PT61017PEL is a LAN 10/100 Base-Tx Ethernet transformer module designed for IEEE 802.3 compatible network applications. It features a turns ratio of 1CT:1CT (±5%), inductance of 350 µH minimum at 100 KHz, and insertion loss of -1.15 dB maximum across 0.3-100 MHz. The transformer provides excellent common mode rejection ranging from -40 dB at 30 MHz to -30 dB at 100 MHz, with crosstalk performance of -45 dB minimum from 1-60 MHz. With a hipot rating of 1500 VAC (PRI-SEC) and operating temperature range of 0°C to +70°C, this potted construction module is ideal for adapter, hub, and motherboard applications in LAN and Ethernet environments.
