PoE Discrete Magnetic Components

Pulse introduces the Star Magnetics series of single- and dual-port discrete magnetic, extended-temperature, Power-over-Ethernet (PoE) products. The single-port HX2260 and dual-port HX2305 operate between –40°C and
85°C PoE enables remote power feeding of 15 W to the remote terminal device, thereby providing both power and a Fast Ethernet 10/100 BaseT connection over the same Category 3/5 Ethernet cable. These are the first PoE-compatible discrete magnetic components available that also can operate at extreme temperatures; therefore, one component can be used in industrial Ethernet applications.

The cost-effective Star Magnetics components comply with the IEEE’s 802.3u Fast Ethernet and 802.3af PoE standards along with ANSI’s X3.263 standards, and meet IEEE 802.3 HiPot isolation requirements. They provide a 350 µH minimum open circuit inductance (OCL) with 8-mA bias applied. Applications include industrial Ethernet, motor drive controls, network interface cards (NICs), and Voice-over-Internet Protocol (VoIP) phones.
