Why you don't want open vias in or near PCB pads
The term ‘via’ probably comes from the Latin word meaning ‘road’. Therefore, open via would essentially mean ‘open road’. Open roads, in Oregon for example, sometimes run through open range ranch land. That means that cows have as much right to be on the road as do cars. If you don't want cows on your PC boards where the BGAs go, don't leave open vias in your BGA footprint. By Duane Benson, Chief Technology Ch...
Smart-antenna controller cuts board space
A new digital controller from STMicroelectronics, the STHVDAC-253C7, is for tunable capacitors such as ST’s STPTIC family, and shrinks the size, bill of materials (BoM), and power consumption of antenna-tuning circuits for stabilising smartphone RF performance. Using the STHVDAC-253C7 with STPTIC capacitors for impedance matching and frequency tuning almost completely eliminates the effects of environmental variations.
Capacitors voltage rating raised to 500V
The maximum voltage rating of the Vishay BCcomponents 500 PGP-ST series of aluminum screw-terminal capacitors has been extended to 500V while more than doubling its useful life to 5000 hours at +85°C. As polarised aluminium electrolytic capacitors with a non-solid electrolyte, 500 PGP-ST series devices are optimised for DC-Linking in power conversion electronics rated at 20kW and above — including large motor drives, UPS systems, and so...
Two regulators implement higher power output to accelerate operation
Two regulators by Alpha and Omega Semiconductor have high power output to meet the demands of next-generation microprocessors and SoCs, says the company.
Disc capacitors enhanced by higher voltages
The Vishay Cera-Mite 715CxxKT series of ceramic screw-mounting disc capacitors has been expanded with higher voltages to 50kVDC (34kVRMS). With low AC and DC coefficients and a negligible piezoelectric / electrostrictive effect, 715CxxKT series capacitors are specifically designed to function in circuits with high peak current and high repetition rates.

The release of the most advanced transmission speed sensor family members, complete with ASIL B certification has been announced by Allegro MicroSystems Europe.The A19520, A19530, and A19570 magnetic sensor ICs are the product of nearly 20 years of application-specific experience and technological advancement- including GMR and Hall effect technology- making them suitable for meeting the demanding requirements of today’s transmission applic...
Capacitive structure: how high-voltage isolation technology works
In this video, Tom Bonifield, a high-voltage isolation technologist at Texas Instrument in one of the high-voltage labs at TI, discusses the high-voltage isolation structure itself.This video is part of a series of videos on high-voltage reinforced isolation quality and reliability.
How high-voltage isolation technology works
This video is part of a series of videos on high-voltage reinforced isolation quality and reliability from Texas Instruments. The video is on the high-voltage isolation structure itself. Reinforced isolation technology at Texas Instruments is realised by using thick silicon dioxide capacitors combined in series. Each channel uses high-voltage isolation capacitors on both die.
35A power module features overcurrent protection
A 35A module from Texas Instruments (TI) which features overcurrent protection is now being shipped by Mouser Electronics. It is designed for compact PCI/PCIe, broadband, point-of-load, and medical equipment applications. TI’s PSM846C24 is a fixed-frequency, step-down power module that incorporates a controller, power MOSFETs, inductor, and associated components into a thermally enhanced, surface-mount package.
Automotive integrated-coil step-down ‘micro DC/DC’ converters
It has been announced that Torex Semiconductor has launched the XDL601/XDL602 series of HiSAT-COT control and 1.5A coil-integrated step-down ‘micro DC/DC’ converters for automotive applications. The XDL601/XDL602 series consist of ultra-compact step-down DC/DC converters with integrated coils and control ICs.
