San Diego, Calif. Pulse, a Technitrol Company, has introduced a line of extended temperature integrated magnetic components for industrial Ethernet applications where components are exposed to extreme temperatures. These applications include servers, network interface cards, motor drive controls, switches and hubs in PC and SoHo markets, and Voice over Internet Protocol (VoIP) phones.
The Star Magnetics series of single-port (HX1260 and HX2260), dual-port (HX1305 and HX2305) and quad-port (HX1259) Fast Ethernet (10/100 BaseT) magnetic components operate between -40°C to 85°C. The components comply with the IEEE's 802.3i 10 BaseTX and 802.3u Fast Ethernet standards along with ANSI's X3.263 standards, and meet IEEE 802.3 1500 Vrms HiPot isolation requirements. They provide a 350 μH minimum open circuit inductance (OCL) with 8 mA bias applied.
The single-port HX2260 and dual-port HX2305 devices provide Power over Ethernet (PoE) capability that enables remote power feeding of 15 watts to the remote terminal device.
A key benefit of these components is providing a power feed and maintaining specs to the lower temperature, said Mark Jackson, senior product manager for Pulse's LAN division.
Jackson said most parts that work to 70°C will extend to 85°C. The difficulty is maintaining insertion loss, return loss, and open circuit requirements specified in IEEE 802.3 when the component is cooled down to -40°C, he said.
Available in tubes or tape-and-reel packaging, prices start at $1.03 per port in quantities of 10,000. Unit price may vary depending on configuration and shipping destination. Delivery is six to eight weeks.
Detailed technical specifications are available on datasheet H600.
