7499410420 Description

Short technical summary and product information.

The Würth Elektronik 7499410420 is a single-port RJ45 connector with integrated magnetics, designed for 10/100 Base-T Ethernet applications. It features a through-hole mounting style with a right-angle orientation and a downward tab direction. The shielded housing provides EMI protection, and the connector includes green and yellow-green LED indicators for link/activity status.

 

Electrical specifications include an open-circuit inductance of 350 µH minimum at 100kHz/100mV with 8mA DC bias, a 1:1 turns ratio for both transmit and receive channels, and an insertion loss of -1.0 dB maximum from 1 to 100 MHz. Return loss meets -18 dB minimum at 1-30 MHz, -13.5 dB at 30-45 MHz, -12 dB at 45-60 MHz, and -10 dB at 60-80 MHz. Common mode rejection and crosstalk are both -30 dB minimum across the frequency range. The part is rated for a current capability of 600 mA and a hipot test voltage of 1500 Vrms.

 

The connector is built with a thermoplastic UL-94V0 housing, gold-plated contacts (30µ" over nickel underplating), and a nickel-plated copper alloy shield. The base material is ferrite, and the wire insulation is UEW rated for 155°C. Operating temperature range is -40°C to 85°C. The part is compliant with IEEE 802.3at for Power over Ethernet+ (PoE+) applications.
