Pulse H1102NLT 10/100BASE-TX Ethernet Isolation Transformer, SMT

The H1102NLT is an Ethernet transformer from Pulse Electronics designed for 10/100BASE-TX Ethernet communication interfaces. It provides signal coupling, impedance matching, and electrical isolation in network interface circuits.

This single-port device integrates transmit and receive transformer channels, each with a 1:1 turns ratio. It features a minimum isolation voltage of 1500Vrms, a minimum open-circuit inductance of 350µH, and an operating temperature range of 0°C to +70°C. The specified frequency range extends from 100kHz to 100MHz, supporting signal transmission and isolation requirements in Ethernet applications.

The H1102NLT uses a surface-mount technology (SMT) construction, making it suitable for compact PCB layouts and automated assembly processes. Typical applications include Ethernet switches, routers, network interface circuits, and other wired communication equipment using 10/100BASE-TX connectivity. This model is rated as a non-PoE version, so system power requirements should be verified during component selection.

Before purchasing or integrating the device, consult the official Pulse Electronics datasheet to confirm pin assignments, isolation requirements, electrical characteristics, and PCB land patterns for compatibility with the target Ethernet PHY and interface circuitry.
