roll out of PlanarMag products includes two discrete Ethernet components and a 1G Mag45 ICM (part number 1840771-2) with PlanarMag product technology embedded magnetics. The discrete components are 1G BASE-T media filters (part number 2048107-1) and 10/100 BASE-T media filters (part number 2048108-1). Key product features common to the entire product offering include a single-port configuration and a media filter and isolation transformer.

The PlanarMag products reduce or completely eliminate termination components because of their precision center tap and transformer symmetry.  This consistency and repeatability improves performance and can help facilitate FCC class B compliance. The 10/100/1G BASE-T media filters have a 24-pin BGA configuration and the 10/100 BASE-T media filters have 12-pin castellation I/O’s (an industry standard pin-to-pin design) for customers to easily qualify and ramp production in existing products using gull-wing discrete.

All products are RoHS-compliant per JEDEC J-STD, meet the IEEE 802.3 specification and can help facilitate FCC Class B qualifications. Product applications include low-port density switches and routers, low-profile notebooks/netbooks, desktop computers, IP routers, cable modems, set top boxes, TV/DVR, IP phones, IP cameras, video game consoles and more.
