Sumida Metal Hybrid Inductors Contribute Less Resistance, Maintain Small Footprint

source: ECN mag news Sumida Corporation has made a significant expansion to its lineup of Metal Hybrid Inductors, known as the CDMT40 series. The three additional values offer more than double the inductance values of the earlier introductions, while maintaining the same small footprint. A newly developed composite material draws on the unique characteristics of […]

Cornell Dubilier’s Very Low-Profile Aluminum Electrolytic Capacitor Breaks Energy Density Barriers

source: Cornell Dubiler news Cornell Dubilier Electronics, Inc. (CDE) has announced a significant new development in aluminum electrolytic technology.  Its 85 ºC THA Series Thinpack capacitors are only 8.2mm thick, and 9mm for the 105 ºC THAS Series.  This is comparable in height to V-chip electrolytics, tantalums and board-mounted axials, yet offer much higher bulk-storage […]

Crystal Series and Parallel Resonances

source: EDN article A quartz crystal’s case will be stamped with the devices’ rated operating frequency, but that number is only an approximation to the real story which is that there is more than one crystal resonant frequency, even in the ideal case. (No pun intended.)

Component Shortages to Last ‘Longer Than Expected’

source: EPS news There’s no short-term relief ahead for electronics manufacturers that are scrambling for components. Tight supplies of capacitors and resistors are expected to last into mid-2018—longer than industry experts expected. The dreaded words “allocation” and “double-ordering” are coming up more frequently, meaning OEMs and EMS providers are facing long-term sourcing challenges.

Feedback from an independant laboratory on passives components failure analysis from all industry sectors

source: Serma Technologies, EPCI e-Symposium Abstract: SERMA TECHNOLOGIES is presenting failure statistics of all return parts analyzed during the last 5 years. For each family of passives components ( ceramic, tantalum, film capacitors and resistors) , percentage of defect will be given. The origin of defect (suppliers, board assembly process, or environment ) will also […]

Thick Film Chip Resistors: A Mass Market in Turmoil

source: D.Zogbi for TTI Market Eye article A current detailed analysis of the thick film chip resistor supply chain from raw material ores, engineered materials, substrates and pastes, unit production, distribution and consumption in each key product market reveals a market in turmoil entering the fourth quarter of CY 2017.
