The interconnect system is designed for PCB mezzanine applications in enterprise networking towers and telecomms hubs and servers, in addition to industrial controllers and medical and military high data-rate scanning equipment. The mezzanine interconnect system has a patent-pending triad wafer configuration that isolates each differential pair for optimal performance and customisation. The honeycomb construction of the mezzanine interconnect housing routes each triad to minimise crosstalk and effectively route out of the PCB in one or two layers, claims the company. The tombstone structures located in the connector housing protect the mating interface and flexible contacts to help prevent damage to the terminals, says the company.  Featuring a density of 82 differential pairs per square inch, the interconnect system layout can be customised with high-speed differential pairs, high-speed single ended traces, low-speed single ended lines and power contacts, claims the company. The interconnect system is available with 85 and 100Ω impedance and mated stack height range of 12 to 40mm. The mezzanine interconnect system deploys the company's patented solder charge technology as an attachment method for PCB termination. The mechanical SMT process simplifies designs and facilitates strong solder joints in volume manufacturing by eliminating the need for thermal attachment and complex forms in the solder tail, claims the company. The plug assembly has a 2.8mm pitch between differential pairs. The receptacle assembly pin includes polarisation and keying features. The ground pin has two SMT attachment points, with four solder charge joints per triad and the PCB footprint does not change when mixing and matching the different differential pair, high-speed single ended and power triads within the housing. The orientation of the plug and receptacle provides a mirrored configuration with a dividing line of back-to-back shields. The resulting mirror line bisects the triad pair to facilitate PCB routing and RX and TX pin-out management for optimal signal integrity and mechanical stability.Mon, 04 Jun 2012 00:00:00 +0200http://www.epn-online.com/page/new189014/400ma-synchronous-dc-dc-converter-with-current-limiter-to-minimise-emc-emissions-and-radiated-noise.htmlnew189014Torex Semiconductor has announced two series of synchronous DC/DC converter ICs to its micro DC/DC family. The converter ICs are embedded within a shielded thin-film power inductor. With an integrated shielded inductor, the converter ICs are designed to minimise EMC emissions and radiated noise, claims the company. They also deliver a stable output with a peak-to-peak ripple of less than 10mV, and are suitable for RF applications. The converter ICs can deliver output currents up to 400mA and use a 1.2MHz switching frequency to minimise losses. The XCL201 converter ICs offers PWM control and the XCL202 converter ICs applies automatic PWM and pulse-frequency modulation switching control. All the converter ICs measure 2.5x2x1mm and needs two capacitors connected externally to generate a stable power supply. The operating voltage range is from 2 to 6V and the output voltage is internally set in a range from 0.8 to 4V in increments of 0.05V.  The converter ICs include a 0.25ms high-speed soft-start for quick turn-on, a chip enable pin to turn the IC on and off and a CL discharge function to quickly discharge the output capacitor when the IC is turned off. They also have a built-in under voltage lock out circuit whose threshold is 1.4V. The converter ICs stop operating when the input voltage decreases below this threshold, and resume normal operation when the input voltage rises above this threshold. In addition, they have a current limiter that not only stops the IC when the output current is too high, but also permits the IC to automatically resume normal operation as soon as the over-current condition disappears, claims the company.Mon, 04 Jun 2012 00:00:00 +0200http://www.epn-online.com/page/new189013/metal-film-axial-leaded-resistors-for-precision-controls-and-instrumentation.htmlnew189013Stackpole has expanded the RNF series of metal film axial leaded resistors to support tolerances of ±0.05% and temperature coefficient values of 10ppm.

They are suitable for medical equipment, instrumentation, military applications, servicing, upgrading or expanding pre-RoHS equipment. The relays have two change-over switches with a common open time. They are also used in data acquisition systems using the flying capacitor technique. This gives good isolation between the source and the device measuring it, claims the company.Fri, 01 Jun 2012 00:00:00 +0200http://www.epn-online.com/page/new188921/socket-and-header-strips-for-connecting-discrete-wires-and-mating-components.htmlnew188921Mill-Max has expanded its line of wire termination interconnects with four socket and header strips rated at 4.5A per contact. The connectors have pins and receptacles with soldercups that can accept up to 20 AWG stranded and 18 AWG solid wires. They are suitable to make connections between discrete wires or cables and mating components such as PCBs or other cable assemblies. The 800-XX-0XX-10-007000 and 802-XX-0XX-10-007000 are single and double row male header strips, respectively. The 801-XX-0XX-10-007000 and 803-XX-0XX-10-007000 are single and double row female socket strips, respectively.  The soldercup connectors are suitable for wire termination applications where direct wire connections are required. They eliminate the difficulties of soldering wires directly to boards and the headers and sockets form mating pairs for easy configuration of interconnects, claims the company. Uniform orientation of the soldercups makes it to solder the cable or discrete wires to the pins by eliminating the need to manipulate the wires or the connector to solder each wire, claims the company. The wires are securely soldered in the cups to provide an interface for discreet wire-to-board, cable-to-board or cable-to-cable applications. The brass pins and receptacle shells are high speed machined to precision tolerances. Each receptacle is fitted with the company's 47 stamped beryllium copper contact, which accepts 0.63 to 0.94mm diameter leads and 0.63mm square leads. The male headers have sturdy 0.76mm diameter pluggable pin tails for mating with the corresponding soldercup socket. Standard plating options are tin or gold. All connectors are on 2.54mm spacing and have high temperature polycyclohexylene dimethylene terephthalate insulators, suitable for RoHS soldering profiles. They are available from two to 64 positions single row and four to 64 positions double row.Thu, 31 May 2012 00:00:00 +0200http://www.epn-online.com/page/new188922/850w-12v-front-end-power-modules-for-networking-and-storage-applications.htmlnew188922Tectrol has introduced the TFE-850 series of hot-swap power modules with 12V output in a 1U horizontal and 2U vertical packages.
