What’s New Efficient, long life PoL


die. The DMS3014SSS and DMS3015SSS devices are said to improve the efficiency and lower the operating temperature of fast switching PoL converters in high volume computing, telecomand industrial applications.


With typical RDS(ON) ratings of 10mΩ and


Diodes Incorporated has introduced the first products fromits proprietary Diofet process thatmonolithically integrates a powerMosfet and anti-parallel Schottky diode into a single


8.5mΩ respectively at VGS of 10V, these devices minimise the conduction losses traditionally associated with low side Mosfets. Also, the Schottky diode forward voltage is said to be 25 per cent lower than comparableMosfet/Schottky solutions and

Available from CodeMercenaries, the new JoyWarrior24F14 claims to set a new price/performance benchmark for USB based acceleration sensors. At just 19 Euros per unit, the JW24F14-MOD offers resolutions down to 125µg in applications such as acceleration, tilt and low frequency vibration sensing, as well as for human input applications.


Modules are based on aMEMS sensor andmeasure with 14-bit resolution


delivering 125 results per second. Connection via USB allows use with any computermodel. Since JoyWarrior24F14 works as a joystick, accessing the data can be done via the operating systems joystick API without installing any specific drivers.


Software forMacOS X andWindows


contains a configuration tool to set the sensor parameters, a tilt anglemeasuring sample program, a calibration tool and a simple data recorder.

All you need for EMI protection


Kemtron provides a range of RFI/EMI shielding gaskets and components including highly conductive elastomers. These consist of silicone and fluoro silicones loaded with conductive particles such as silver plated copper, silver plated aluminium and nickel coated graphite. Elastomers can be extruded in various gasket profiles, moulded as components or sheet for die cutting.


Knitted wire mesh gasket strip is available in either monel, tin


AEG Power Solutions has introduced an extended warranty for its UPS and power protection solutions. The standard ex-factory two-year warranty can be upgraded to three-years.


AEG Power Solutions’ EMEA channel development director, Gary


Browning, said: “We believe we are the only UPS supplier to offer a three year warranty on both the chassis and batteries across such a full range of UPS up to 24kVA.


“The three-year warranty will be available through all of our channel


partners and it is a clear indication of the confidence we have in the quality and reliability of our compact UPS products. It is a unique proposition and assures our customers of not only long termpower continuity but also total product support.”

plated copper clad steel, stainless steel or aluminium. It is ideal in applications where low frequencies in the magnetic field are a problem and can be knitted to any diameter from one to 25mm as a solid mesh or over any type of sponge rubber cord or tube. Rectangular sections are available and sponge or solid rubber with a self adhesive backing can be bonded along the length of the mesh to form an environmental seal and or act as an assembly aid. Custom gaskets are available.


EMI shielded honeycomb vent panels in aluminium or steel help


maintain air flow into an enclosure while ensuring EMC integrity. The standard honeycomb vent panel is constructed from two layers of aluminium honeycomb set at 90 deg to each other and set in an extruded aluminium frame. Kemtron can also offer single layer styles, where lower levels of shielding performance versus reduced thickness are required.


48 per cent lower than the intrinsic body diode of a typicalMosfet, thus minimising switching losses and improving efficiency.


In benchmark tests, the Diofets operate


five per cent cooler than competing solutions. As every 10°C reduction in junction temperature doubles lifetime reliability the lower operating temperature significantly increases the PoL reliability.
