MLCC ageing - decrease of capacitance with temperature and applied voltage - of BaTiO3 based ceramic capacitors (class II types such as X7R, X5R types...) is explained and illustrated in this Samsung Electro-Mechanics training video.
Frequency control specialist, Euroquartz has launched a range of surface mount, voltage-controlled crystal oscillators (VCXO). The EG_JF series is manufactured in the UK and offers high frequency (HF) outputs with low phase jitter performance.
Recent restart of lithium and tantalum ore production at the Wodgina mine in Western Australia is a good news for both supply chains. Tantalum is a core element for tantalum capacitors representing around 40% of end use of the tantalum ore. Re-opening of the Wodgina mine support tantalum supply diversity and pose a good foundation for further stability and growth according to Global Advanced Metals (GAM).
To meet the needs of military and avionics applications, Vishay Intertechnology, Inc. introduced a new EP2 high energy wet tantalum capacitor that delivers the industry’s highest capacitance per voltage rating and case size for this device type.
Yageo venture to acquire 30% Advanced Power Electronics (APEC) as one of the Taiwan’s biggest makers of metal-oxide semiconductor field-effect transistors (MOSFET). The Yageo alliance with APEC target to capture opportunities in analogue and power semiconductors through its global sales channels.
Coilcraft introduced XGL3520 molded power inductors that offer lowest DC losses and extremely low AC losses for a wide range of DC-DC converters. Additional performance benefits include a wider range of inductance values and improved Irms current ratings.
Global Advanced Metals (GAM) introduces high purity tantalum and niobium powders suitable for additive process including Cold Spray technology. The article written by GAM R&D Dr. Matthew Osborne and A. Calvin discusses the powder requirements and features suitable for cold spray technology applications.
The European Patent Office (EPO) announces that Skeleton scientists Jaan Leis, Mati Arulepp and Anti Perkson have been nominated for the European Inventor Award 2022 for the development of curved graphene material for supercapacitors.
Skeleton Technologies, the global technology leader in supercapacitor energy storage, and ZPUE, the largest manufacturer of electrical devices for electrical power distribution utilities in Poland, have entered into a commercial agreement to provide energy storage solutions to the Polish market.
Kyocera Corporation announced a plan to build the largest manufacturing facility it has ever operated in Japan, expanding production capacity for components including organic semiconductor packages and crystal device packages.
Supercapacitors from Skeleton Technology can assist locomotive batteries during engine start, especially in winter conditions, resulting in less energy being drawn from the battery, and extending battery life.
Smoltek Nanotech Holding AB (”Smoltek”) announces an update and a clearer definition of the company’s strategic objectives, with continued focus on industrialization and commercialization within its two business areas ultra-thin wafer based capacitors for the semiconductor industry and high performing cell material for electrolyzers used in hydrogen gas production.
Dual-use legislation is most commonly associated with pulse discharge capacitors. But it is very possible for high voltage MLCCs over 750V to fall under dual-use legislation even if the capacitor is not classified as a pulse discharge capacitor.
Expanding its comprehensive range of temperature sensors, Variohm EuroSensor has developed a new NTC thermistor especially designed for medical equipment use and particularly aimed at sensing small temperature changes in body and ambient medical area temperatures.
Electroninks, the leader in particle-free metal inks and advanced conductive materials, announced the confirmation of an enhanced particle-free silver ink product with aerosol jet printing compatibility for ultra-fine line printing requirements.
