Maximum output power rating for the CPPD line is 27 dBm, with an operating temp
The history of portable electronics is one of decreasing size, both for the devices themselves and the batteries to power them. A while back, I reported on the Quad A battery—specifically, Energizer’s push to make the Quad A more commercially available. The Quad A was commercially available (though not prevalent) since 1989. Similarly, the technology behind Energizer’s latest offering, the Zinc Air Prismatic Battery (or ZAP for short), has been around since 1991.
Built with TPMOV surge suppression technology, Ferraz Shawmut’s new Surge-Trap surge protective devices (SPDs) comply with the UL 1449 Third Edition standard. The units exhibit modular-style IP-20-grade “finger-safe” protection, and mounts on a DIN rail to safeguard critical electrical system components from transient overvoltage effects. The devices suit system voltages from 120 V to 600 V, and are MCOV rated from
Measuring up to 26.2’ (8 m), Gems Sensors & Controls' UCL-520 Series ultrasonic level sensors are suitable for non-contact fluid applications, such as industrial water treatment, wastewater management, and chemical storage. The two-wire ultrasonic transmitter offers a PVDF transducer, a 8” min. dead band, a 3” min. beam width, and a selectable display indicating levels in air gap or liquid height. The device is push button calibrated with
Using common wire gauges in cable lengths up to 10 meters, FCI’s DensiShield I/O links exhibit 10 Gb/s per channel differential performance. The differential performance can be achieved at 6 meters or less by utilizing 30 AWG cable, at 8 meters or less by utilizing 28 AWG cable, and at 10 meters or less by utilizing 26 AWG cable. The devices meet the 10GBase-CX4 Ethernet and Infiniband industry standards. The products accommodate
Bundling with a PICMG 1.0 Core2 Quad/Dual or Pentium 4 single board computer (SBC), Advantech’s IPPC-7158B 15” industrial panel PC exhibits a passive backplane with up to 12 ISA/PCI expansion slots. The unit consists of a XGA TFT LCD, a front-accessible design with water resistant cover; a flat-sealed front-panel, and an aluminum detachable side-open front panel (NEMA4/IP65 compliant). The model includes
Offering sizes of 12.70 mm², 15.88 mm², and 19.05 mm², EAO Switch’s Series 95 color-changing pushbuttons allow up to 2 (12.70 mm²) or 3 (15.88 mm² and 19.05 mm²) LEDs to be added. The 24-mm high (max.) devices have an N/O self-cleaning gold-plated switch element rated at up to 48 VDC/50 mA. The units are suitable for mounting on PCBs between 1.50 mm and 2.50 mm thick and can be snap-mounted to the PCB. The switches

This podcast is a discussion of MEMS and nanotechnology in the international marketplace, and is part of a series on disruptive technology done in conjunction with Hannover Fairs, and is intended to be a snapshot of the MEMS Nanotech facet.
Distributed power means different things to engineers. Some think of it only as the distribution of different DC voltages on a circuit board or in a rack of equipment. But good power-distribution engineering starts at the power company's connection to a building's wiring and goes all the way down to IC power inputs.
Using a buck topology, Supertex’s HV9919 SSLD uses a hysteretic control function to maintain its output current between a fixed minimum and maximum level at all times. The PWM controller performs in solid-state lighting applications, such as industrial, architectural, signage, or decorative lighting; indicator or emergency lighting; and as a general-purpose, constant-current source. The component offers programmable dimming frequency via
