LPJ19911ADNL SMT RJ45 with integrated 10/100BASE-T magnetics, EMI spring finger, LED option, reflow compatible, -40–+85°C. Datasheet & cross-refs.
The LPJ19911ADNL is a low-profile, single-port SMT RJ45 connector with built-in 10/100BASE-T magnetics and LED indicators. It integrates common-mode choke and transformer windings (turn ratio 1CT:1CT) meeting typical Fast Ethernet isolation and coupling requirements, while the EMI spring finger shield tabs provide chassis grounding options to reduce radiated emissions. The connector is optimized for SMT reflow assembly with recommended IR reflow profile and is rated for operation from -40 °C to +85 °C, making it suitable for industrial, telecom and embedded networking applications where robust thermal performance and automated production are needed.
