August 2, 2007[Component View] Current Transducer Runs On Single 5-V Supply
The HMS current transducer from LEM S.A. integrates a primary conductor into a surface-mount package measuring only 0.630 by 0.531 by 0.472 in. The device operates from a single 5-V supply. Four standard versions cover nominal ac, dc, pulsed, and mixed isolated current measurement of 5, 10, 15, or 20 A rms, up to 50 kHz, with a measuring span of up to ±3 times IPN. A version for through-hole mounting will be available shortly. The internal...
July 5, 2007[Component View] 1/8-Brick Module Boasts High Power Density
With a 40-A output at 3.3 V, the PKB4110C 1/8-brick dc-dc converter from Ericsson Power Modules delivers up to 60% more power than previously released modules of similar size. The converter comes in two versions—through-hole and surface-mount. A third option features a broader baseplate to accommodate higher operating temperatures in applications where airflow is restricted. The use of a secondary digital monitoring circuit allows control of an infinite ...
June 7, 2007[Component View] Flex Circuits Offer High-Density Capability
Stratos Optical Technologies now offers increased packaging density as a custom manufacturing option for its optical flex circuit products (see figure). The new optical flex circuit design is called the Shuffle because fiber channels can criss-cross each other for optimum routing paths. The...

March 1, 2007[Component View] Small Switching Supplies Approved For Medical Apps
The ASM Global Performance series of ultra-miniature open-frame switching power supplies features 10 versions with single outputs of 3.3 to 24 V dc and a power range of 10 to 15 W (see the figure). All of the models accept inputs of 90 to 264 V ac. The supplies, which incorporate corner...
February 15, 2007[Component View] 1-By-16 PLED Drops In To Replace LCD Units
The OSD1601-D is a one-line by 16-character polymetric LED (PLED) display module from OSD Displays. The module's high-contrast yellow-green characters measure 4.51 by 8.6 mm, creating a display active area of 84.31 by 8.6 mm. The display's total overall mechanical dimension is 122 by 33 by 8.9 mm deep. Compared to negative-mode LCD modules, the OSD1601-D saves significant power. The typical current consumption with 25% pixel use and a full screen of characters at 40 nits is...
