DESCRIPTION

ALAN210001-3J61DT is a POE-10/100/1000 BASE-T single port SMD LAN transformer module designed for high-speed Ethernet applications with Power over Ethernet (POE) capability. The module features 1CT:1CT TX and RX transformers with high-performance magnetics for EMI suppression and common mode noise rejection, supporting data speeds up to 1 Gbps and power delivery up to 30 watts at 57V continuous with a maximum current capability of 600 mA. Key electrical characteristics include an inductance of 350 µH (minimum), leakage inductance of 0.5 µH (maximum), interwinding capacitance of 35 pF (maximum), and DC resistance of 1.2 O (primary) and 1.0 O (secondary), with a high-pot rating of 1500 Vrms. The device operates over an extended temperature range of -40°C to +125°C and meets IEEE 802.3at standards, making it ideal for fast and gigabit Ethernet applications in hubs, servers, switches, routers, access points, IP cameras, surveillance systems, industrial computers, and networking equipment.
