J3011G21DNLT Description

Short technical summary and product information.

The J3011G21DNLT from Pulse Electronics is a single-port surface-mount RJ45 connector with integrated magnetics. It is designed for 100 Base-TX Fast Ethernet applications and supports AutoMDIX. The connector features a 90° right-angle orientation with tab-up configuration. It includes green and yellow LED indicators for link/activity status. The shielded design provides EMI suppression, and the part includes a board guide, BST circuit, and EMI finger. Electrical specifications include a 1:1 turns ratio for both TX and RX, -1.0 dB maximum insertion loss, and return loss of -20 dB at 1-10 MHz, -16 dB at 30-60 MHz, and -12 dB at 60-100 MHz. Common mode rejection is -40 dB at 1-10 MHz, -35 dB at 30-60 MHz, and -30 dB at 60-100 MHz. Crosstalk is -30 dB at 1-10 MHz and -20 dB at 30-60 MHz. The connector provides 1500 Vrms isolation per IEEE 802.3. Operating temperature range is 0°C to 70°C, with an extended range of -40°C to 85°C noted in the datasheet. The component is RoHS compliant and MSL 1. Packaging is tape and reel (suffix T).
