Wraparound resistors increase density in 0805 case size
PCIM Europe 2017: Vishay Intertechnology has introduced a series of thick film surface-mount wraparound chip resistors with high power ratings of 0.33 W in the compact 0805 case size.
Laser welding capabilities for manufacturing EV battery packs
A range of resistance and laser welding capabilities for manufacturing battery packs for hybrid and electric vehicles has been announced by AMADA MIYACHI EUROPE. The company helps customers select the right tab to terminal connection welding system for batteries used in power train electrification of cars, trucks, buses and motorbikes. Also available are systems for welding battery packs used in cordless power tools and energy storage, inclu...
Surface mount PPTC devices protect charging cables from overheating
PCIM Europe 2017: Compact, and with low resistance, the PolySwitch LoRho series of surface mount PPTCs offer higher voltage, over-current/over-temperature protection, and resettability, says Littelfuse.
Surface mount isolated current transducers have an integrated current conductor
PCIM Europe 2017: LEM introduces the GO series, expanding its miniature, IC transducers range for AC and DC isolated current measurement up to 300kHz.
Compact AC-DC modules pack in the power
A family of AC-DC modules that provide significantly more power in an ultra-compact 2x4 inch (50.8 x 101.6mm) package than comparable solutions available in the market are available at Luso Electronics. The XL270 Series from Qualstar constitutes single output combinations of 12V, 24V, 30V, 48V and 56V models, but other voltage options in this range are easily attainable.
Electroplating delivers high-power batteries
The process that makes gold-plated jewelry or chrome car accents is now making powerful lithium-ion batteries. Researchers at the University of Illinois, Xerion Advanced Battery Corporation and Nanjing University in China developed a method for electroplating lithium-ion battery cathodes, yielding high-quality, high-performance battery materials that could also open the door to flexible and solid-state batteries.
Diodes deliver superior efficiency and state-of-the-art robustness
A full range of 2A-40A 1200V silicon-carbide (SiC) JBS (Junction Barrier Schottky) diodes from STMicroelectronics enables a wider range of applications to benefit from the high switching efficiency, fast recovery, and consistent temperature characteristics of SiC technology.
Differential amplifier delivers up to +50dBm OIP3
Analog Devices, which recently acquired Linear Technology, has announced the LTC6432-15, a wideband fully differential amplifier with 15dB gain, offering linearity of up to +50.3dBm OIP3 (output third-order intercept), very high OP1dB (output 1dB compression point) of +22.7dBm, and 3.2dB noise figure at 150MHz. In addition to its outstanding signal-to-noise at high frequencies, it maintains its dynamic range performance even at lower frequencies.
Power supplies meet medical safety approvals
A new range of products from power supply manufacturer Cosel is in stock at RS Components (RS). With rapidly growing sales in Europe the brand is well-known in Japan and the US for manufacturing reliable and high-quality power supplies, including ultra-small AC/DC switching supplies and DC/DC converters.
The power within the food chain
We take for granted what an important role electricity plays in the food chain; from powering microwaves to keeping fridge-freezers running. Yet even before products reach the hands of consumers, a constant supply of reliable power is required to ensure that food is produced safely and properly. Steve Hughes, Managing Director of power quality specialist REO UK, explains how electrical engineers can protect food manufacturing plants fro...
