San Diego, Calif. Pulse, a Technitrol Company, claims to offer the industry's smallest gigabit quad- and dual-port discrete isolation transformer modules. These gigabit modules are 50 percent smaller than currently available modules, so printed-circuit-board (PCB) designers can fit more components on the circuit board or reduce the size of the circuit board.
The surface-mount transformer modules use ball grid array (BGA) technology, and are solder bumped and tested for easy SMT attachment to the PCB for computer, telecommunications, and networking applications such as Power over Ethernet (PoE), small office home office (SOHO), hubs, routers, and switches.
The Quattro H5400NL and H5401NL quad-port modules measure 29-mm long x 17.5-mm wide x 11-mm high, while the Dos H5200NL and H5201NL dual-port fit into a 14.7-mm long x 17.5-mm wide x 11-mm high footprint. The quad-port fits behind a 2x2 RJ45 connector, which makes board layout easier and more compact, said the company.
These modules are guaranteed to meet co-planarity of 0.005 inches (5 mil). The solder bump grid array interconnect is said to enable high input/output (I/O) density; fits in a small footprint, and can be applied with SMT assembly.
The Quattro quad-port and Dos dual-port modules provide electrical circuit isolation to safeguard against electrical shock and reduce noise and electromagnetic interference to maintain signal integrity. These RoHS and IEEE 802.3 compliant parts have also been tested and validated by top tier gigabit integrated circuit vendors, according to the company.
The Quattro H5400NL and H5401NL quad-port and Dos H5200NL and H5201NL dual-port discrete isolation transformer modules can be used with Pulse's unfiltered connectors, part numbers E5908-57A132-L and E5908-25A1J5-L, respectively.
Pricing: The Quattro and Dos transformer modules are available in trays and are priced at $2.19 per port for 10,000 units. Price varies depending on order configuration and destination.
