Guided by machine learning, researchers at the Department of Energy’s Oak Ridge National Laboratory designed a record-setting carbonaceous supercapacitor material that stores four times more energy than the best commercial material. A supercapacitor made with the new material could store more energy — improving regenerative brakes, power electronics and auxiliary power supplies. “By combining a data-driven method and our research experience, we created a...

Knowles Precision Devices, recently released white paper based on Python Scipy.signal Toolbox to explore the theory behind poles and zeros and how these impact Q factor and filter performance. Quality factor, or Q factor, is a common shorthand figure of merit (FOM) for RF filters. It’s typically expressed as the ratio of stored versus lost energy per oscillation cycle. Steepness of skirts, selectivity, and insertion loss...

Bourns announced release of two new Data and Signal Surge Protective Device (SPD) families which significantly expands the company product line offering. The Bourns® Model 2510 and 2520 Series SPDs are DIN-Rail Data and Signal Surge Protective Devices. These protectors are designed to provide surge protection for 1-pair or 2-pair data lines with common reference potential in data, signal and communication systems. The Model...

Bourns releases a new Thermally Protected Surge Protective Device (TPMOV) family which will significantly expand our current product line offering. The Bourns® Model 1220 Series SPDs are PCB mounted TPMOVs which are surge suppressors with thermal protection designed to open in the event of overheating due to an abnormal overvoltage or Temporary Overvoltage (TOV) condition, interrupting any abnormal current that may be encountered up...

Würth Elektronik is extending its WR-TBL series by screwless push-in connectors in the 3.5mm and 3.81mm pitches. The new 4101, 8101, 4093, and 8093 series come close to matching the specifications of the screw-fixed connectors and can replace them. Another important feature for customers with SMT-dominated production lines: The THR series 8101 and 8093 are Read the original post at Würth Elektronik Extends Its...
