BGA Socket
Posted in Electronics & Computers, Electronics, Products, MDB on Friday, 01 July 2011
Ironwood Electronics (Burnsville, MN) offers a BGA socket for 1.118 mm pitch, 729 pin BGA IC’s. The SG-BGA-6345 socket is designed for 31 × 31 mm package size and operates at bandwidths up to 8 GHz with less than 1 dB of insertion loss. They are designed to dissipate up to several watts without extra heat sinking and can handle up to 100 watts with custom heat sink. The contact resistance is typically 20 milliohms per pin. The socket connects all pins with 8 GHz bandwidth on all connections. It is mounted on the target PCB with no soldering, and is constructed with shoulder screw and swivel lid which incorporates a quick insertion method so that ICs can be changed out quickly. The temperature range is -35 °C to 100 °C. The pin self inductance is 0.15 nH and mutual inductance is 0.025 nH. Capacitance to ground is 0.01 pF. Current capacity is 2 amps per pin.

External Medical Power Supplies
Posted in Electronics & Computers, Electronics, Products, MDB on Friday, 01 July 2011
XP Power (Sunnyvale, CA) has introduced the AHM series of external AC-DC power supplies aimed at medical and IT applications. The series comprises 5 single-output ranges of 85, 100, 150, 180, or 250 Watt output, and provides the popular nominal outputs from +12 to +48 VDC. All units are convection cooled, removing the need for any internal forced air flow, which is important for healthcare equipment located close to a patient.

LED Light Engine Platform
Posted in Electronics & Computers, Electronics, Photonics, Products, MDB on Friday, 01 July 2011
SCHOTT (Southbridge, MA) has introduced the 2nd generation of LEDgine™ LED light engine platform that now offers twice as much light as before. It was developed for more efficient coupling of LED light into fiber optic bundles, and illuminates active diameters from 3.0 to 6.0 mm. The small diameter is suitable for medical applications. The module includes an integrated fan that ensures optimum cooling for a long lifetime. The light engine is made up of white High Brightness LEDs, which are focused onto the input of the light guide by specially developed focusing optics (patent pending). The separate control electronics have been optimized to lower energy consumption and enable portability when used with rechargeable batteries. It monitors LEDs on the circuit board for over-temperature to ensure that the system remains functional for a long time. The external triggering option can be utilized to make fast movements visible. The light intensity of the LEDs can be continuously dimmed between 0 and 100%. For applications that require the use of an additional filter to cut off a particular wavelength (i.e. for ophthalmic applications), a light guide adapter with integrated filter slider can be mounted onto the optics module.

Surface Mount Chips
Posted in Electronics & Computers, Electronics, Products, MDB on Friday, 01 July 2011
Stackpole Electronics (Raleigh, NC) offers the RPC Series of surface mount chips that offer pulse withstanding in a 5% tolerance part. It is completely untrimmed, which allows the entire width of the resistance element to dissipate the pulse power without any current crowding. The thick film chip resistors are suitable for applications requiring low cost high pulse handling capability including many types of low to medium power supplies, medical applications, and imaging systems. They are available in tape and
reel packaging in quantities that vary depending on size.

Triple Row Connectors
Posted in Electronics & Computers, Electronics, Products, MDB on Friday, 01 July 2011
Mill-Max (Oyster Bay, NY) offers 804 and 805 Series interconnects, suitable for high pin count I/O and board-to-board applications. The triple row pin field allows for signal connections to be more densely packaged. Placing and soldering one connector rather than three SIP sockets or a single and double row combination increases assembly
efficiency and improves positional accuracy. The triple row package, on a .100" (2.54 mm) grid, is available from 9 to 96 position configurations. The connectors are RoHS compliant and feature high temperature thermoplastic insulators compatible with lead-free soldering temperature requirements.

COTS Filters
Posted in Electronics & Computers, Electronics, Products, MDB on Friday, 01 July 2011
LCR Electronics (Norristown, PA) offers a line of single phase COTS filters that operates over an extended temperature range of -40 °C to 85 °C (-40 °F to 185 °F). The RoHS-compliant Single Stage F9100 Filters and Double Stage F9200 Filters are suitable for high ambient environments or in applications with limited temperature rise requirements as found in the military, industrial, and medical applications. The 115/250 VA 50/60 Hz filters are available with rated current from 5 A to 35 A, in both general purpose and low leakage current versions. High potential voltage for both series is 1,450 VDC line-to-line and 2,250 VDC line-to-ground.
