P-Duke has introduced medical grade PSUs that deliver 150W convection cooled, 180W fan cooled, and boost to 220W for 5s. The MAD180 series has 2xMOPP insulation and leakage current <100µA. “Being certified with EIC/EN/ANSI 60601-1 makes this supply suitable for any safety demanding type BF medical application,” said Luso, with is representing P-Duke in the UK. “It comes in 2 x ...

Miniature micro-layer (MML) film capacitors offer energy density of 400j/dm3 for weight and size reductions compared to polypropylene or polyester dielectrics. The capacitors developed by Exxelia are available from New Yorker Electronics. They also have an increased operating temperature up to 140°C and transient voltage protection. Capacitance ranges from 1μF – 1000μF and voltages from 50V – 1,000V. Operating temperature ...

Two medically approved open frame ac-dc converters, the LOF450 and LOF550, have been added to the Mornsun LOF series of medical and industry standard power supplies, available from Relec Electronics. The LOF series consists of low cost, reliable ac-dc converters which meet the latest regulatory standards. They are characterised by thermal design excellence and very short lead times, says the ...

Joe Sawicki , executive vice president, IC EDA at Siemens, challenged the mutterings that Moore’s law has run its course, and said the semiconductor industry was blighted with pessimism. At this year’s DAC (Design Automation Conference) he set about looking at the figures in a new light. “There have been morose expectations and miserable prognostics, for like 20 years,” he reasoned, ...

Design demands include a decrease in device size, cost and power consumption, while improving accuracy, sensitivity and reliability, observes Bill Walsh of Digi-Key Electronics. Of the four common types of temperature sensors – thermocouples, resistance temperature devices, thermistors and temperature sensor ICs – temperature sensor ICs are a good option for contact-based medical and healthcare designs. Principally, they do not ...

Hot on the heels of CUI, Trumpower has introduced a brick-style 300W ac-dc adapter built around GaN transistors. This time for medical users. TGM300 series power adapters are Class II for IEC 60601-1-11 home healthcare needs. “The GaN FET line achieves a power density greater than 9W/in3 and has a withstand voltage of 4,000Vac from input-output – 2xMOPP – and ...

The modular and configurable power supplies are designed for integration into mission-critical systems. Among the range available for fast delivery from Farnell are the UltiMod series of UX4 and UX6 AC-DC modular power supplies. They have up to 91% efficiency and low acoustic noise. The UX4 delivers up to 600W and can be populated with up to four power modules. The ...

Imec is co-developing with Swiss medtech specialist NeuroGyn an implantable device for peripheral nerve stimulation. NeuroGyn specialises in neurostimulaton and surgical solutions for pelvic nerve disorders. Leveraging Imec’s expertise in ultra-low power wireless communication and powering, the new implant aims at prolonging the lifetime of the device while lowering its cost, making it suitable at the point of need. Clinical ...

For some medical applications, the reliability of components is vital. Shiraz Vakharia of Knowles highlights some of the application-specific decisions medical device designers need to make. In the medical industry, highly reliable electronic components are necessary for a variety of devices – ranging from systems that diagnose, such as magnetic resonance imaging (MRI) machines, to implantable devices that treat patients, such ...

Review Display Systems (RDS) has introduced a 13.3in TFT display module for industrial use. Made by Tianma, the P1330FHF1MA00 is an HD display 1,920 x 1,080 pixels, 16:9 aspect ratio) with in-plane switching. “Tianma P-series display modules have been designed and developed to deliver exceptional optical performance and meet the requirements of the industrial and medical display markets and applications ...
