Flexible AMOLED shipments to overtake rigid in 2020
Feb
Shipments of flexible AMOLED panels are expected to reach 335.7 million units by 2020, topping those of rigid AMOLED panels at 315.9 million units.
Flexible AMOLED panels are predicted to make up 52% of total AMOLED panel shipments, up from 38.9% in 2018.…
44V 5A stepper motor chip offers 128 micro-step mode for quiet operation
Feb
TB67S128FTG, as it is to be known, also supports full, half, quarter, 1/8, 1/16, 1/32 and 1/64 step operation – micro-stepping is by PWM, using sine-wave derived on-off ratios – output chopping frequency can be adjusted by external resistance and capacitor.
Power dissipation is minimised using low-output resistance (0.25Ω) p and n-channel mosfet output brid…
IR LED with 7mm spot diameter
Feb
With up to 10mW total radiated power at the maximum drive current of 100mA, and 2.25° angle of half intensity, the OP207CL couples optical flux extremely efficiently onto the receiving photo-sensor to ensure clearly detectable on/off transitions.
The integrated collimating lens creates a tight beam profile for use with accuracy-dependent devices such as radial o…
Cree upgrades XLamp line
Feb
Connected lighting systems use information from occupancy sensors and other sources to continuously react to the target environment, dimming or switching off unneeded lights to conserve energy.
On average, a connected lighting system will dim or switch off lights up to 10 times more often than with a standard lighting system.…
Challenger Solutions gets AS9100 approval
Feb
“Everyone gets ISO 9001,” Challenger business development manager Richard Hancock told Electronics Weekly. “AS9100 approval now allows us know to deal direct with aerospace OEM’s”
The firm is mid-sized, with 85 staff. “We are big enough to cope but small enough to care,” claimed Hancock. “We have resources to handle one-off prototypes to full scal…
Schurter hones tough switch line with better lighting
Feb
The switches of the MSM family retain the original 19, 22 or 30mm diameters, and stainless steel or aluminium housings, but have changed in two places, both involving the illumination:
Ring illumination is more even – “by cleverly selecting a new material that diffuses the light much more widely”, according to the firm. “The LEDs used for ring illuminatio…
Fujitsu triples output power of GaN HEMTs
Feb
Fujitsu has developed a crystal structure that increases both current and voltage in GaN HEMTs, effectively tripling the output power of transistors used for transmitters in the microwave band.
GaN HEMT technology can serve as a power amplifier for equipment such as weather radar. …
UK allocates £100m for independent GPS plan
Feb
The Continentals are threatening to ban the UK from using the military encrypted signals from the EU Galileo satellite constellation.
Richard Wimmer, Project Manager of the Aeolus satellite at Airbus in Stevenage, told the Sunday Telegraph : “Britain is still a very very key player in ESA (European Space Agency) which is a separate organisation to the European …
GloFo cans 7nm
Feb
Instead, the company will concentrate its resources on its 14/12nm Finfet process.
“GF is putting its 7nm FinFET program on hold indefinitely,” says the company. It is assumed that the 5nm and 3nm programmes are also scrapped.…
3D printable PEEK polymer for high-performance connectors
Feb
“PEEK is considered as one of the most powerful high-performance polymers due to its mechanical, thermal and chemical resistance. It is used as a replacement for steel, aluminium and other polymers,” said the firm. “In the environment of semiconductors and electronics industry, PEEK and carbon-fibre-reinforced PEEK can realise your designs for connectors, wa…
Emergency stop switches conform to UL, TUV, ATEX, CE, and CCC
Feb
By reversing the position of the spring, the contact’s relaxed state corresponds to its safety position (when contacts are open, the machine is at a standstill). The spring does not undergo any load once the plunger has been pressed down and as a result, risk of malfunction is significantly reduced, especially when the push-button has been damaged.
By using ‘…
Improved aerospace proximity sensors
Feb
Honeywell has over thirty years’ experience designing accurate and reliable aircraft proximity sensors for extreme environments, and its IHM Series reduces downtime and maintenance costs by obviating the need for unnecessary preventative maintenance and troubleshooting.
The IHM Series has a unique circuit that can detect any internal failure modes and display a…
Fast opto-coupler for automotive
Feb
TLX9309 is AEC-Q101 qualified and consists of a GaAlAs LED optically-coupled to a photo-diode backed by an amplifying transistor.
By separating the photo-diode and amplification transistor, said the firm, collector capacitance is reduced, cutting propagation delay – times are guaranteed to be between 0.1μs and 1.0μs, with the difference between high to low …
Chip controls up to seven USB-C ports, and Power Delivery
Feb
It is called HX3PD, and aimed at notebook and tablet docking stations, monitor docks and multi-function USB-C peripherals.
“USB-C docks have been complex to design, requiring two USB hubs to support internal and external connections, a dedicated controller for every USB-C port that supports USB PD charging, along with a USB billboard and USB-C bridge controller…
Led driver puts out 1.6A at up to 38V, from 5-38V
Feb
Buck-boost, buck and SEPIC topologies are also available from the same module, which comes in a high reliability (H-grade) version that guarantees operation from –40°C to 150°C. “The wide input voltage range and 150°C operation make this µModule LED driver ideal for automotive and industrial lighting applications,” claimed the firm.
Inside are: a dc-dc …
