Pulse announced the introduction of their new PulseJack Harmonica family of multiport RJ-45 connectors with integrated magnetics. These connectors cut assembly costs for manufacturers of high density hubs and switches by reducing the overall component count. Co-developed with the Communications Business Unit of Tyco Electronics (AMP), this two-tier, stacked line of 8-, 12-, and 16-port RJ-45 connectors integrate magnetics to provide the isolation and EMI suppression necessary for today's 10/100 Base-T computer and telecommunications networks. Designed from the ground up as one integrated module, PulseJack Harmonica connectors give switch manufacturers a cost-efficient, high-component-density solution while exceeding the IEEE 802.3 and ANSI X3.263 standards.
AMP's space-efficient stacked package allows shorter traces between the RJ-45 connectors and the LAN transceiver, improving both EMI emissions and electrical performance. The 2x4 8-port (part number J2042H3A), 2x6 12-port (part number J2045H3B), and 2x8 16-port (part number J2039H3C) connector modules feature Pulse's InterLock base construction that minimizes the stresses of human handling of sub-components such as coils, leads and interconnecting wires, resulting in higher quality and reliability.
Fully shielded, the multi-port PulseJack Harmonica connector meets or exceeds the 1500 Vrms isolation, IEEE 802.3, and ANSI X3.263 standards, including the rigorous 350μH minimum open circuit inductance with 8 mA bias.
