Vinyl plugs

01 March, 2006 | Supplied by: StockCap

StockCap has released a range of Plus-Plugs that are made of flexible vinyl incorporating a 360° pull-tab so that they are easier to remove and more adaptable than traditional rigid poly plugs.

PCB testing

01 March, 2006 | Supplied by: http://www.parameters.com.au/

By combining electronic and mechanical testing through mounting the board under test in a cantilevered or two-support beam position and subjecting it to an oscillating force, important reliability information can be gained and incipient failure modes; eg, track breakage, SMD and pin joint failures revealed.

Power transformers

01 March, 2006 | Supplied by: http://www.siemens.com.au/

With its E high-power series, Epcos has introduced a family of transformers that can handle extremely high power densities while taking up less space. The EHP 16, for example, can transfer 25 W, twice that of the commonly used EF16 transformer with the same footprint. The latest transformer series comprises four versions: EHP 16 and EHP 19 as SMDs designed for 25 and 35 W, while the EHP5.0 and EHP 26 are leaded components designed to handle 50 and 100 W. The components' space requirements range from 17 x 23.3 mm to 27 x 27.5 mm. The pre-tinned core can be soldered directly to the circuit board, which ensures good heat transfer and improved cooling.

Broadband access

01 March, 2006 | Supplied by: http://www.symbol.com/australia/
